I have been losing excessive hair these days, and what bothers me is the fact that I just use hair dryer for my hair, and nothing more than that. I am just in mess, and I am on a look out of some effective ways to elevate hair regrowth now! I am just 19 and I am quite perturbed because of this hair loss, at this age. I have started vitamin supplements, and apply castor oil every night on my scalp. As far as shampoo is concerned, I bought LâOreal shampoo for myself, but even this doesnât seem to help! After a review on biotin, I could assume that it helps in elevating the hair growth process. I would really like to know from some hair expert now, if I could use biotin at my age for hair regrowth. Please advice! Thanks.
