COMPOSITION AND KIT FOR POST-HAIR TRANSPLANT TREATMENT Technological sector of invention

[001] The present invention belongs to the sector of topical products and supplements aimed at hair care after transplantation, and refers, more specifically, to a kit composed of formulations developed to cleanse, hydrate, soothe and protect the newly transplanted scalp, with compositions adjusted in concentration, pH and texture to promote healing, reduce inflammation and stimulate healthy hair growth. State of the art

[002] The state of the art aimed at accelerating and optimizing scalp recovery after hair transplantation brings together resources that are already known, but still dispersed, with the objective of reducing inflammation, promoting healing and, in later stages, stimulating the healthy growth of transplanted follicles. In clinical practice and on the market, partial solutions are found, such as low-aggressiveness cleansing agents to remove scabs without displacing grafts, antiseptics in moderate concentrations for microbiological control, soothing and anti-inflammatory complexes of botanical origin — such as aloe vera, witch hazel, chamomile, centella asiatica, calendula and propolis — and humectants / emollients such as glycerin and panthenol, aimed at restoring the skin barrier and reducing itching.

[003] In parallel, delivery vehicles and technologies are emerging that improve the tolerability and penetration of active ingredients, including gentle rinse foams that minimize friction, film-forming aqueous sprays that provide frequent hydration without creating heavy occlusion, as well as gels and serums with bioadhesive polymers, liposomes, and polymeric systems capable of delivering sensitive active ingredients. There are also complementary approaches performed in the office, such as the application of low-level light (LED / LLLT) and protocols with growth factors or platelet-rich plasma (PRP), applied in specific phases of recovery.

[004] Despite these advances, an important gap persists: most available products are generic and targeted only at sensitive scalps, without considering the specific demands of the post-transplant period. In this phase, conditions such as microinflammation, fragility of the skin barrier, the need for rapid re-epithelialization, and rigorous contamination control coexist. Subsequently, the priority shifts to follicular maturation, focusing on neoangiogenesis and the metabolic support of growing hair follicles.

[005] Another critical point is that many products do not have transparent formulations, nor do they specify concentrations or pharmaceutical justifications adapted to the climate, phototypes, and microbiome characteristic of the Brazilian population. Furthermore, there is a lack of efficacy and safety studies conducted in the national context, with relevant clinical outcomes such as time to crusting, reduction of itching and erythema, transepidermal water loss (TEWL), patient satisfaction, and objective parameters of hair density and thickness.

[006] In summary, although there are recognized mild shampoos and hair care lines, these alternatives do not constitute an integrated and sequenced protocol that specifically addresses the needs of the newly transplanted scalp. The open technological space lies precisely in the creation and validation of a complete regimen, with vehicles and active ingredients coordinated by phase, clear dosage, and technical-scientific support adapted to the Brazilian reality. New features and objectives of the invention.

[007] In this context, the present invention introduces as its main differentiating factor the creation of customized formulations, developed with carefully selected active ingredients adjusted to meet the specific needs of the scalp in the post-hair transplant period. The concentrations of each component were calibrated to maximize clinical efficacy, considering factors such as tolerability, safety, and functional performance in newly transplanted tissue. Unlike generic hair care products, this solution was conceived as a complete protocol, in which each composition plays a complementary role, integrating seamlessly. Petition 870260056154, dated 10 / 06 / 2026, page 6 / 24 3 / 6 sequenced to accelerate recovery, reduce inflammation, promote healing and foster healthy hair growth.

[008] The Post-Hair Transplant Kit initially consists of three products that, together, cover the main stages of post-procedure care. The Post-Procedure Hair Foam has a light foaming base and is formulated to gently cleanse without irritating the scalp, incorporating anti-inflammatory and healing active ingredients that help maintain a clean environment conducive to regeneration. The Post-Procedure Hair Emollient acts as a moisturizing and regenerating lotion, applied to maintain moisture and restore skin integrity, preventing dryness and promoting tissue repair. The Post-Procedure Soothing Spray is a topical solution with soothing, refreshing, and antibacterial active ingredients, intended for daily use to relieve discomfort, control the local microbiota, and reinforce hydration throughout the day.

[009] All products comprising the kit were developed with attention to compatibility with the post-surgical period, featuring adapted textures, balanced pH, and a composition free of irritating agents or agents potentially harmful to follicles in the fixation phase. In this way, the invention offers an integrated and specialized regimen capable of directly addressing the demands of the newly transplanted scalp, filling an important gap in clinical practice and the hair care market. Detailed description of the invention.

[010] The kit is used to promote the recovery and care of the scalp and newly implanted hair follicles, particularly to accelerate healing, reduce inflammation, preserve hydration and promote healthy hair growth in a post-hair transplant treatment method, including gentle cleansing, deep hydration, relief of discomfort and protection against external agents, in a sequential and integrated manner.

[011] The topical cosmetic composition with a foaming base for scalp cleansing consists of 0.12 to 0.6% chlorhexidine digluconate, PCA of Petition 870260056154, dated 10 / 06 / 2026, page 7 / 24 4 / 6 sodium 1 to 3%, phenoxyethanol with caprylyl glycol 0.5%, sweet orange essential oil 0.3 to 1.0%, sodium lauryl ether sulfate succinate 10 to 25%, polysorbate 80 1 to 3%, panthenol 1 to 2.5%, butylated hydroxytoluene 0.1 to 0.5%, cocamidopropyl betaine 2 to 5%, glycerin 2 to 5% and water in QSP.

[012] The topical cosmetic composition in aqueous solution for a calming and protective effect on the scalp is composed of Saccharomyces cerevisiae yeast extract 0.5 to 1.5%, witch hazel leaf extract 0.5 to 1.5%, chamomile flower extract 0.5 to 1.5%, propolis extract 0.5 to 1.5%, panthenol 1 to 2.5%, phenoxyethanol with caprylyl glycol 0.5%, aloe vera extract 1 to 2.5%, centella asiatica extract 1 to 2.5%, calendula flower extract 1 to 2.5%, glycerin 2 to 4%, propanediol 1 to 2.5%, black elderflower extract with glycerin, citric acid, sodium benzoate and potassium sorbate 0.5 to 1.5% spent grain wax with shea butter extract and 0.5 to 1.5% argan oil, 0.3 to 1.0% sweet orange essential oil and water in QSP.

[013] The topical cosmetic composition in the form of an emollient lotion for moisturizing and regenerating the scalp consists of panthenol 1 to 2.5%, shea butter 2 to 4%, sodium PCA 1%, aloe vera extract 1 to 2.5%, acryloyldimethyltaurate / VP ammonium copolymer 1 to 2.5%, phenoxyethanol with caprylyl glycol 0.5%, glycerin 3 to 6%, caprylic / capric triglycerides 2 to 4%, allantoin 0.5 to 1.5%, cetearyl olivate and sorbitan olivate 0.5 to 1.0%, sweet orange essential oil 0.3 to 0.88% and water in QSP.

[014] The kit comprises three compositions: a topical cosmetic composition with a foaming base for scalp cleansing; a topical cosmetic composition in aqueous solution for a soothing and protective effect on the scalp; and a topical cosmetic composition in the form of an emollient lotion for hydration and regeneration of the scalp. Each composition is packaged individually.

[015] The kit formulations have an adjusted pH to ensure compatibility with the scalp in the post-hair transplant period, preserving skin integrity and the stability of the active ingredients. The topical cosmetic composition of Petition 870260056154, dated 10 / 06 / 2026, page 8 / 24 The 5 / 6 foaming base for cleansing (hair foam) has a pH between 5.5 and 5.8, a slightly acidic range that approximates the physiological pH of the skin, promoting gentle cleansing without compromising the skin barrier. The topical cosmetic composition in aqueous solution (soothing spray) has a pH between 5.2 and 5.4, ideal for providing a calming and refreshing effect, aligned with the natural pH of the scalp and promoting comfort during daily use. The topical cosmetic composition in lotion form (hair emollient) has a pH between 6.5 and 6.7, slightly higher, suitable for optimizing the action of the moisturizing and regenerating components, while maintaining skin tolerance.

[016] After a hair transplant, the scalp goes through a recovery period in which the skin and transplanted follicles are more sensitive and susceptible to inflammation, dryness, and discomfort. The coordinated use of products such as hair foam, soothing spray, and hair emollient aims to protect the treated area, promote healing, maintain adequate hydration, and provide more comfort to the patient during the recovery process.

[017] The post-procedure hair foam is formulated to gently cleanse the donor and recipient areas, removing impurities and residue without damaging the scalp. Its components help control microbial proliferation and maintain moisture balance, promoting a clean environment for healing. Application should be done daily, using a small amount on the indicated areas, followed by a gentle massage to avoid displacement of the follicles, finishing with a thorough rinse.

[018] The soothing hair spray acts directly to relieve the sensation of discomfort, itching and irritation that may arise after surgery. Its formulation combines plant extracts and moisturizing agents that reduce redness, soothe the skin and help maintain the skin barrier. Use by spraying the product onto the scalp two to three times a day, allowing the active ingredients to work without the need for rinsing, keeping the scalp constantly hydrated and comforted.

[019] Post-procedure hair emollient has the function of reinforcing the hydration and elasticity of the scalp skin, preventing dryness and promoting better skin regeneration. Its nourishing ingredients help restore the hydrolipidic film, improving the feeling of softness and protecting against external aggressions. Application should be done according to professional guidance, depositing a small amount on the indicated area and spreading gently to avoid excessive friction.

[020] This sequence — gentle cleansing with the foam, frequent relief and hydration with the soothing spray, and intensive nourishment with the emollient — promotes skin recovery, protects transplanted follicles, and contributes to a safer and more comfortable result after hair transplantation.
