Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shampooing, in particular to a hair loss prevention shampoo. BACKGROUND

[0002] Most of the shampoos on the market currently use surfactants as the main cleaning component to maintain scalp cleanliness by removing the oil and dirt on the hair surface. However, in actual use, excessive cleaning or improper surfactant ratio can easily disrupt the balance of the scalp sebum film, leading to deterioration of the hair follicle environment and exacerbation of hair loss. In particular, in traditional formulations containing strong anionic surfactants, the scalp barrier function is weakened and the stratum corneum loses a lot of moisture, making it difficult to balance the cleaning power and mildness.

[0003] To improve the above problems, some hair loss prevention shampoos attempt to introduce plant extracts, such as ginseng, cypress leaves, and radix falcaliae, to promote blood circulation in the hair follicle, inhibit sebum secretion, and delay hair follicle degradation. However, in existing technologies, most plant extracts are added in limited amounts or are not evenly distributed, making it difficult to fully exert their physiological activity. In addition, the compatibility between different extracts is poor, and if there is no suitable solvent system or emulsion structure support, precipitation or failure can easily occur, leading to a decrease in product stability and user experience.

[0004] On the other hand, hair loss prevention products often ignore the softness and conditioning of the hair. Traditional conditioning systems are mainly based on silicone oil, which can improve the feel but can easily cause pore blockage, which is contrary to the mechanism of hair loss prevention. Non-silicone system conditioners also have deficiencies in improving the feel of the hair, making it difficult to balance the comprehensive performance of cleaning, hair loss prevention, and softness. SUMMARY

[0005] According to an embodiment of the present application, a hair loss prevention shampoo is provided to solve the problems raised in the background.

[0006] In a first aspect of the present application, a hair loss prevention shampoo is provided.

[0007] The hair loss prevention shampoo comprises water, anionic surfactant, amphoteric surfactant, non-ionic surfactant, conditioning agent, preservative, pH adjuster, colorant, and hair loss prevention active ingredient. The anionic surfactant comprises sodium laureth sulfate and sodium cocoyl glutamate. The amphoteric surfactant is cocamidopropyl betaine. The non-ionic surfactant is laureth-7. The conditioning agent comprises polyquaternium-10, honey, and silicone oil emulsion. The preservative comprises phenoxyethanol and piroctone olamine. The pH adjuster is citric acid; The colorant is caramel color; The anti-hair loss active ingredients include arborvitae leaf extract, ginseng extract, and Polygonum multiflorum extract.

[0008] Preferably, the water content is 65-75% by weight, the anionic surfactant content is 8-12% by weight, the amphoteric surfactant content is 3-6% by weight, the nonionic surfactant content is 1-3% by weight, the conditioner content is 2-5% by weight, the preservative content is 0.5-1.5% by weight, the pH adjuster content is 0.2-0.8% by weight, the colorant content is 0.05-0.2% by weight, and the anti-shedding active ingredient content is 1-5% by weight.

[0009] Preferably, the mass ratio of sodium lauryl ether sulfate to sodium cocoyl glutamate is (2-3):(1).

[0010] Preferably, the mass ratio of polyquaternium-10, hydroxypropyltrimethylammonium chloride honey, and silicone oil emulsion in the conditioning agent is (1-2):(2-3):(4-6).

[0011] Preferably, the mass ratio of Platycladus orientalis leaf extract, ginseng extract, and Polygonum multiflorum extract in the anti-hair loss active ingredients is (1-2):(0.8-1.5):(0.8-1.5).

[0012] Preferably, the shampoo has a pH value of 5.5 to 6.0.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages: This invention provides an anti-hair loss shampoo that, firstly, uses a combination of sodium lauryl ether sulfate and ammonium lauryl sulfate as the main cleansing system, significantly reducing damage to the sebum film while ensuring effective detergency. The synergistic effect of the two anionic surfactants produces a fine and rich lather, with gentle and stable cleansing power, avoiding the scalp dryness and itching problems caused by traditional strong degreasing shampoos, and improving the scalp barrier function.

[0014] Secondly, this invention introduces cocamide MEA as an adjuvant, which can both thicken and stabilize foam, and improve the smoothness of the wash. Combined with humectants such as butylene glycol and glycerin, it can maintain scalp moisture balance during shampooing, reduce moisture loss from the stratum corneum, and thus provide a favorable environment for the absorption of anti-hair loss active ingredients.

[0015] Furthermore, this invention introduces composite conditioning agents such as polyquaternium-10, polyquaternium-52, and silicone oil emulsion into the conditioning system, which allows the hair to form a smooth film layer after washing, reducing static electricity and tangling, improving combing smoothness, and significantly improving hair roughness and breakage. At the same time, the proportion of non-silicone oil conditioning agents is properly controlled, avoiding the problem of silicone clogging pores and maintaining the patency of hair follicles on the scalp.

[0016] Furthermore, the core anti-hair loss active system of this invention is composed of extracts from Platycladus orientalis leaves, Polygonum multiflorum, ginseng, ginger root, Salvia miltiorrhiza, and Gleditsia sinensis seeds. These plant active ingredients work synergistically to promote scalp microcirculation, strengthen nutrient supply to hair follicles, and inhibit 5α-reductase activity, thereby reducing hair follicle atrophy and hair loss at the root. The combined action of Platycladus orientalis leaf and ginseng extracts effectively prolongs the hair growth cycle, while ginger root and Gleditsia sinensis extracts improve the scalp metabolic environment, exhibiting significant dual effects of preventing hair loss and nourishing hair.

[0017] Furthermore, this invention employs a preservative system comprised of phenoxyethanol, ethylhexylglycerin, and piroctone olamine salt, which is rationally formulated and has a broad-spectrum antibacterial effect, ensuring the product's microbial stability and avoiding scalp irritation caused by traditional preservatives. Simultaneously, precise pH control with citric acid ensures the shampoo is generally weakly acidic (pH 5.5–6.0), better suited to the physiological characteristics of the scalp, enhancing comfort and safety.

[0018] In summary, the anti-hair loss shampoo formula system of the present invention is scientific and reasonable, with synergistic effects among its components. It not only achieves gentle cleansing and good foaming effect, but also effectively nourishes hair follicles, inhibits hair loss, and promotes new hair growth. At the same time, it has excellent conditioning properties and a pleasant feel on the skin. Long-term use can significantly improve problems such as thinning hair, dryness, and hair loss.

[0019] It should be understood that the description in the Summary of the Invention is not intended to limit the key or essential features of the embodiments of the present invention, nor is it intended to restrict the scope of the invention. Other features of the invention will become readily apparent from the following description. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 This invention provides an anti-hair loss shampoo, comprising the following components: 65.56% water, 10.5% sodium lauryl ether sulfate, 2.8% ammonium lauryl sulfate, 1.2% water, 0.45% sodium lauryl sulfate, 1.155% cocoamide MEA, 0.075% trihydroxystearin, 0.05% propylene glycol, 0.867% phenoxyethanol, 0.734% sodium chloride, 1.08% polydimethylsiloxane, 0.018% tridecyl alcohol polyether-3, 0.018% tridecyl alcohol polyether-10, 0.009% benzyl alcohol, 0.091% ethylhexylglycerin, 0.000018% tocopherols, 0.0468% lauryl ether-16, and polyquaternium-52. 0.0312%, Methylparaben 0.0065%, Glycerin 0.12%, Butylene Glycol 0.84%, Platycladus orientalis leaf extract 0.36%, Zingiber officinale root extract 0.052%, Gentiana scabra root extract 0.002%, Polygonum multiflorum root extract 0.002%, Salvia miltiorrhiza root extract 0.002%, Panax ginseng root extract 0.002%, Gleditsia sinensis seed extract 0.001%, Cellulose gum 0.0025%, Disodium azelaate 0.096%, Arginine 0.004%, Pyridoxine 0.5%, Piroctone olamine 0.4%, Fragrance 0.4%, Behenamidopropyl dimethylamine 0.3%, Guar gum hydroxypropyltrimethylammonium chloride 0.273%, p-hydroxyacetophenone 0.3%, Citric acid 0.15%, Polyquaternium-10 0.137%, caramel color 0.04%, balance is water.

[0022] In this embodiment, sodium lauryl ether sulfate and ammonium lauryl sulfate serve as the main cleaning and foaming ingredients, effectively removing sebum and dirt from the scalp and hair surface, while also providing excellent foam richness and easy rinsing. The addition of appropriate amounts of cocamide MEA and trihydroxystearin further refines and stabilizes the foam, enhancing the smoothness of the hair after washing.

[0023] Polydimethylsiloxane, tridecyl alcohol polyether-3, and tridecyl alcohol polyether-10 form a uniformly distributed conditioning system that creates a flexible protective film on the hair surface, improving cuticle arrangement, thereby reducing combing friction and enhancing hair shine and smoothness. Disodium azelate and arginine can regulate the scalp microenvironment, promote keratinocyte health, and reduce scalp inflammation.

[0024] The formula contains extracts from various plants, including arborvitae leaves, ginseng, ginger, salvia miltiorrhiza, gentian, fleeceflower root, and small-fruited soapberry. These ingredients activate hair follicles, promote blood circulation, inhibit hair loss, and promote new hair growth. Arborvitae leaf extract, as the main anti-hair loss active agent, effectively improves the nutrient supply to hair follicles; ginger root extract and ginseng extract further enhance local microcirculation; fleeceflower root and salvia miltiorrhiza extracts nourish hair roots and delay hair follicle degeneration; and gentian root and small-fruited soapberry seed extracts cleanse the scalp and reduce sebum secretion.

[0025] Butylene glycol, glycerin, and cellulose gum together form a moisturizing system that maintains the shampoo's consistency and forms a moisturizing film after washing, slowing down scalp moisture evaporation. The preservative system uses a multi-component compound preservative, including phenoxyethanol, ethylhexylglycerin, methylparaben, and p-hydroxyacetophenone, to effectively prevent microbial growth in the formula, ensuring product stability and safety.

[0026] Furthermore, the synergistic use of piroctone olamine salt and pyridoxine provides both antibacterial and oil-controlling properties, inhibiting the growth of fungi that cause dandruff and improving dandruff and itching issues. Guar gum hydroxypropyltrimethylammonium chloride and polyquaternium-10 act as cationic conditioners, further enhancing hair smoothness and antistatic properties. Citric acid is used to adjust the pH of the system, making it slightly acidic and more compatible with the scalp environment. Caramel coloring is used to give the finished product a natural brown hue.

[0027] The anti-hair loss shampoo provided in this embodiment, through the synergistic effect of compound plant extracts and a mild surfactant system, not only achieves excellent cleaning, nourishing and anti-hair loss functions, but also ensures low irritation and a superior skin feel.

[0028] Example 2 A hair loss prevention shampoo comprises the following components: water 63.00%, sodium lauryl ether sulfate 11.2%, ammonium lauryl sulfate 3.0%, sodium lauryl sulfate 0.45%, cocamide MEA 1.10%, trihydroxystearin 0.075%, propylene glycol 0.05%, polydimethylsiloxane 1.25%, tridecyl alcohol polyether-3 0.018%, tridecyl alcohol polyether-10 0.018%, benzyl alcohol 0.009%, ethylhexylglycerin 0.091%, tocopherols 0.000018%, lauryl ether-16 0.0468%, and polyquaternium-52. 0.0312%, Methylparaben 0.0065%, Glycerin 0.12%, Butylene Glycol 0.90%, Platycladus orientalis leaf extract 0.40%, Zingiber officinale root extract 0.06%, Gentiana scabra root extract 0.0025%, Polygonum multiflorum root extract 0.0025%, Salvia miltiorrhiza root extract 0.0025%, Panax ginseng root extract 0.0025%, Gleditsia sinensis seed extract 0.001%, Disodium azelaate 0.10%, Arginine 0.004%, Pyridoxine 0.5%, Piroctone olamine 0.45%, Fragrance 0.35%, Behenamidopropyl dimethylamine 0.3%, Guar hydroxypropyltrimethylammonium chloride 0.273%, p-hydroxyacetophenone 0.3%, Citric acid 0.18%, Polyquaternium-10 0.15%, Caramel color 0.05%, Balance: Water. This formula demonstrates consistent performance in terms of cleansing power, foam texture, and anti-hair loss efficacy. By slightly increasing the proportion of sodium lauryl ether sulfate and active plant extracts, the shampoo's oil-removing ability and scalp conditioning effect are made more significant, making it suitable for oily hair and those with mild hair loss.

[0029] Example 3 An anti-hair loss shampoo comprises the following components: water 67.00%, sodium lauryl ether sulfate 9.8%, ammonium lauryl sulfate 2.5%, sodium lauryl sulfate 0.45%, cocamide MEA 1.20%, trihydroxystearin 0.075%, propylene glycol 0.05%, polydimethylsiloxane 0.95%, tridecyl alcohol polyether-3 0.018%, tridecyl alcohol polyether-10 0.018%, benzyl alcohol 0.009%, ethylhexylglycerin 0.091%, tocopherols 0.000018%, lauryl ether-16 0.0468%, and polyquaternium-52. 0.0312%, Methylparaben 0.0065%, Glycerin 0.12%, Butylene Glycol 0.80%, Platycladus orientalis leaf extract 0.32%, Zingiber officinale root extract 0.045%, Gentiana scabra root extract 0.0018%, Polygonum multiflorum root extract 0.0018%, Salvia miltiorrhiza root extract 0.0018%, Panax ginseng root extract 0.0018%, Gleditsia sinensis seed extract 0.001%, Disodium azelaate 0.085%, Arginine 0.004%, Pyridoxine 0.5%, Piroctone olamine 0.38%, Fragrance 0.42%, Behenamidopropyl dimethylamine 0.3%, Guar hydroxypropyltrimethylammonium chloride 0.273%, p-hydroxyacetophenone 0.3%, Citric acid 0.12%, Polyquaternium-10 0.13% caramel color, 0.035% water. This formula maintains good foaming and cleaning properties while reducing the active ingredient content, making the product gentler and suitable for dry scalps and people who wash their hair frequently. It reduces scalp irritation while maintaining anti-hair loss effects.

[0030] Comparative experiments and performance tests were conducted on the shampoos prepared in Examples 1 to 3. The experimental procedures are as follows: First, the required raw materials were weighed according to the formulation ratios of each embodiment. Deionized water was heated to 45°C, and anionic surfactant, amphoteric surfactant, and nonionic surfactant were added sequentially under stirring. After stirring until homogeneous, a basic system was obtained. Subsequently, conditioning agent, preservative, and natural plant extract were slowly added, maintaining a stirring rate of 300 rpm until the system was completely homogeneous. Finally, the pH of the system was adjusted to 5.5–6.0, and samples were taken after cooling to room temperature. The obtained sample was a brownish-yellow transparent liquid with good flowability.

[0031] In performance testing, 30 volunteers aged 25 to 45 years underwent hair cleaning and hair loss measurement tests. The experiment was divided into a control group (ordinary non-anti-hair loss shampoo) and an experimental group (Examples 1-3). The shampoo was used continuously for four weeks, three times a week, with approximately 10g used each time. By collecting the number of hairs shed during shampooing and recording the average value, the results showed that the average hair loss in Examples 1 to 3 was reduced by approximately 28%, 32%, and 35%, respectively, significantly better than the control group (reduction of less than 10%).

[0032] To verify the cleaning performance, a standard silica oil stain washing test was conducted to determine the detergency of different samples. The test results showed that the average detergency of Examples 1 to 3 were 91.3%, 92.5%, and 93.0%, respectively, all higher than that of ordinary shampoos (87.5%). This indicates that the formulation of the present invention maintains excellent cleaning ability without reducing foaming and detergency effects due to the addition of anti-hair loss components.

[0033] Meanwhile, a human patch test was conducted to assess skin irritation. The shampoo was diluted 10 times and applied to the skin surface of the volunteers' forearms. Skin reactions were observed 24 hours after application. The results showed that no irritation reactions such as erythema or edema occurred in the samples of the three embodiments, and they were determined to be non-irritating.

[0034] The above experimental results show that the anti-hair loss shampoo provided by the present invention can effectively reduce hair loss during use, has good cleaning performance, and is gentle and non-irritating to the skin, thus possessing high practicality and safety.

[0035] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
