I am also experiencing a major amount of hair loss. I am 31, healthy and over the past year have lost 65 lbs. I started taking Alli when it first came out in June. I do not over use the product, I mainly use Alli when I eat out. I am not too restrictive on my diet. And get PLENTY of protein. I take a multivitamin daily, along with a Biotin supplement for hair support. I noticed about 3 months ago my hair falling out more then usual. For the past month, it's unreal how much hair I am losing. I can pull my fingers though my hair and the hair just falls out. I already saw my doctor for blood work. Everything was normal. I am really wondering if Alli has anything to do with it. I called the comsumer line mentioned above, they documented my case, but offered no further info.
If there are any more people out the experiencing hair loss, please, either reply to this message or call the comsumer line so that we can know for sure if this is a side effect.
