Jul 22, 2014 - After speaking with our daughter she agreed be a volunteer for naturallyycurly.com. She loves having her natural hair straightened but she is always quick to sweat it out. She has a mixture of 3b and 3c curls and her hair is very thick. When we were sent this product for review, I read over the directions and it was very simple. I comber her hair out prior to washing with step 1 (cleansing shampoo which did not leave her hair tangled but did strip her hair of build up) and then again before applying step 2 (leave in conditioner) just too make sure that I would be able to apply a thin coating like the directions stated without over saturating her hair. Once I finished, i combed her hair to make sure the leave in was evenly distributed. After waiting the 20 minutes, I proceeded to blow dry her hair. It left her hair pretty straight and after I flat ironed it, her hair was left looking amazing. What really sold me on it was that she went outside later on with her brothers and played for a while. She can in sweaty and all but her hair was still straight. It hadn't even tried to revert back. Now we live in Vegas and our summers are always in the 110's.I truly love this system and she does as well. WE both love her natural curls but it is nice to know that she can use something like this when she wants straight hair that will last more than a day or so, knowing that she can always go back to her curls. This is a great system and our daughter absolutely loves it as well. I would definitely use it again when it comes time to straighten her hair when she wants too!!
