I use this every 4 weeks to add some extra protein into my curly hair. It makes it spring right back up into my normal ringlets. It is quite a lot of steps but as long as you follow them correctly your hair will come out lovely. The smell is awful, I'm not going to lie. It's got a rotten egg scent but it doesn't linger after you wash it.

I've been using this product for years. It has absolutely saved my hair from bleach damage more then once. So worth the price you pay. It doesn't have a great scent but it goes away with a wash. I am a lifer.
