Hello and Welcome to healthcaremagic. Premature greying is defined as 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. 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 be come available for premature graying of hair. It is available as a gel and needs to be applied once daily (2ml) at night to the hair roots (scalp as well as beard). Hope this helps regards
