Take multivitamins first. Before trying any other supplements. Just take that for about 1-2 months. Enough from your body to catch up from major operation. And after that, if your worried about your hair and skin, there's a supplement specifically made for Hair, Skin and Nails. I just forgot the name of the supplement, but I'm sure it's from Maxalife Company. It's a supplement product that can bring the health back to your body, allowing you to radiate with a glow of healthy skin, hair and nails. hope this tip helps you!
