I am 21 years student and i am always busy in my studies. i am a little fat too my hair colour is black . i have some white hair growing from my 15 years age. now i have 1% or more white hair . what should i do for it sir?

Once the hair follicle lose the pigment color then the hair becomes white. There is no way-that pigment can be returned to the follicle. There are two things you can do1. little color the roots second increase the number of black hair so white and hidden.2. Increase the number of black hair you can use castor oil and see if it works , take biotin Please don’t stress about it .Hope it helps.
