US-20260124124-A1 - Hair Treatment Compositions

Abstract

Hair treatment compositions are disclosed. In some embodiments, the composition can include a first fraction of lipid vesicles encapsulating a first material and a second fraction of lipid vesicles encapsulating a second, different material. In some embodiments, the first material is a stimulant material, such as caffeine or green tea catechins, and the second material is a botanical bioactive material. The lipid vesicles can be plant-derived extracellular vesicles. In some embodiments, the composition comprises a base material with a non-encapsulated stimulant material and lipid vesicles that encapsulate a botanical bioactive material. The composition can also include three distinct carrier systems: lipid vesicles, liposomes, and ceramide complexes, each encapsulating a different bioactive material. These compositions can be formulated into products such as serums, masks, shampoos, or conditioners, which can be part of a multi-product hair care system.

Description

TECHNICAL FIELD This relates to hair treatment compositions and, more particularly, to hair treatment compositions including lipid vesicles for delivering bioactive materials. BACKGROUND Hair loss and thinning affect a significant portion of the population, with causes ranging from genetic factors to stress-induced conditions. Conventional hair care products have attempted to address these concerns through various approaches, including topical application of active ingredients intended to stimulate follicles and improve scalp health. Unfortunately, these attempts have not been entirely or even partially successful. GENERAL DESCRIPTION A hair treatment composition can include one or more delivery systems to improve the stability and targeted delivery of bioactive materials to the hair and scalp. The delivery systems can include lipid vesicles, liposomes, and/or ceramide complexes that encapsulate the same or different bioactive materials. By encapsulating these materials, the compositions can protect them from degradation and more effectively address issues such as hair loss and thinning. A hair treatment composition can include a first fraction of lipid vesicles encapsulating a first material and a second fraction of lipid vesicles encapsulating a second, different material. The lipid vesicles in one or both fractions can be plant-derived extracellular vesicles, such as exosomes. The first material can be a stimulant material, such as a polyphenol including caffeine and/or epigallocatechin gallate (EGCG), while the second material can be a botanical bioactive material, such as one or more Ayurvedic botanical extracts. In some configurations, a hair treatment composition can include a base material and lipid vesicles that encapsulate a botanical bioactive material. The base material can also include a non-encapsulated stimulant material, such as caffeine and/or a green tea catechin, dissolved directly within it. This approach allows for a split-release effect, providing both an immediate topical impact from the non-encapsulated stimulant and a sustained, targeted delivery of the encapsulated botanical material. A hair treatment composition can also be formulated to include three distinct carrier systems. For example, a single composition can include lipid vesicles encapsulating a first bioactive material, liposomes encapsulating a second bioactive material, and ceramide complexes encapsulating a third bioactive material. Each carrier system can be selected to deliver a different type of bioactive material, such as various botanical materials including curcumin and/or Ayurvedic extracts. The hair treatment compositions can be formulated into various product forms, such as a daily serum, a booster mask, a shampoo, a conditioner, and/or a leave-in composition. These individual products can be designed to work together synergistically as part of a multi-product hair care system. For example, a booster mask can be formulated to provide prolonged follicular availability of its encapsulated botanical bioactives for at least 8 hours following application. A shampoo can be formulated with a sulfate-free surfactant system and a pH of approximately 4.0 to 6.0 to gently cleanse the scalp. In some configurations, the shampoo base comprises a rice water extract infused with one or more amino acids to prepare the scalp and hair for subsequent treatments. In one embodiment of the hair care system, the rinse-off products (shampoo and conditioner) are formulated without encapsulated materials. The shampoo prepares and revitalizes the scalp and hair using a rice water and amino acid base, while the conditioner maintains and extends the effects of bioactives from leave-on products using non-encapsulated bioactives dissolved directly in the base material. The leave-on products (serum and mask) use the encapsulated delivery systems, with the mask specifically containing only botanical-encapsulating vesicles (second fraction of lipid vesicles) without stimulant-encapsulating vesicles (first fraction of lipid vesicles). A method of manufacturing a hair treatment composition includes preparing a base material and then cooling it to a temperature of no more than approximately 45° C. to form a cooled base material. The heat-sensitive lipid vesicles and/or other delivery systems are then added to the cooled base material, for example, under low-shear mixing conditions. This process helps to preserve the structural integrity of the delivery systems. The final hair treatment composition can be packaged in an airless container to protect the stability and bioactivity of the encapsulated materials. The hair treatment compositions can include multiple fractions of lipid vesicles for delivering different bioactive materials to the hair and scalp. The compositions can include a first fraction of lipid vesicles encapsulating a first material and a second fraction of lipid vesicles encapsulating a second material that is different from the firs
