Oh em gee! This has been a godsend! I have grey frizzy, coarse hair. I have tried everything free shampoos and conditioners, hair dryers, flat irons and nothing would help me tame the frizz. I saw a content creator use this, and decided to give it a try. From the first try, without me really knowing how to correctly use it, I noticed a difference. My hair is smooth, bouncy and manageable, and I love it! Even the shine is back. I would highly recommend.
