Around my 4 month mark my hair starting falling out...alot! I started using the Nioxin shampoo and conditioner and it helped make my hair healthier and stronger. My hair has started to grow back, I have lots of little hairs popping up now. I had this happen one other time when I had ankle surgery, the doctor said it was my body's response to the anesthesia. Everyone is different but it should be just temporary, hang in there.
