I have been losing my hair for about 6 months now. It progressed over the last 2 months and I don't know what is causing it. I am in menopause now and I have been taking natural progesterone for the last month and a half. I have had my thyroid checked and it's okay. I am using Nisim shampoo and conditoner for about 2 weeks and the loss has slowed some but it's still coming out enough that it's scarying me. Can anybody offer me some guidance? What could be causing this? I should mention I have tender spots on my scalp but I don't see anything in those area's. Any suggestions?
