Some people do lose hair but i read here that biotin and zinc help. Trust me it does work, my hair is growing like crazy. Also, you must eat 60-80 grams of protein a day and that helps with reducing hair loss. You lose 1-2 lbs a week and after 3 years the amount of weight loss is equal between the 2 surgeries. Ypu are suppose to have 2 chewable vitamins a day. I take flintstones. Yuk! Lapband surgery was the best decision i have ever made. Surgery was sept 4,08 and i am down 44lbs. Good luck hope this helped
