I have a thyroid condition that negatively impacts my hair and I’ve tried everything to get it to grow and thicken. I tried just about everything over-the-counter, vitamins, and even prescription stuff. I quit the prescription hair growth options because of side effects. After about six weeks of using Folitin, my hairdresser noticed a positive change in my hair and I actually started to cry. I can’t believe I finally found something that really works!
