My 2 1/2 year old son had his hair pulled out by a toy. He has now turned 3 and his hair has not grown back. The scalp appears to have extremely fine hair that is growing and a maybe five strains of normal hair. Does this mean his follicles are damaged and the hair will never return?
I do not know. Your son may have had a traumatic traction hair loss and it may never return, but you really cannot tell if the hairs will grow back until one full year has passed. Give it a bit more time to regrow.
