Abstract

According to W.H.O in India, its incidence is high in the age group of 20-30 years. In Ayurveda premature greying of hair is called as Akala palitya (premature gray hair).

The use of purification procedures of panchakarma (detoxifying therapy) has prime importance in the remedies mentioned for premature greying.

Summary
Hair care is a part of trichology concerned with the nourishment, maintenance and prevention of diseases related to hair and scalp. The human hair follicles contain two types of melanins, the black-brown pigment eumelanins mainly present in black and brown hair and the yellow or red pheomelanins in blonde hair and auburn [3] Both epidermal and follicular melanocytes are derived from immature melanoblasts that migrate from the neural crest into the skin during embryogenesis. Premature greying or Canities may reflect a genetically regulated early exhaustion of the melanocyte reservoir's seeding potential or some defect in cell activation/migration compounded by environmental factors, inflammation, or psychological stress [5].
