Hello and Welcome to healthcaremagic. You have 2 concerns: -Premature graying -Hair color induced hair loss 1) Premature graying is defined as gray 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 graying 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 graying. 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 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. 2)Ammonia containing hair colors do cause increased hair shedding in some individuals. You could try an organic hair color, e.g Bio- Vegetal hair color, which is ammonia free and therefore expected to be free from this side effect. Hope this helps you in getting a solution to your problem regards take care
