Hello. Thanks for writing to us at healthcaremagic The onset of grey hair and the speed at which people go grey varies from person to person. Premature graying is defined as first onset of grey hair before late teens for Caucasians and before age 30 in Africans and Asians. The color of hair mainly relies on the presence or absence of melanin pigment. It has been shown that grey hair have greatly reduced active melanocytes in the hair follicle. Premature graying of hair occurs more commonly without any underlying pathology and is said to be mostly inherited. A role is postulated for environmental factors such as ultraviolet light, smoking, deficiency of trace elements and nutritional deficiencies in the causation of premature graying. Studies have also shown a relation between premature graying of hair and low S. Ferritin, S. Calcium and vit D3 levels. Currently available treatment options for premature graying are limited but are worth the indication: Para aminobenzoic acid (PABA) and Calcium pantothenate are well known treatments and are known to arrest and even reverse premature graying. Topical 1% Melitane is a new molecule that has recently become available for premature graying of hair. It is indicated to stop and reverse premature graying of hair. It is available as a gel and needs to be applied once daily (2ml) at night at the roots. Once response is achieved, maintenance applications will be required. Treatment is long term and it is important to have a fair trial of 3-6 months before deciding on future course of action, whether they are going to be effective or not. These are all prescription medicines, I would suggest that you talk to your dermatologist for the needful Regards
