Help! I am going bald!

I noticed about 6 months out from my hysterectomy that I was losing more hair, and that was back in June (2 months before my RNY) and I bought the cheap Suave Anti-Breakage Shampoo and Conditioner.  I notice quite a bit of difference.  I have pretty thin hair, luckily, it's curly, so it looks more voluminous, but my hair was still coming out pretty good.  The Anti-Breakage stuff for me seems to help with the hair that I do have on my head that tends to break. I dye my hair pretty often, but stopped right before surgery because I didn't want to process it once I had my surgery because I was afraid of the hair loss.

I also take 5000mcg Biotin in the Lozenge form that I've picked up at the vitamin store. It has 5000mcg in one pill.
