Hair has psychological and sociological importance throughout the ages in framing the personality and general appearance of an individual. Significant progress is being made on discovering an effective and safe drug for hair growth. Angiogenesis, androgen antagonism, vasodilation, potassium channel opening and 5-alpha reductase inhibition are the major non-surgical therapeutic strategies of hair growth promotion. In spite of a flood of drugs claiming to be useful as hair growth promoters, more rational strategies, which can target the problem areas or stages of the hair growth cycle effectively, are still awaited. This article highlights the developments in hair rejuvenation strategies and reviews the potential of herbal drugs as safer and effective alternatives.
