ABSTRACT :- Hair is an important indicator of health and can have a major effect on an individual’s cosmetic appearance. Research within the cosmetics industry has let out that when nano materials are put together into hair care, they can enhance the benefits of active ingredients in order to improve hair cosmetics. Within the cosmetics arena, the unique size and intrinsic properties of nano particles can be tailored to target the hair follicle and shaft. Aims to provide an overview of cosmetic nano carriers that can be employed to increases the appearance of hair. Popular drug therapy allows for the delivery of substantial amounts of drug to the site of disease, though poor and erratic drug absorption and active ingredient stability often confound delivery. Recent progress in nanotechnology allows for the development of carriers with enhanced ability to penetrate and permeate the skin. While cosmetic products are not intended for systemic absorption, their efficacy depends on entry through this armor.
