I’m sitting here making a really sad face right now. I was invited by BzzAgent to do a review on the Smooth ‘N Shine Keratin Power Semi – Permanent Hair Tamer, and guess what? I CAN”T USE IT!! It says that its safe to use on natural hair , but it indeed is not. The Neutralizing Milk contains Sodium Hydroxide, which is a straightening agent used in relaxers. Honestly, that is not the only harsh ingredient in this product. So for any natural person out there that wants to try this, don’t. You will be messing up your hair journey. Sorry BzzAgent, can’t do this one.
