First of all we are all born with a certain number of follicles. Some of us more than others. nothing is going togive you more strands than you have follicles. Now if you had hair loss that is different. You should go to a physician and get the cause diagnosed. I am dealing with my last bit of recovery from what was extensive hair loss. I did a year of medical treatments with no results then went to Oils which were the only thing that helped me. Even with the loss I have left I still have a lot of hair because it's so dense. I recently tried using a temporary spray color to cover a bald patch. I would be willing to bet it can give the illusion of thicker hair too. Washes out easily btw.
