Hair has so many reasons like malnutrition, poor hygiene, low hb, stress or any other associated illness like
thyroid. If U have Waight issue then do lab test for thyroid-
tsh. First do this then we can give some advice. U can consult me on practo direct.
If U have no other illness then biotin supplement like Tab Follihair 1 daily and Tab tonofolic Z 1 tab twice in a day give result.
