My hair has been 'shedding' at an alarming rate, in the shower, for years. I finally started noticing that yes, my hair really is not as thick as it was in my youth, and decided that it was time to do something. I tried the Nioxin, and within 3 shampoos, noticed a DRASTIC reduction in the amount of hair loss after a shampoo. It was unreal how quickly it worked. I am using the cleanser along with my regular conditioner, Nexxus Ensure. The Nioxin cleanser seems to make my hair really squeaky-clean, possibly even a tad bit dry right after rinsing it out, BUT it seems to allow my conditioner to penetrate/work even better. Can't say that my hair LOOKS thicker, but then thankfully, I've always had really thick hair, and the only one to have even noticed the thinning in my hair was me. This isn't a cheap product, but it works and I'll continue to use it. PS, I've heard that Sally Beauty Supply makes their own version, which a friend has tried, and likes. I may give it a go. It if works, fine, if not, I'll go back to my Nioxin.
