I am 17 years old and my hair started to fall very fast I am worry now what to do I have used many shampoo but nothing happen some tips to grow hair:)?

Be seen. You need to be seen...When hair falls out fast you need to be sure it is not a thyroid issue. To help regrow hair there is a supplement called hair, skin, and nails that is helpful...Biotin is important to help regrow the hair.
