Please please understand that hairloss is a possible side effect. I read about it and didn't think it would happen to me. About 12-15 days into taking large doses of B5, even with a B complex, I began losing hair at an alarming rate. It took me many months and hundreds of dollars trying all sorts of things to gain control over the situation. What ended up helping me was balancing my hormones-- DIM, Iodine and folate. I took a host of other supplements as well but believe these 3 helped the most and truly balanced my hormones---blood tests before and after proved it.
