I had my RNY on 2/27/12 and my hair started thinning out after about 5 weeks. My nutritionist recommended an OTC supplement called Hair, Skin and Nails. She said there are no guarantees but it worked for me. You can but it at Costco, Sams Club and WalMart. It's very cheap!!!
Thank you so much Pat, I will go to Walmart today and get the Hair, Skin and Nails product, do you know which brand I should get, because Ive seen a couple different ones.
