I feel like it’s a little too soon for me to tell you what I feel about it. I know it works. I used to have extreme areas that would fuzz up and I could never get them straight now that I’m older, 76, my hair is flatter and straighter. I still have frizz in the back area, which makes me feel good to take care of that problem. I do wish I had this product when I was a hairdresser for 58 years, because I had a couple of customers that were so bad and I worked so hard, and they could’ve used it!
