You hair loss is normal after surgery. It is caused not only by the dramatic shift in your diet, but also due to the shock on your body due to the surgery. It's called Telogen Effluvium. On a normal scalp, about 90% of your hair follicles are producing hair, and 10% are in the resting phase. This is called the anagen phase. In this phase, your hair falls out of the follicles, and then grows back in. When you've experienced a shock to your body, it sends 30 to 40% of your hair follicles in to the resting phase. This state is called telogen.
This is temporary, and I know it is scary. It happened to me after my tummy tuck, but not after my bariatric surgery. I took Vita4Life Hair, Skin & Nail after both procedures. I found my hair loss wasn't too bad when I experienced it and I'd estimate I only lost about 15% of my hair. It grew back just as healthy and I attribute the lack of loss both times to these Vitamins. I'd recommend trying them. It can't hurt. And please believe me... it'll be okay! I was scared too. It'll grow back I promise! Here's the link. http://vita4life.net/products/bariatric-vitamins-hair-skin-and-nail-support.html
