I don't normally write reviews, but decided this was worth sharing if it helps others. I have been using the shampoo for a couple months now, and I am a believer. A little background on my hair..My hair has been falling out and thinning for years. Plus a few years ago I had bariatric surgery, which means more thinning and hair loss .. My hair is so thin if I twist or braid a pony tail it's no thicker than my pinkie finger. Since I've been using this product, I do have new hair growth and it's beginning to thicken up!!! The main reason I wanted to write this, is far a long time if my hair happened to get pulled/snagged or caught on something. I wouldn't feel it coming out, now if it gets caught on something, where it's being pulled out, it actually hurts. I recommend buying one bar to see for yourself, you'll come back for more..
