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 and results are not very encouraging. I would advise you biotin and calcium pantothenate combination tablets for atleast 6-8 months. Apply Altris gel containing Melitane, which is a new compound that has shown good results in premature greying of hair. Also, a novel hair sunscreen cum hair serum Q sera black has shown good results in prevention of hair damage from sun and pollution. Use gentle shampoo and conditioner for regular hair wash. Use coconut oil twice a week for scalp nourishment. Drink plenty of water and take plenty of fresh fruits and vegetables in your diet Try to de-stress your lifestyle and indulge into regular exercise. Try to limit your smoking and alchohol intake. I am sure this will take care of your issue. Thank you Dr Hardik Pitroda
