I have been taking this for about five months now. I really have a lot of thickening of the hair where I am not balding. Sadly, those patches aren't that different. I probably have a deeper hair follicle problem that I am working on with a dermatologist. But the areas that were just thinning due to age and likely stress are much, much thicker, and my hairline which I did not think I had a problem with is filling in. Great product!
