Advance approaches in alopecia

Abstract

Alopecia is characterized by hair loss mainly on scalp some time on other resign of the body that has negative psychological and social impact on patients. Androgenetic alopecia and alopecia areata are common disorders. Androgenetic alopecia is the sensitivity of scalp follicles to dihydrotestosterone and alopecia areata is an autoimmune disorder. Current studies have explained the efficacy of corticosteroid therapy or the combination of ultraviolet A therapy and systemic corticosteroids for severe AA. Finasteride opens up new possibilities for the treatment of androgenetic alopecia. Current drug treatment approaches use regrowth stimulators such as minoxidil and finasteride for androgenetic alopecia, as well as corticosteroids, PUVA therapy for alopecia areata. Targeted delivery to the Hair follicle units helps faster targeting to cells that accelerate drug action by faster availability of drug, novel combination treatments combinations like tretinoin with minoxidil shows better results, gene therapy are new approaches that are under developing stage and giving satisfactory results on animal as well as humans.
