Please help! I have been having these small patches of hair loss for about 6 years now. In the begging, it was never this bad. Each year, it progressively has gotten worse. I have seen many dermatologists and they don't know what the cause is. I wish I knew what I am dealing with. If anyone has experienced this before or know anyone that has, please offer me some advice. I have beautiful hair but I constantly have to wear weave and wig to hide the spots. In the process, I have lost faith in my natural hair. I am only 20 years old and hair loss is not something that is common in my age.
