This is a BIG fear of mine as well...My hair is at least 20 inches long & it is light red with blonde... I just had my surgery on 8-8-12... i knew this was a side effect of extreme weight loss, some people get it worse than others...i too have had ALL if any confidence in my hair...even strangers come up to me about my hair,,,it has been the ONLY thing that has made me feel sexy over the years!!! I don't want to lose too much, i already lose enough normally...please my precious hair, please don't fall out!!!!
