Nanomaterials in hair care and treatment

    February 2022 in “Acta Biomaterialia
    TLDR Nanomaterials can improve hair care products and treatments, including hair loss and alopecia, by enhancing stability and safety, and allowing controlled release of compounds, but their safety in cosmetics needs more understanding.
    The review article "Nanomaterials in hair care and treatment" discusses the potential of nanomaterials in improving hair care products and treatments, including those for hair loss and alopecia. Nanomaterials can enhance the stability, safety, and biocompatibility of active compounds in hair care products, and enable controlled release of these compounds in hair and scalp. The document highlights the use of organic and inorganic nanomaterials, such as polymer-based and lipid-based nanoparticles, nanosheets, nanotubes, and inorganic nanoparticles. It also discusses the use of nanomaterials in delivering antifungal and anti-lice treatments topically, reducing side effects associated with systemic administration. The document mentions the development of nanostructured lipid carriers and vitamin E-loaded carriers that showed protective effects against hair damage and discoloration. It also discusses the use of nanomaterials in delivering anti-hair loss drugs like minoxidil and finasteride, improving their efficacy and reducing topical adverse effects. However, the document also highlights the challenges and safety concerns related to the use of nanomaterials in cosmetic formulations, and the need for more studies to understand their safety.
