Description

Technical Field

[0001] This invention relates to the field of daily chemical products and hair care technology, specifically to a no-rinse spray and its preparation method, which is composed of pure natural plant extracts and has multiple effects such as promoting the natural blackening of gray hair, stimulating hair growth, and nourishing hair. It can simultaneously promote the natural blackening of gray hair, activate hair follicles, promote hair growth, nourish the scalp and hair, and is convenient to use. Background Technology

[0002] Currently, with increasing life pressures and an aging population, the number of people with gray hair is rising, and gray hair and hair loss are increasingly coexisting and showing a trend towards affecting younger people. Current solutions on the market have significant limitations; hair dyeing products are mostly chemically synthesized, relying on oxidants and dye precursors to penetrate the hair shaft for coloring. These products generally suffer from the following significant drawbacks: 1. Chemical hair dyes: These use aniline derivatives (such as p-phenylenediamine PPD), resorcinol, ammonia, and oxidizing agents (such as hydrogen peroxide) to penetrate and color the hair. They only physically cover gray hair, offering only a temporary solution and failing to address the root cause. They cannot improve the melanin production environment in hair follicles, resulting in new gray hair. Furthermore, they easily cause scalp allergies and irritation, and long-term use carries potential cancer risks. The chemical components and oxidation process damage keratin in the scalp, leading to dry, brittle hair and severely damaging hair quality. They are also cumbersome to use: requiring mixing, application, waiting, and rinsing, making the process complex.

[0003] 2. Chemical hair growth products: The main ingredients, such as minoxidil and finasteride, may have some therapeutic effect, but they may be accompanied by side effects such as scalp irritation and itching, contact dermatitis, hirsutism, and sexual dysfunction caused by oral medications, and they cannot solve the problem of gray hair.

[0004] 3. Existing plant-based products: Most plant-based hair dyes are multifunctional but limited in function, or lack sufficient coloring power and durability, and are cumbersome to use and still require rinsing; while some plant-based anti-hair loss shampoos, due to their rinsing characteristics, have short contact time with active ingredients, making it difficult to effectively penetrate hair follicles and exert a deep effect. They fail to meet consumers' urgent need for safe, effective, portable, and multifunctional integrated products.

[0005] Therefore, the market urgently needs a natural external solution and natural gray hair to black hair product that can simultaneously nourish hair follicle melanocytes from the root, restore melanin synthesis, effectively activate dormant hair follicles, prolong the hair growth phase, is absolutely safe and harmless, and integrates the functions of turning gray hair black and promoting hair growth and strengthening hair.

[0068] 2. In a clean mixing tank, add the measured amount of deionized water and natural vegetable glycerin, turn on the stirrer and stir at a speed of 200-300 r / min for 5-10 minutes to mix them evenly.

[0069] 3. While stirring, slowly add the following extracts in sequence: Polygonum multiflorum extract, Platycladus orientalis leaf extract, black sesame extract, Angelica sinensis extract, ginger extract, Ligusticum chuanxiong extract, Vitex trifolia extract, and licorice extract.

[0070] 4. After adding the ingredients, adjust the speed to 300-400 rpm and stir continuously for 40-60 minutes to ensure that all plant extracts are completely dissolved and dispersed to form a homogeneous system.

[0071] 5. Add clove extract and continue stirring for 15-20 minutes.

[0072] 6. The resulting mixture was filtered through a 0.45 μm microporous membrane to obtain a clear and stable liquid.

[0073] 7. Fill the filtrate into a light-proof spray bottle under sealed and light-proof conditions, and seal it to obtain the finished product.

[0074] • Effects: Focuses on intensive care for stubborn gray hair problems.

[0075] This formula is the key ingredient in the entire product line, specifically designed to tackle the problem of gray hair.

[0076] Analysis of beneficial effects I. Core Positioning: Precise targeting, powerfully promoting melanin production. • Target users: Users whose gray hair problem is very significant and concentrated, and is their primary concern; people who hope to achieve faster and more effective results in turning gray hair black after using the basic product.

[0077] Design concept: Focus on key ingredients for breakthrough. By adjusting the ratio of key ingredients, formula resources are tilted towards the "black hair" pathway.

[0078] II. Outstanding Beneficial Effects and Formulation Logic 1. [Core Nourishment, Upgraded Dosage] (Strengthening the Hair Darkening Pathway) • Formulation logic: The dosage of Polygonum multiflorum extract (7%) and black sesame extract (4.5%) has been significantly increased. These two are core ingredients for nourishing hair follicles and promoting melanin synthesis.

[0079] • Beneficial effects: It provides a more abundant and intensive supply of nutrients to the melanocytes in the hair follicles, just like providing double the raw materials to the factory (hair follicles), which can more powerfully activate and support the melanin synthesis mechanism, accelerating the process of turning gray hair black from the source.

[0080] 2. [Promotes blood circulation and penetration, ensuring efficient delivery] (Ensuring nutrients reach their destination efficiently) • Formulation logic: The dosage of Angelica sinensis extract (3%) and ginger extract (2.5%) was increased simultaneously. They are key members of the "blood-activating and penetration-enhancing unit".

[0081] • Beneficial effects: This not only enhances the effect of improving scalp microcirculation, but more importantly, it ensures that the doubled investment of "black hair" nutrients (Polygonum multiflorum and black sesame) can be delivered to the hair follicle target more efficiently, solving the problem of "having food but not being able to deliver it", thus enabling the targeted effect to be achieved.

[0082] 3. [Streamline growth, focus on core business] (Strategic adjustment) • Formulation logic: The proportions of Vitex trifolia extract (1.5%) and Glycyrrhiza uralensis extract (0.5%) were appropriately reduced. Vitex trifolia is mainly responsible for activating hair follicles and promoting hair growth, while Glycyrrhiza uralensis mainly focuses on anti-inflammatory and stabilizing effects.

[0083] • Beneficial Effects: This is a very sophisticated strategic adjustment. It doesn't weaken the hair growth and stabilization functions, but rather, given the limited total amount of formula, allocates more valuable resources to the "turning black" task. This ensures that the formula's power is concentrated and its target is clear, avoiding the dispersion of firepower in an attempt to do everything. The basic functions of hair growth and stabilization still exist, but primarily serve to create a healthy foundation environment for black hair growth.

[0084] III. Summary and Expected Results This formula (Very Effective Hair Darkening Formula) is a specialized product designed for specific needs. It employs a three-pronged strategy of "enhancing hair-darkening nutrition + improving blood circulation and penetration + streamlining auxiliary functions" to achieve a intensive attack on gray hair problems.

[0085] Expected results: Compared to the basic maintenance type, users can expect to observe the following: • Faster regrowth: The cycle from the roots of gray hair turning gray to black may be shorter.

[0086] • More noticeable area of ​​graying: The improvement may be more obvious for stubborn and concentrated areas of gray hair.

[0087] • Excellent hair loss prevention and hair strengthening effect: Its hair loss prevention effect remains strong because it retains the complete "blood circulation and penetration promotion" system, which can effectively strengthen hair roots.

[0088] Simply put, if gray hair is considered the primary enemy, then this product is a "precision weapon" tailor-made for it.

[0089] Example 3: Natural preservative and fragrance-enhancing hair growth formula (with excellent hair darkening and hair growth functions) • Formula: (weight g / 100g) Polygonum multiflorum extract: 6g • Arborvitae leaf extract: 5g Black sesame extract: 4g • Vitex trifolia extract: 2.5g Angelica extract: 3g • Ginger extract: 2g • Ligusticum chuanxiong extract: 2g • Licorice extract: 1.5g • Natural vegetable glycerin: 3.5g Clove extract: 0.2g • Deionized water: Add to 100g • Preparation method: 1. Weigh each component precisely according to the above proportions.

[0090] 2. In a clean mixing tank, add the measured amount of deionized water and natural vegetable glycerin, turn on the stirrer and stir at a speed of 200-300 r / min for 5-10 minutes to mix them evenly.

[0091] 3. While stirring, slowly add the following extracts in sequence: Polygonum multiflorum extract, Platycladus orientalis leaf extract, black sesame extract, Angelica sinensis extract, ginger extract, Ligusticum chuanxiong extract, Vitex trifolia extract, and licorice extract.

[0092] 4. After adding the ingredients, adjust the speed to 300-400 rpm and stir continuously for 40-60 minutes to ensure that all plant extracts are completely dissolved and dispersed to form a homogeneous system.

[0093] 5. Add clove extract and continue stirring for 15-20 minutes.

[0094] 6. The resulting mixture was filtered through a 0.45 μm microporous membrane to obtain a clear and stable liquid.

[0095] 7. Fill the filtrate into a light-proof spray bottle under sealed and light-proof conditions, and seal it to obtain the finished product.

[0096] Effects: This product has excellent effects in both turning hair black and promoting hair growth.

[0097] This formula (a combination of natural preservatives, flavor enhancers, and growth promoters) is the "all-around trump card" and "performance benchmark" in the entire product system.

[0098] Beneficial effects

[0099] I. Core Positioning: Balanced and versatile, pursuing the ultimate synergy between turning gray hair black and promoting hair growth and strengthening hair.

[0100] • Target users: Users facing both significant gray hair and noticeable hair loss; users seeking the most comprehensive and powerful results from a single product; users who want to take the results to the next level after using the basic version.

[0101] Design philosophy: No specialization, aiming for the highest overall score. This formula does not have an extreme bias towards "turning hair black" like Example 2, nor does it weaken any function. Instead, through a balanced and sufficient ratio of ingredients, it keeps both the "blackening hair" and "hair growth" systems in optimal working condition, producing the strongest synergistic effect.

[0102] II. Outstanding Beneficial Effects and Formulation Logic 1. Both the hair-darkening and hair-growth systems are in a "high-power" state. • Black hair system: The combination of Polygonum multiflorum (6%) + Platycladus orientalis leaf (5%) + black sesame (4%) provides a strong and stable supply of nutrients, which is sufficient to continuously support the large-scale synthesis of melanin.

[0103] Hair growth system: The dosage of Vitex trifolia (2.5%) is the highest in all embodiments, which means that the "activation" signal to hair follicles is the strongest; combined with sufficient Ligusticum chuanxiong (2%) and Angelica sinensis (3%), the effect of promoting blood circulation and removing blood stasis is significant.

[0104] • Beneficial effects: This product can simultaneously and efficiently address the two major problems of gray hair and hair loss, eliminating the need for users to choose between "turning gray hair black first or starting hair growth first," achieving a true "two-pronged approach."

[0105] 2. [The deep synergistic effect has reached its peak] The brilliance of this formula lies in the fact that it allows all the synergistic effects mentioned earlier to be fully realized: • Maximizing the synergistic effect of “nourishing and invigorating blood”: Ample hair-darkening nutrients (such as Polygonum multiflorum) meet the powerful blood-invigorating and penetration-promoting forces (Angelica sinensis, Ligusticum chuanxiong, and ginger), ensuring the efficient absorption and utilization of nutrients.

[0106] • Optimized “Activation-Stability” Synergy: The strongest hair follicle activator (Vitex trifolia) works in a fully anti-inflammatory and soothing scalp environment (1.5% licorice), ensuring that the hair growth process is both efficient and gentle, avoiding the risk of “being unable to tolerate the supplement” or stimulation.

[0107] 3. [Comprehensive scalp environment optimization] • Formula rationale: The licorice extract content is 1.5%, the highest among all formulas except the top-tier one. This reflects the formula's emphasis on the "healthy foundation of the scalp."

[0108] • Beneficial effects: It can more effectively soothe scalp inflammation and reduce itching, creating a more stable and healthier growth environment for hair follicles. This not only improves the hair growth and darkening effect but also directly enhances comfort during use.

[0109] III. Summary and Expected Results This formula (a combination of natural preservatives and flavor enhancers for promoting hair growth) is the "complete version" of this invention. It represents the highest performance level that the core formula system can achieve without the addition of external ingredients such as ginseng and Ganoderma lucidum.

[0110] Expected results: Users can expect to observe comprehensive and robust improvements: • In terms of preventing hair loss and promoting hair growth: The amount of hair loss is reduced rapidly, and the new growth of fine hairs and stray hairs can be clearly felt in a short period of time (1-2 months).

[0111] Regarding the reversal of gray hair to black: Gray hair gradually and steadily turns from the roots to gray and eventually black.

[0112] • Overall hair quality and scalp health: Problems such as oily scalp and itching are effectively controlled, and the overall hair quality feels stronger and healthier.

[0113] Simply put, if you want a product that delivers the best results in both "reversing blackening" and "hair regrowth," then this product is undoubtedly the top choice. It's a perfect combination of effectiveness and balance.

[0118] 5. Add clove extract and continue stirring for 15-20 minutes.

[0119] 6. The resulting mixture was filtered through a 0.45 μm microporous membrane to obtain a clear and stable liquid.

[0120] 7. Fill the filtrate into a light-proof spray bottle under sealed and light-proof conditions, and seal it to obtain the finished product.

[0121] This formula also falls under the category of "natural preservative-enhancing and fragrance-enhancing comprehensive hair growth formula" as defined in the patent.

[0122] Its core efficacy is completely consistent with the original "natural preservative and flavor enhancer" formula. Its characteristic is that it uses cinnamon extract as a natural preservative and flavor enhancer, and uses a dosage of 0.2g.

[0123] I. Product Type Positioning Core positioning: Natural, preservative-preservative, and fragrance-enhancing hair growth formula (warm fragrance version) This is a version based on the "All-Around Formula," which, through the use of cinnamon extract, offers a differentiated sensory experience while maintaining its comprehensive and outstanding efficacy. It is aimed at users who face significant gray hair and hair loss issues and prefer a warm, sweet scent.

[0124] II. Outstanding Beneficial Effects This product first and foremost possesses all the core beneficial effects of a "comprehensive hair growth" treatment: 1. Both the hair-darkening and hair-growth systems are in a "high-power" state. • Black hair system: The combination of Polygonum multiflorum (6%) + Platycladus orientalis leaf (5%) + black sesame (4%) provides a strong and stable supply of nutrients, which is sufficient to continuously support the large-scale synthesis of melanin.

[0125] Hair growth system: The dosage of Vitex trifolia (2.5%) is the highest in all embodiments, which means that the "activation" signal to hair follicles is the strongest; combined with sufficient Ligusticum chuanxiong (2%) and Angelica sinensis (3%), the effect of promoting blood circulation and removing blood stasis is significant.

[0126] • Beneficial effects: This allows the product to simultaneously and effectively address both gray hair and hair loss, achieving a true "two-pronged approach".

[0127] 2. [The deep synergistic effect has reached its peak] The brilliance of this formula lies in the fact that it allows all the synergistic effects mentioned earlier to be fully realized: • Maximizing the synergistic effect of “nourishing and invigorating blood”: Ample hair-darkening nutrients (such as Polygonum multiflorum) meet the powerful blood-invigorating and penetration-promoting forces (Angelica sinensis, Ligusticum chuanxiong, and ginger), ensuring the efficient absorption and utilization of nutrients.

[0128] • Optimized “Activation-Stability” Synergy: The strongest hair follicle activator (Vitex trifolia) works in a fully anti-inflammatory and soothing scalp environment (1.5% licorice), ensuring that the hair growth process is both efficient and gentle.

[0129] In addition, this product offers further benefits due to the use of 0.2g of cinnamon extract: 3. [A rich and warm sensory experience] • Increasing the amount of cinnamon extract to 0.2g makes its warm, sweet aroma more intense and long-lasting.

[0130] This intense warmth provides a more significant soothing and relaxing effect, making it an excellent experience for users who want to relieve stress through the care process.

[0131] 4. [Potential auxiliary effects in promoting circulation and preventing corrosion] • The warming properties of cinnamon may synergize more significantly with blood-activating components, helping to enhance scalp blood circulation.

[0132] The dosage of 0.2g also means that its natural preservative effect is stronger, which helps the product maintain stability for a longer period of time.

[0133] III. Summary This "comprehensive hair growth" formula, containing 0.2g of cinnamon extract, is a combination of "all-around champion" and "top-notch experience".

[0134] It not only strives to achieve the best results in both "turning gray hair black" and "promoting hair growth and strengthening hair", but also provides users with an extremely pleasant and relaxing experience through its rich and warm cinnamon aroma.

[0165] Effects: This product has a broader spectrum of preservative effects and a richer aroma.

[0166] This formula can be considered the "ultimate supreme version" or "complete flagship version" in the entire patent system.

[0167] It is not a simple repetition of any previous single embodiment, but rather a fusion of all our best design concepts, which can be defined as the "Supreme All-Round Type".

[0168] I. Product Type Positioning Core Positioning: Supreme All-Round Model (Ultimate Flagship) This formula achieves a perfect fusion of three top-tier strategies: 1. [Comprehensive Foundation for Hair Growth]: It adopts the balanced and high-energy formula of "Example 3" to ensure that both the hair growth and blackening systems are in optimal condition.

[0169] 2. [Top-tier nourishing core essence]: Contains high doses of ginseng (2%) and reishi mushroom (2%) to provide the deepest energy nourishment and system stabilization.

[0170] 3. [A premium experience with compound preservative and fragrance enhancement]: High doses of clove (0.2%) and cinnamon (0.2%) are used to achieve ultimate preservative stability and a luxurious compound fragrance experience.

[0171] II. Outstanding Beneficial Effects This product represents the culmination of all its beneficial effects and signifies the pinnacle of this invention: 1.

[0176] III. Summary This formula is undoubtedly the "king's choice".

[0177] It has no weaknesses and surpasses everything else. Whether it's the severity of gray hair, the troubles of hair loss, or the ultimate pursuit of product quality, user experience, and physical and mental well-being, this "supreme all-rounder" product can provide an impeccable solution.

[0178] Simply put, if you're looking for the ultimate results and experience in hair care, without any compromises, then this is the final answer you can find. It represents the pinnacle of this project's technological development and market understanding.

[0179] • How to use and effects: Use morning and evening. Spray onto the scalp, gray hair, and thinning areas, and massage until absorbed. It is expected that after 1-2 months of continuous use, hair loss will be significantly reduced and hair roots will be stronger. After 3-4 months of use, new fine hairs will appear, and gray hair will gradually turn gray and then black from the roots.

[0180] VI. Compared with the prior art, the present invention has the following outstanding and unexpected advantages, which stem from its unique all-natural formulation design and multi-target synergistic mechanism: I. Fundamental Advantage: From "Surface Cover-up" to "Source Repair" 1. Treat the root cause, not just the symptoms: • Current technology: Chemical hair dyes (such as products containing p-phenylenediamine PPD) generate color on the hair shaft through an oxidation reaction, only covering gray hair. New hair roots remain white, requiring frequent touch-ups.

[0181] This invention utilizes active ingredients such as Polygonum multiflorum and black sesame to penetrate hair follicles, providing nutrition to melanocytes and restoring their ability to synthesize melanin from the root, thus enabling gray hair to naturally turn black from the hair root, and new hair growth to also be black, with long-lasting and healthy effects.

[0182] Dual benefits, one-stop solution: • Current technology: Market products have extremely limited functionality. Hair dyeing products do not promote hair growth, and hair growth products do not darken hair. If a user has both needs, they must purchase and use two different products, which is cumbersome, costly, and their ingredients may conflict with each other.

[0183] This invention innovatively integrates the functions of "blackening hair" and "hair growth". Through the synergy of nourishing units (Polygonum multiflorum, black sesame, and Platycladus orientalis leaves) and blood-activating units (Angelica sinensis, Ligusticum chuanxiong, ginger, and Vitex trifolia), it simultaneously solves the two major problems of melanin production in hair follicles and activation of hair matrix cells, providing a one-stop solution.

[0184] II. Safety Advantages: Absolute Safety and Extreme Gentleness 1. 100% natural source, eliminating health risks: • Current technology: Chemical hair dyes are known to have sensitizing risks (e.g., PPD is a common allergen) and even have potential carcinogenicity controversies. Chemical hair dyes (such as minoxidil) may cause side effects such as scalp itching and increased heart rate.

[0185] This invention: All ingredients are derived from natural plant extracts and contain absolutely no harmful chemically synthesized components such as aniline derivatives, heavy metals, hormones, strong oxidants, or alcohol. This fundamentally eliminates the risk of allergies, irritation, and potential toxic side effects, making it safe for even those with sensitive scalps and long-term users.

[0186] III. User Experience Advantages: Extreme Convenience and Multiple Maintenance Features 1. The revolutionary experience of "one spray, no washing required": • Existing technology: The process of using traditional hair dyeing and hair growth products is extremely cumbersome (mixing, applying, waiting, washing), taking tens of minutes to several hours, and easily staining clothes and skin.

[0187] This invention utilizes a spray formulation, requiring only a few sprays and a simple massage daily, eliminating the need for rinsing. This not only saves a significant amount of time but, more importantly, ensures long-lasting contact and continuous penetration of the active ingredients into the scalp, greatly enhancing effectiveness and user experience.

[0188] Comprehensive care to improve hair quality: • Current technology: Chemical hair dyes severely damage hair, leading to dryness and breakage. Many hair growth products focus on stimulation and lack sufficient conditioning function.

[0189] This invention, while achieving hair darkening and hair regrowth, also contains ingredients such as glycerin and licorice that deeply moisturize, soothe inflammation, and strengthen hair roots, making hair not only thicker and darker, but also stronger and shinier, achieving true all-round care.

[0190] IV. Technical Mechanism Advantages: Synergistic Effect of Multiple Pathways 1. Synergistic effect of multiple targets, with an effect greater than the sum of its parts (1+1>2): • Current technology: Most products have a single mechanism of action. For example, minoxidil mainly dilates blood vessels, while finasteride inhibits androgens.

[0191] This invention's remarkable effects do not stem from a simple accumulation of ingredients, but rather from a carefully designed synergistic system. • Nourishing + Blood Circulation + Penetration Enhancement: Polygonum multiflorum / black sesame (nourishing) + Angelica sinensis / Ligusticum chuanxiong (blood circulation enhancement) + ginger (penetration enhancement) ensure that nutrients can be efficiently delivered to the target hair follicles.

[0192] Activation + Stabilization: Vitex trifolia (activates hair follicles) + licorice (anti-inflammatory and stabilizing), while stimulating hair follicle regeneration, creates a healthy, non-inflammatory growth environment for them.

[0193] This multi-pathway, multi-target mechanism of action produces unexpected synergistic effects, and its overall efficacy is far superior to any single-component or single-function product.

[0194] Summary and Comparison Table Comparison with existing technologies (chemical hair dyes / hair growth agents) | This invention (natural multifunctional spray) Mechanism of action: Surface oxidation and staining or stimulation through a single pathway. Nourishing hair follicles at the source, with synergistic activation of multiple targets. The core function is singular (either dyeing or hair growth). Gray hair to black + hair growth and strengthening + conditioning, one... bodyization.

[0195] There are potential safety risks, including sensitization, irritation, and other health risks. 100% natural, absolutely safe, and without any side effects. use.

[0196] The traditional method involves cumbersome processes such as mixing, waiting, and rinsing. This new product is ready to use with a single spray, requires no rinsing, and is extremely convenient.

[0197] Persistent but temporary coverage requires frequent use. Addressing the root cause leads to naturally longer-lasting results.

[0198] Hair quality often damages hair, leading to dryness. Improving hair quality makes hair strong and shiny.

[0199] In summary, this invention is not a simple improvement on existing technologies, but a disruptive innovation in concept, formulation, mechanism, and experience. It successfully resolves the contradiction between "safety and effectiveness" and "single function and comprehensive needs" that has plagued the industry for many years, and provides an unprecedented solution.

[0200] Although the present invention has been described in detail above with general descriptions, specific embodiments and experiments, the present invention is not limited to the above embodiments. Those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, all of which fall within the scope of protection claimed by the present invention.
