Hello, Thank you for posting on HCM. Greying of hair occurs when the melanin of a particular hair follicle is permanently exhausted.Premature greying of hair is attributed to many factors like diet,nutrition, UV rays, pollution, cosmetics/dyes/colors, genetics, medications etc. Treatment of grey hair is pretty challenging. I would advise you biotin and calcium pantothenate combination tablets for atleast 6-8 months, which will also help in your hairfall issue. Apply Altris gel containing Melitane, which is a new compound shown good results in premature greying of hair. Also, a novel hair sunscreen cum hair serum Q sera black has shown good results in preventation of hair damage from sun and pollution. For your Dandruff,i would recommend you a short course of oral antifungal drugs like ketoconazole/itraconazole and a lotion containing sertaconazole and betamethasone twice a day over scalp for few weeks. Use a medicated shampoo containing ketoconazole and salicyclic acid twice a week. Take antihistaminics as required for itching. Avoid excessive use of hair oil. Take plenty of fresh fruits and vegetables in your diet and try to de-stress your lifestyle. Try to limit your smoking and alchohol intake. Hope this will take care of your query. Thank you Dr Hardik Pitroda
