Great product! I have very fine frizzy afro/métis hair but the product seems to have the same effect as a classic Brazilian straightener, without the inconvenience of application and the toxicity of the product. Best of all, I was able to apply it on my own, whereas I usually need someone else to pass the brush round the back. It was so easy to prepare and apply, and the results lived up to my expectations. I'll definitely be buying again!
