Hello and Welcome to healthcaremagic. Premature greying is defined as grey hair onset before late teens for Caucasians and before age 30 in Africans and Asians. Currently available medicines target this group of people, rather than natural greying due to ageing. A role is postulated for environmental factors such as ultraviolet light, smoking, deficiency of trace elements and nutritional deficiencies in the causation of premature greying. Currently treatment options are limited but they are worth the indication, before you develop considerable amount grey hairs: Para aminobenzoic acid (PABA) and Calcium pantothenate are well known and are known to arrest and even reverse premature greying. PABATAB-BZ tablet marketed by shalak s pharmaceuticals in India contains both of these ingredients in adequate concentration (para-aminobenzoic acid 100 mg, biotin 5 mg, zinc 25 mg, calcium pantothenate 100 mg). Recommendation is to take thrice daily for 6 months. Topical 1% Melitane is a new molecule that has recently become available for premature greying of hair. It is available as a gel and needs to be applied once daily (2ml) at night to the hair roots, both beard and scalp, similarly. Hope this helps you in getting a solution to your problem regards take care
