Description

Technical Field

[0001] This invention relates to the technical field of hair care products, specifically to a hair growth and anti-hair loss care agent and its preparation method. Background Technology

[0002] In recent years, due to factors such as life stress, unhealthy diet, and irregular work and rest, more and more people are facing the problem of hair loss and graying. Premature hair loss and premature graying of hair are becoming increasingly common among young and middle-aged people.

[0003] Existing hair loss prevention and hair darkening products typically rely on chemically active ingredients (such as minoxidil). While these products may be effective to some extent, they are prone to side effects such as scalp allergies, itching, and dependence, and have a high relapse rate after discontinuation. Some herbal hair care products based on natural plant extracts, although safe, natural, and without side effects, often do not show significant hair growth and nourishing effects in actual use due to their simple formulas or unreasonable combinations.

[0004] Therefore, how to provide a safe, natural, side-effect-free hair care product that effectively nourishes and strengthens hair and prevents hair loss is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0025] The present disclosure is further illustrated below with reference to embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the disclosure.

[0026] This invention provides a hair growth and anti-hair loss conditioning agent. The basic formula of the conditioning agent includes: ginseng: 3 to 8 parts by weight; arborvitae leaf: 2 to 5 parts by weight; duckweed: 2 to 5 parts by weight; pine needle: 2 to 5 parts by weight; soapberry: 2 to 5 parts by weight; tribulus terrestris: 2 to 4 parts by weight; angelica: 2 to 4 parts by weight; eclipta prostrata: 2 to 4 parts by weight; mulberry bark: 2 to 4 parts by weight; privet fruit: 1 to 4 parts by weight; Sichuan pepper: 1 to 4 parts by weight; drynaria fortunei: 1 to 4 parts by weight; clematis chinensis: 1 to 4 parts by weight; fleeceflower root: 1 to 4 parts by weight; polygonum multiflorum: 1 to 4 parts by weight; soapberry: 1 to 4 parts by weight; and ganoderma lucidum: 1 to 3 parts by weight.

[0027] Preferably, in some embodiments of the present invention, the basic formula of the raw materials used in the care agent specifically includes: ginseng: 4 to 6 parts by weight; arborvitae leaves: 3 to 4 parts by weight; duckweed: 3 to 4 parts by weight; pine needles: 3 to 4 parts by weight; soapberry: 3 to 4 parts by weight; tribulus terrestris: 2.5 to 3.5 parts by weight; angelica: 2.5 to 3.5 parts by weight; eclipta prostrata: 2.5 to 3.5 parts by weight; mulberry bark: 2.5 to 3.5 parts by weight; privet fruit: 2 to 3 parts by weight; Sichuan pepper: 2 to 3 parts by weight; drynaria fortunei: 2 to 3 parts by weight; clematis chinensis: 2 to 3 parts by weight; fleeceflower root: 2 to 3 parts by weight; Polygonum multiflorum: 2 to 3 parts by weight; soapberry: 2 to 3 parts by weight; Ganoderma lucidum: 1.5 to 2.5 parts by weight.

[0028] In this invention, ginseng is used to promote hair growth. Ginseng's function is to replenish vital energy, which can improve blood circulation in the scalp, providing sufficient nutrition to hair follicles. Ginsenosides can promote the proliferation of dermal papilla cells in hair follicles and activate the activity of hair matrix cells. When qi is deficient, blood circulation is weak, and hair follicles are prone to malnutrition and hair loss. Ginseng can also enhance the body's immunity, reduce hair follicle atrophy caused by qi deficiency, and thus play a role in preventing hair loss.

[0029] Arborvitae leaves contain flavonoids, which can inhibit 5α-reductase, while also exerting anti-inflammatory effects, reducing excessive scalp oil secretion, and alleviating seborrheic alopecia. Arborvitae leaves can also promote scalp blood circulation, providing nutrition to melanocytes and helping to improve gray hair.

[0030] Duckweed has a pungent and cold nature, and can dispel wind-heat and promote urination. In addition, duckweed contains duckweed polysaccharides, which can promote scalp vasodilation, improve microcirculation, and accelerate the transformation of hair follicles from the resting phase to the growth phase. Duckweed can also clear heat and detoxify, reducing scalp heat-toxin-induced hair follicle inflammation (such as hair loss caused by folliculitis).

[0031] Pine needles contain volatile oils (such as α-pinene) and vitamins C and E, which have antibacterial and antioxidant effects. They can inhibit the growth of scalp fungi (such as Malassezia) and reduce dandruff and inflammatory hair loss. Pine needles are also rich in trace elements (such as iron and copper). Copper is a coenzyme of tyrosinase (a key enzyme in melanin synthesis), which can help promote melanin production.

[0032] As a natural cleanser, soapberry's saponin components can gently cleanse scalp oil and dirt, maintain the balance of the scalp's microenvironment, and reduce hair loss caused by clogged hair follicles (strengthening hair starts with cleansing). Soapberry's antibacterial properties can also reduce the risk of scalp infections, indirectly protecting hair follicles.

[0033] Tribulus terrestris contains tribulus saponins, which can promote the expression of hair follicle growth factors (such as VEGF) and accelerate hair growth. Tribulus terrestris can also regulate the body's hormone balance (especially having an auxiliary effect on androgenetic alopecia) and reduce hair follicle atrophy.

[0034] Blood deficiency is often accompanied by gray hair. Angelica sinensis is used to nourish and invigorate blood. Its volatile oil and ferulic acid can improve scalp microcirculation, increase blood supply to hair follicles, and promote melanin synthesis by melanocytes.

[0035] Eclipta prostrata contains tannins, saponins, and other components, which can enhance tyrosinase activity and promote melanin production. Liver and kidney deficiency is one of the core pathogenic mechanisms of hair loss; Eclipta prostrata can also nourish the liver and kidneys, reducing hair loss caused by kidney essence deficiency.

[0036] Excessive oil can clog hair follicles, leading to seborrheic alopecia. Mulberry bark is sweet and cold in nature, and can clear heat and promote diuresis. The mulberry bark contains mulberry ketones, which can inhibit scalp oil secretion and exert anti-inflammatory effects, reducing inflammation around hair follicles.

[0037] Privet fruit contains oleanolic acid and privetin, which can nourish the liver and kidneys. It also has strong antioxidant properties, which can delay the aging of melanocytes in hair follicles and reduce gray hair. Privet fruit can also enhance the body's antioxidant capacity, protect hair follicles from free radical damage, and promote the proliferation of hair matrix cells.

[0038] Traditional Chinese medicine believes that qi stagnation leads to blood stasis. Sichuan pepper can soothe the liver and regulate qi, thus relieving poor blood circulation in the scalp caused by emotional stress (such as liver stagnation) and reducing qi stagnation-related hair loss. In addition, Sichuan pepper can also enhance the efficacy of other blood-activating herbs (such as angelica and clematis) by regulating qi.

[0039] Drynaria fortunei contains total flavonoids, which can activate hair follicle stem cells and promote hair follicles to enter the growth phase, especially effective for hair loss caused by kidney deficiency. Drynaria fortunei can also strengthen the connection between hair follicles and scalp, reducing hair loss caused by loose hair roots.

[0040] The volatile components of Clematis armandii can promote the penetration of other drugs through the scalp barrier (enhancing the transdermal absorption of ginseng, angelica, etc.), while improving local microcirculation and delivering more nutrients to hair follicles.

[0041] Polygonum multiflorum needs to be processed before use. It contains emodin, lecithin, and other substances that can promote the synthesis of melanin by melanocytes. In addition, Polygonum multiflorum can nourish the liver and kidneys and enhance the ability of hair follicles to absorb nutrients.

[0042] The effects of soapberry are similar to those of soapberry. Its saponin components can cleanse the scalp and balance oil production, while it also contains antioxidants such as tea polyphenols to protect hair follicles from free radical damage. Soapberry also has natural antibacterial effects (effective against Malassezia and other fungi), which can reduce hair loss caused by scalp inflammation.

[0043] Reishi mushroom contains polysaccharides and triterpenoids, which can enhance the body's immunity and reduce hair loss caused by immune abnormalities (such as alopecia areata); it also has antioxidant properties, delaying hair follicle aging. Reishi mushroom can also regulate the scalp microenvironment, promote the survival of dermal papilla cells in hair follicles, and reduce apoptosis.

[0044] According to the TCM theory of syndrome differentiation and treatment, and comprehensive conditioning, the causes of hair loss and gray hair in TCM are mostly due to liver and kidney deficiency, qi and blood deficiency, blood heat generating wind, and qi stagnation and blood stasis. The formula used in this invention takes into account four aspects: nourishing the liver and kidneys, replenishing qi and blood, clearing heat and removing dampness, and promoting blood circulation. Polygonum multiflorum, Ligustrum lucidum, Eclipta prostrata, and Drynaria fortunei are used to improve hair loss and gray hair caused by liver and kidney deficiency. Ginseng and Angelica sinensis address the lack of nourishment to hair follicles caused by qi and blood deficiency. Platycladus orientalis leaves, Morus alba root bark, and Spirodela polyrhiza improve seborrheic alopecia caused by blood heat and excessive oil. Clematis chinensis, Melia toosendan, and Tribulus terrestris can relieve insufficient blood supply to the scalp caused by qi stagnation and blood stasis.

[0045] Hair loss (especially androgenetic alopecia) involves multiple aspects, including hair follicle atrophy, insufficient blood supply, inflammatory response, hormonal imbalance, and melanin reduction. This invention, through the above formula, uses ginseng (to replenish qi), angelica (to nourish blood), and he shou wu (to darken hair) as the principal herbs, establishing a nourishing foundation. It uses arborvitae leaf (to prevent hair loss), drynaria rhizome (to promote hair growth), and eclipta prostrata (to darken hair) as the assistant herbs. It uses mulberry bark (to control oil), tribulus terrestris (to regulate hormones), and soapberry (to cleanse) as adjuvant herbs to improve the scalp environment; and it uses clematis root (to promote penetration) and Sichuan pepper (to regulate qi) as guiding herbs to direct the medication to the affected area. This achieves a multi-target synergistic effect, covering all aspects of hair loss and providing good hair growth and nourishment effects for various types of hair loss patients.

[0046] Preferably, in some embodiments of the present invention, based on the above formula, the raw materials used in the care agent further include: Astragalus membranaceus: 3 to 8 parts by weight.

[0047] The core functions of astragalus are to replenish qi and raise yang, strengthen qi and consolidate the exterior, promote body fluid production and nourish blood, and promote blood circulation and remove stagnation. In hair care, its effects can be summarized as: strengthening the ability of qi and blood to generate and transform, promoting the circulation of qi and blood to the scalp and hair follicles, and solving the problems of blood deficiency making it difficult to nourish hair and qi stagnation making it difficult to reach the apex. Astragalus can also protect the skin surface and reduce damage to hair follicles from external pathogens. Specifically, the scalp is the exterior of the head and is easily invaded by external pathogens such as wind, dampness, and heat, which can damage hair follicles. Astragalus's ability to consolidate the skin surface can enhance the scalp's resistance and reduce inflammatory hair loss caused by external pathogens. Astragalus contains astragalus polysaccharides, astragaloside A, and other components, which can dilate blood vessels (especially microvessels), increase blood flow to the scalp, improve the supply of oxygen and nutrients (such as amino acids and trace elements) to hair follicles, and activate resting hair follicles to enter the growth phase. Astragalus also exerts anti-inflammatory and immunomodulatory effects. Its active ingredients can inhibit the release of inflammatory factors (such as TNF-α and IL-6), reduce chronic inflammation around hair follicles, and regulate the local immune balance of the scalp, preventing autoimmune damage to hair follicles. Astragalus's antioxidant activity can scavenge free radicals on the scalp, reducing oxidative damage to hair follicle cells; and by inhibiting apoptosis of hair follicle epithelial cells, it prolongs the hair follicle growth phase.

[0048] More preferably, in some embodiments of the present invention, based on the above formula, the raw materials used in the care agent further include: elm bark: 0.5 to 2.5 parts by weight.

[0049] Elm bark (the dried bark of the elm tree, a plant in the elm family) is recorded in traditional Chinese medicine as having the functions of clearing heat and dampness, detoxifying and astringing sores, and moisturizing dryness and relieving itching. Its core value in hair care lies in regulating the scalp microenvironment. For excessive oiliness, itching, and clogged hair follicles caused by damp-heat accumulation on the scalp, elm bark can clear heat and dampness, reducing the pressure of oil accumulation on the hair follicles. Elm bark can also repair the scalp barrier; its astringent properties can promote the healing of scalp damage (such as scratches and inflammatory erosions), repair the stratum corneum, maintain the scalp's moisture-locking and protective functions, and provide a stable growth environment for hair follicles. Elm bark contains a large amount of mucilage (polysaccharide components) and tannins, which can form a protective film on the scalp surface, reducing moisture loss and relieving dryness and flaking. At the same time, tannins can promote epithelial cell proliferation and accelerate scalp barrier repair (especially suitable for barrier damage caused by excessive cleaning or inflammation). Elm bark extract has an inhibitory effect on common scalp pathogens such as Staphylococcus aureus and Malassezia, which can reduce seborrheic dermatitis caused by microbial infections (seborrheic alopecia is often accompanied by such infections). It also inhibits histamine release, relieves scalp itching, and prevents follicle damage caused by scratching. Finally, the mucilage in elm bark has certain surface activity, which can enhance the cleansing power of soapberry and soapberry in existing formulas while neutralizing their irritants, preventing compensatory oil production on the scalp due to excessive degreasing, and maintaining the scalp's water-oil balance.

[0050] The formula of this invention already covers multiple dimensions, including nourishing blood and promoting hair growth (ginseng, angelica), cooling blood and preventing hair loss (arborvitae leaf, eclipta prostrata), penetrating and promoting absorption (cleansing and regulating) (soapberry, soapberry). However, there is still room for further improvement in its effects. Firstly, simply nourishing blood has a relatively weak effect on promoting qi; secondly, it lacks specificity in repairing the scalp barrier. The addition of astragalus and elm bark precisely addresses these two points, creating a synergistic effect. Astragalus, angelica, and ginseng work together to strengthen the energy supply of qi and blood to the hair follicles. Angelica nourishes blood, and ginseng replenishes qi, but ginseng tends to strongly replenish vital energy, while astragalus tends to promote yang and remove stagnation. The combination of the two can form a closed loop of sufficient qi-blood generation-blood circulation. In other words, the stagnation-removing and meridian-clearing effect of astragalus can enhance the efficacy of ginseng and angelica, promoting qi and blood to reach the scalp hair follicles more efficiently (especially the vertex), solving the problem of sufficient blood but insufficient blood reaching the hair follicles. Astragalus can be combined with Platycladus orientalis leaves and Tribulus terrestris. Platycladus orientalis leaves and Tribulus terrestris can cool the blood, dispel wind, and inhibit follicular inflammation. However, one of the root causes of inflammation is stagnant heat caused by poor blood circulation. Astragalus, by tonifying qi and promoting blood circulation, can reduce chronic inflammation caused by qi stagnation and blood stasis, enhancing the anti-inflammatory effect from the source and forming a comprehensive treatment with existing anti-inflammatory components. Elm bark, mulberry bark, and Sichuan pepper can work together to optimize the basic environment for hair follicle survival. Mulberry bark and Sichuan pepper can clear heat and dry dampness, but they lack the effect of repairing the scalp barrier. The mucilage and tannins in elm bark can repair the scalp stratum corneum damaged by inflammation while clearing heat, avoiding excessive drying and dampness that leads to dry and flaky scalp, and maintaining a stable physical environment around the hair follicles. Gleditsia sinensis and Sapindus mukorossi have strong cleansing power, which may lead to excessive degreasing of the scalp in some people. The mucilage in elm bark can buffer its irritation, creating a balance of cleansing, moisturizing, and protection, reducing itching and hair follicle damage caused by dry scalp, and achieving gentle care.

[0051] In summary, astragalus can enhance blood circulation and reduce inflammation, thereby increasing hair follicle activation (shortening the resting phase); elm bark, by repairing the scalp barrier and regulating sebum production, may reduce the recurrence rate of hair loss (reducing triggers). Together, these two ingredients make the formula of this invention superior to existing products in terms of hair regrowth speed and long-lasting hair loss prevention. Regarding the target population, the addition of astragalus and elm bark not only makes the formula suitable for those with simple blood and qi deficiency or blood heat-related hair loss, but also covers those with sensitive scalps and damaged scalp barriers (such as seborrheic dermatitis accompanied by hair loss), thus expanding its applicability.

[0052] Preferably, in some embodiments of the present invention, in addition to adding 3 to 8 parts by weight of Astragalus membranaceus and 0.5 to 2.5 parts by weight of elm bark to the above-mentioned basic formula, the raw materials used in the care agent of the present invention also include: Rehmannia glutinosa: 2 to 4 parts by weight; black sesame: 1 to 4 parts by weight; wolfberry: 1 to 4 parts by weight; Ligusticum chuanxiong: 1 to 3 parts by weight; Cuscuta chinensis: 1 to 3 parts by weight; ginger: 0.5 to 2 parts by weight.

[0053] Further preferably, in some embodiments of the present invention, in addition to adding 4 to 6 parts by weight of Astragalus membranaceus and 1 to 2 parts by weight of elm bark to the above-mentioned basic formula, the raw materials used in the care agent of the present invention also include: Rehmannia glutinosa: 2.5 to 3.5 parts by weight; black sesame: 2 to 3 parts by weight; wolfberry: 2 to 3 parts by weight; Ligusticum chuanxiong: 1.5 to 2.5 parts by weight; Cuscuta chinensis: 1.5 to 2.5 parts by weight; ginger: 0.5 to 1.5 parts by weight.

[0054] Rehmannia glutinosa (Shu Di Huang) nourishes yin and blood, replenishes essence and marrow, and can be used for premature graying and hair loss caused by blood deficiency, chlorosis, and liver and kidney yin deficiency. It is also rich in catalpol and rehmannia glutinosa, which have significant antioxidant activity, clearing free radicals from the scalp and reducing oxidative damage to hair follicles. Furthermore, it promotes hematopoiesis, increases peripheral blood erythrocyte and hemoglobin levels, improves the oxygen-carrying capacity of scalp microcirculation, and provides sufficient nutrition to hair follicles.

[0055] Black sesame seeds are used to nourish the liver and kidneys, replenish essence and blood, and darken hair. They are used to treat premature graying, hair loss, and dryness caused by insufficient essence and blood. Furthermore, black sesame seeds are rich in unsaturated fatty acids (such as linoleic acid), protein, vitamin E, and trace elements (iron and zinc), which can directly provide nutrition to hair follicles and promote the proliferation of hair matrix cells. In particular, vitamin E is a powerful antioxidant that can protect hair follicles from free radical damage and delay follicle atrophy. The oil components of black sesame seeds can moisturize the scalp's stratum corneum, improve the dry scalp environment, and reduce hair loss caused by damage to the scalp barrier.

[0056] Goji berries are used to nourish the liver and kidneys, benefit essence and improve eyesight, and are particularly effective in treating hair loss caused by liver and kidney deficiency. The main active ingredient in goji berries, goji berry polysaccharide (LBP), can enhance immune function, regulate the local immune microenvironment of the scalp, and reduce hair follicle damage caused by autoimmune abnormalities (such as alopecia areata).

[0057] Ligusticum chuanxiong can invigorate blood circulation, dispel wind, and relieve pain, thus improving insufficient blood supply to the scalp caused by blood stasis. Ligusticum chuanxiong contains components such as tetramethylpyrazine and ferulic acid, which can dilate scalp blood vessels (especially arterioles), increase local blood flow, improve blood perfusion to hair follicles, and promote nutrient transport. Ligusticum chuanxiong can also inhibit platelet aggregation, reduce blood viscosity, alleviate scalp microcirculation stagnation, and provide a smooth metabolic environment for hair follicles.

[0058] Cuscuta chinensis can nourish the kidneys and replenish essence, as well as nourish the liver and improve eyesight. It is particularly effective for hair loss and premature graying caused by liver and kidney deficiency and depletion of essence and blood. Cuscuta chinensis contains dodderin and flavonoids, which can regulate the hypothalamic-pituitary-gonadal axis, balance androgen levels in the body (especially for androgenetic alopecia, it can inhibit 5α-reductase activity and reduce the inhibitory effect of dihydrotestosterone on hair follicles), promote the proliferation of hair follicle stem cells, delay the entry of hair follicles into the resting phase, and prolong the hair growth phase. Ginger has the properties of relieving exterior syndromes and dispelling cold, warming the meridians and promoting blood circulation. When applied externally, it can stimulate blood circulation in the scalp and promote hair growth. The main active ingredient in ginger, gingerol (shogaol, gingerene), can stimulate scalp vasodilation, activate local blood circulation, enhance hair follicle activity, and also has anti-inflammatory and antibacterial effects. It can inhibit the growth of pathogenic bacteria such as Malassezia on the scalp and reduce hair loss associated with seborrheic dermatitis.

[0059] The basic formula already covers the effects of replenishing qi, promoting blood circulation, clearing heat, nourishing the liver and kidneys, and promoting transdermal absorption. The six newly added herbs complement and enhance the basic formula in the following ways, significantly improving the overall effect. Rehmannia glutinosa, black sesame seeds, wolfberries, and Cuscuta chinensis work together to enhance the effects of nourishing the liver and kidneys and replenishing essence and blood. Rehmannia glutinosa focuses on replenishing blood, black sesame seeds on replenishing essence, wolfberries on nourishing yin and regulating immunity, and Cuscuta chinensis on tonifying kidney yang to promote the generation of essence and blood. The four herbs work synergistically to improve the nutritional deficiencies in hair follicles caused by liver and kidney insufficiency and deficiency of essence and blood. Together with the original Polygonum multiflorum and Ligustrum lucidum, they form a yin-yang tonifying network, providing a material basis for hair growth from the root. Chuanxiong (Ligusticum striatum) works synergistically with the existing Angelica sinensis and Astragalus membranaceus to tonify Qi, invigorate blood, and promote Qi circulation. Together, these three ingredients enhance scalp microcirculation, ensuring smooth delivery of essence and blood to the hair follicles. Simultaneously, the warming effect of ginger further activates vasoactivity, synergizing with the vasodilatory effects of Chuanxiong to enhance blood perfusion to the hair follicles, overcoming the potential limitation of the original formula where tonification was insufficient for effective circulation. In terms of antioxidants, the antioxidant components (catalpol, goji berries, and vitamin E) of Rehmannia glutinosa, Lycium barbarum, and black sesame seeds, along with the existing Ganoderma lucidum (Ganoderma lucidum polysaccharides) and Polygonum multiflorum (emodin), form a stronger free radical scavenging network, protecting hair follicle cell DNA. In terms of anti-inflammatory effects, Chuanxiong (ferulic acid) and ginger (gingerol), along with the existing Platycladus orientalis leaves (quercetin) and Morus alba root bark (morula bark extract), synergistically inhibit scalp inflammatory factors and reduce fibrosis around the hair follicles. At the level of hormone regulation, the 5α-reductase inhibition of Cuscuta chinensis, synergistically with the existing Drynaria fortunei (naringin), more effectively improves the miniaturization of hair follicles in androgenetic alopecia. Gingerol from ginger can directly stimulate the proliferation of hair follicle matrix cells, synergistically with the existing Clematis chinensis (which promotes transdermal drug absorption), enhancing the accumulation efficiency of blood-activating components such as Ligusticum chuanxiong and Angelica sinensis, as well as nutrients such as Rehmannia glutinosa and black sesame in the hair follicles. Simultaneously, Cuscuta chinensis's effect of promoting hair follicle stem cell activation, together with the existing Drynaria fortunei (which promotes osteoblast-like cell activity and indirectly supports the hair follicle matrix), forms a closed loop of stem cell activation-nutrient supply-signal transduction, accelerating the transition of hair from the resting phase to the growth phase.

[0060] In summary, Rehmannia glutinosa, black sesame, wolfberry, Ligusticum chuanxiong, Cuscuta chinensis, and ginger work together with the original formula to achieve a multi-target, multi-level synergistic effect through four dimensions: strengthening the nourishment of essence and blood, upgrading blood circulation, improving hair follicle protection, and activating regeneration signals. The complementary pharmacological components (such as the superposition of antioxidants, the synergy of anti-inflammatory components, and the enhancement of hormone regulators) achieve better results, significantly improving the overall efficacy of the hair care product in hair growth, hair loss prevention, hair strengthening, and improvement of hair quality.

[0062] This invention also provides a method for preparing a hair growth and anti-hair loss care agent. This method is used to prepare a care agent as described in any of the above technical solutions, and the method includes: S100: Remove impurities from the raw materials, wash, dry, and pulverize to obtain powder; S200: Mix the powder with water, heat and reflux to extract, filter, concentrate under reduced pressure to obtain a paste.

[0063] Preferably, after S100 and S200, the preparation method further includes: S300: Mix the extract with surfactant, humectant, thickener, preservative, pH adjuster, emulsifier and water to prepare an emulsion.

[0064] Preferably, after S100 and S200, the preparation method further includes: S400: Oil phase core material is prepared by using an extract paste. S500: Microcapsules are obtained by coating the wall material outside the oil phase core material; S600: Microcapsules, surfactants, humectants, thickeners, preservatives, pH adjusters, emulsifiers and water are mixed to prepare a microcapsule emulsion.

[0065] Example 1 In this embodiment, a series of care agent extract samples were prepared. The raw material ratios are listed in Table 1, and the preparation process is as follows.

[0066] S1. Pre-treatment of Chinese herbal raw materials (removal of impurities, washing, drying, and pulverization) Remove impurities: Each Chinese herbal medicine raw material is manually selected, removing moldy, insect-infested, or withered parts (such as rotten roots of ginseng and withered yellow leaves of arborvitae). Non-medicinal parts are separated (such as fibrous roots of ginger and old, hard branches of pine needles) to ensure that the purity of the raw materials is ≥99%. Cleaning: Rinse the raw material quickly three times with deionized water (10 seconds each time) to prevent loss of active ingredients. For raw materials with mud or sand on the surface (such as elm bark and drynaria), gently brush with a soft brush and then rinse until the washing solution is clear. drying: A vacuum low-temperature drying oven is used, with the temperature set at 50±2℃ and the vacuum degree at -0.08MPa. The raw materials are placed in layers (thickness ≤3cm) and dried for 4-6 hours until the moisture content of the raw materials is ≤8% (tested with a moisture analyzer, with a sample size ≥5g). Shred: The dried raw materials are pulverized using a Chinese herbal medicine pulverizer and passed through an 80-mesh sieve (sieve aperture 0.18mm). The sieved powder is collected in a sterile stainless steel container, and the coarse particles on the sieve are pulverized again to ensure that the powder passing rate is ≥95%. After pulverization, the powder is immediately sealed and stored in a dark place (light blocking rate ≥90%) and at a low temperature (≤25℃) for no more than 48 hours. S2. Obtain the extract (extraction by heating and reflux, filtration, and concentration under reduced pressure). Add water and mix: Add the powder to the multi-functional extraction tank, add deionized water at a solid-liquid ratio of 1:10 (g / mL) (i.e., 1 kg of powder to 10 L of water), stir (60 r / min) for 5 minutes to fully wet the powder, and soak for 30 minutes. Reflux extraction: Turn on the steam heater in the jacket of the extraction tank and heat it to 95±2℃ (boiling state), maintaining a gentle reflux extraction for 2 hours. Stir every 30 minutes (2 minutes each time) during the extraction process to avoid localized overheating. After the first extraction, release the extract, and perform a second extraction on the residue under the same conditions (adding water at a solid-liquid ratio of 1:8) for 1.5 hours. Combine the two extracts and record the volume (approximately 18-20 L / kg powder).

[0067] filter: The extract was first coarsely filtered through a 100-mesh filter cloth to remove large particles of residue; then finely filtered through a 0.45μm microporous membrane, and the clear filtrate was collected (transmittance ≥90%, detection at 450nm wavelength). Reduced pressure concentration: The filtrate was transferred to a rotary evaporator and the following conditions were set: temperature 60±5℃, vacuum -0.09MPa; the concentration was carried out until the relative density reached 1.20-1.25 (measured at 60℃ using a densitometer) to obtain the extract. The mixture was stirred continuously during concentration to prevent it from sticking to the walls and charring. After cooling to room temperature, the extract was transferred to a sterile container and refrigerated at 4℃.

[0068] Process details and precautions: Processed Polygonum multiflorum must be prepared using black bean juice (according to the standards of the Chinese Pharmacopoeia); raw Polygonum multiflorum is prohibited (it contains hepatotoxic components). Fresh ginger must be sliced ​​to avoid prolonged oxidation (gingerol is easily degraded). Black sesame seeds must be roasted at a low temperature (80℃, 15 minutes) and then ground to enhance the extraction efficiency of oil components. Reflux extraction temperature must not exceed 100℃ (to avoid damage to heat-sensitive components such as ginsenosides and Ganoderma lucidum polysaccharides). Vacuum concentration temperature ≤65℃ to prevent carbonization of the extract. Extracts showing mold spots or off-odors must be discarded (due to the risk of microbial contamination). Table 1 Example 2 This embodiment prepared a series of care emulsion samples 1 to 7, each using extract samples 1 to 7 as the active ingredient. Based on a total mass of 100%, the raw material ratio was: extract sample: 30%, sodium lauroyl glutamate: 2.0%, glycerin: 5.0%, xanthan gum: 3.0%, phenoxyethanol: 0.5%, cetearyl alcohol polyether-20: 5.0%, with the balance being deionized water. In addition, an appropriate amount of citric acid was added as a pH adjuster to ensure the emulsion sample was neutral or slightly acidic.

[0069] The preparation processes for nursing emulsion samples 1 to 7 are as follows.

[0070] Glycerin and sodium lauroyl glutamate were diluted with deionized water to a concentration of 50% and stirred until completely dissolved. 70% of the prescribed amount of deionized water was added to an emulsifying vessel and heated to 70±5℃. The diluted glycerin, sodium lauroyl glutamate, and xanthan gum were added sequentially, and the mixture was stirred (300 rpm) for 10 minutes until dissolved to obtain the aqueous phase. The aqueous phase was kept warm for later use. Add the extract and cetearyl alcohol polyether-20 to the remaining deionized water, stir (500 r / min) for 10 minutes, then slowly pour the mixture into the aqueous phase (50 mL / min), turn on the homogenizer (2000 r / min) to emulsify for 15 minutes, cool to below 45°C, add phenoxyethanol, and stir until homogeneous.

[0071] The pH of the system was adjusted to 6.5 using a 10wt% citric acid solution. The mixture was then sterilized by filtration through a 0.22-micron filter membrane. The appearance (milky white, uniform emulsion, without stratification or sedimentation) and viscosity (5000-8000 mPa·s at 25℃, measured using a rotational viscometer) were tested. After passing the tests, the mixture was filled in a sterile environment (using brown, light-proof bottles to prevent photolysis of the active ingredients) and sealed to obtain the finished product. Performance testing This study employed a double-blind, randomized controlled trial design. Participants were selected based on the following criteria: age 18-50 years, meeting the diagnostic criteria for androgenetic alopecia or telogen effluvium (more than 100 hairs / day), hair density of 20-40 hairs / cm², melanin content in hair shaft <50 AU, no history of scalp inflammation, allergies, or systemic diseases, and no use of hair regrowth drugs or products in the past 3 months. Exclusion criteria included: alopecia areata, cicatricial alopecia; pregnant or lactating women; and allergies to the test ingredients (such as ginseng or Polygonum multiflorum). A total of 80 participants were randomly assigned to 8 groups (experimental groups 1-7 and a control group), with 10 participants in each group. The male-to-female ratio was 1:1, and participants were balanced in age and degree of hair loss (baseline data showed no statistically significant difference, P > 0.05). A standardized hair care procedure was followed. Experimental groups 1-7 used 15ml of conditioning lotion (samples 1-7) sequentially at 38℃, massaging for 20 minutes before washing with a silicone-free shampoo (containing no hair growth ingredients) every two days. The control group received 15ml of a placebo (containing no herbal active ingredients). During the trial, the use of other hair care products was prohibited, and diet and sleep patterns were maintained (daily hair loss was recorded as a supplementary indicator). The trial lasted 30 days, with hair density and melanin content measured on day 0 (baseline) and day 30. Hair density was measured using a hair follicle analyzer (resolution ≥ 10 megapixels) on a 3cm area behind the front hairline at the top of the head, with an area of ​​2cm². 2 The number of hairs per unit area (hair / cm²) was counted, and the average of three measurements was taken. The melanin content of the hair shaft was determined using a spectrometer (400-700nm wavelength), and the melanin reflectance value of the hair shaft in the above area was converted to AU (the higher the value, the richer the melanin). The average of 20 hairs was taken. The test results are listed in Table 2.
