Finally Got The Courage To Try It!
My hair is naturally wavy / curly especially underneath, however it grows in straight on the top. I have a definite "S" pattern but it is not tight curly. I have very coarse, thick. naturally light brown hair that I highlight blond. I was concerned that I would possibly damage the highlighted part of my hair, even though I purchased the "tinted" version,therefore, I decided to just use the product on the back underneath the top layer to the roots.
I had a friend help me since I was trying to only get the underneath section. It only took 20 minutes start to finish. Results were "ok" - some of the curl was definitely looser, however, I was hoping for more of a straight result, especially at roots where it is most kinky (btw, they said for naturally curly hair to start 1 inch from root or something like that, but we went as close to the root as possible). I think I should've left the product on longer, however, I was borderline maximum time as it was. My hair just must be very resilient. I did not notice ANY damage at all, just a somewhat looser curl that made my hair appear slightly longer. So all in all,I am glad I used this product and had better success than other "brazilian" or "keratin" treatments I have used at home before, plus much easier as I did not have to "straighten" hair with the product in it or wait 48 hours after wards to get wet or use ponytails.
I would say that this was a positive experience, with no damage, and much less expensive than other products I have tried, and with better results. And takes much less time because you are not blowing the hair dry or straightening it, I gave it 4 stars since it did not actually "remove the curl" , just made it less curly.
