Abstract

Objective Nanotechnology has been intensively applied to the development of novel cosmetic products for hair and scalp care during the last decades. Such a trend is corroborated by the fact that about 19% of the total nanocosmetics registered in the StatNano database are intended for hair and scalp care. Nanotechnology-enabled formulations based on nanoparticles, cyclodextrins, liposomes and nanoemulsions have emerged as novel approaches due to chemical stability and their controlled release. Regarding hair care formulations, nanocarriers can target the hair shaft, hair follicle and scalp. Therefore, they have been used to treat several hair disorders, including dandruff and other hair-damaging conditions. Methods This review addressed the most important nanocarriers applied to hair-related disorders improvement. Furthermore, the application for hair photoprotection and improvement of hair colour duration by nanotechnological formulations is also approached. Besides, we provided an overview of the current scenario of available nano-based commercial hair products and novel patented inventions. Results From the patent search, the Patent Cooperation Treaty was pointed as the most important depositing agency while the United States of America has been the most depositing country. On the contrary, according to the StatNano database, Brazil stands out in the hair care worldwide market, and it is also the main producer of hair cosmetics based on nanotechnology. Conclusion As nano-based products offer several advantages over conventional cosmetics, it is expected that in future, there will be more research on nanocarriers applied to hair disorders, as well as commercial products and patent applications.

Liposomes for Cosmetics

Liposomes have emerged as a revolutionary component in hair care products, offering targeted treatment for hair shaft and scalp disorders. These microscopic, spherical vesicles can encapsulate active ingredients, enhancing their delivery and efficacy. In hair care, liposomes penetrate the hair shaft and scalp more effectively than traditional formulations, ensuring that therapeutic agents reach the intended site of action. For hair shaft disorders, liposomal formulations can deliver nutrients and repair agents directly to damaged areas, improving hair strength, texture, and shine. Ingredients like vitamins, keratin, and essential oils, when encapsulated in liposomes, can repair and nourish the hair from within. In treating scalp disorders, such as dandruff, psoriasis, and seborrheic dermatitis, liposomes ensure that active ingredients like antifungals, anti-inflammatories, and moisturizers are efficiently absorbed. This targeted delivery minimizes irritation and maximizes the therapeutic benefits, leading to a healthier scalp environment and promoting overall hair health.
