This is probably my biggest fears also! I havie extremely long fine blonde hair and I am terrified it will fall out enough to make me bald. If I had thick hair I don't think I'd be nearly as concerned, but I don't so I am. I am taking biotin twice daily and all of my multivitamins. I am not taking Zink so I should add that. My surgery will most likey be next week. I am prepared to pay big money for extensions if I have to although they may make my hair fall out worse. lol. Really hoping for the least amount of hair loss possible. So frustrating to take such a big step that comes with such a big reward and a big consequence. :/
