Nanotechnology-Based Cosmetics for Hair Care

Eight years ago, the review "Nanotechnology-Based Cosmetics for Hair Care" explored the potential of nanotechnology in hair care products. The unique properties of nanoparticles allowed them to target the hair follicle and shaft, improving hair appearance. Nanomaterials were found in almost all personal hair care products, enhancing the stability of ingredients, aesthetic appearance of products, and targeting active ingredients to the hair. They improved hair moisture, gloss, and lubrication in shampoos, repaired damaged cuticles and restored gloss and texture in conditioners, and reduced toxicity in hair dyes. Nanotechnology was also used to encapsulate minoxidil and finasteride, the only two FDA-approved treatments for hair loss, to enhance delivery and minimize side effects. Nanoparticles were also used as efficient carriers for drug delivery into hair follicles, potentially beneficial for treating conditions like alopecia. The review concluded that while nanotechnology showed promise in hair care, further research and a better understanding of toxicity were needed.
