Suggest Remedy To Grow Hairs From The Follicles Where Hair Loss Has Taken Place

I'm a male of 18 yrs. This winter, i had much dandruff because of which hairs started falling. I didnt cared first but after some weeks, i noticed that my scalp is becoming bald. Then i used selenium sulphide shampoo, and dandruff started disappearing. Now my scalp is totally dandruff free but there are less hair left in my scalp. I want to know how to grow hair from those follicles from which hairs are lost.
