Premature greying at 25 is common in India and is largely genetic - if your father or mother greyed early, the pattern usually follows. Hair that has already turned white will not go back to black, so please be careful with products or clinics promising reversal. What we can do is slow down further greying and correct any deficiency behind it. Please get
vitamin B12,
vitamin D, serum
ferritin, CBC and
thyroid (
TSH) checked, as low B12, low ferritin and thyroid problems are the correctable causes we find most often. Eat well - eggs, milk, curd, dal, green vegetables, nuts and seeds - stop smoking if you smoke, cut down stress and sleep properly. Do not use harsh chemical dyes frequently; if you want colour, natural henna or a low ammonia dye is gentler, and a dermatologist can advise on the right one. Supplements only after reports, not blindly. If greying is spreading very fast or you also have hair loss or patches, please get a dermatologist opinion. You can consult me on Practo or at Synergy Multispeciality Hospital, Miraj to review your reports.
