love, love, love this product. I have had frizzy hair for a few years now. I just turned 40, so it may be an age thing (I've noticed that my hair is becoming a little coarser). I've always had dry hair (and skin) and my hair is very fine to begin with, so it breaks easily. I also get my hair highlighted every few months, which can't be good for my hair either. I tend to get split ends rather quickly-- so much so that the bottom of my hair tends to sort of fan out a little instead of hanging straight. I've tried every product I could find that promised frizz removal: shampoos & conditioners, leave-in treatments, natural oils, anti-frizz serums, etc. Nothing worked. It was especially embarrassing because the hairs that would break near the top of my head would also frizz up, making my hair condition even more noticable. I was skeptical about ProMend, but decided to give it a shot. Let me tell you, this product does what it says it will. From the first application, I noticed a significant difference. But the real difference was that this effect lasted! The directions say to apply about once a week, but it can be used more often if needed. I first used it about 3 days ago and can't find a single split end! The directions say it will work from the first application-- and it does. It's brought down the frizz on the top of my head as well. I am so happy, so relieved to have finally found something that actually works for me. My hair looks so much healthier and just better in general. Very glad I don't have to be so self-conscious about my frizz anymore.
