I have loved this product from day 1 of using it. Only thing is you have to use it correctly or else it will leave your hair out of sorts. And only for 5 minutes, and for best results follow it with the Hydrating masque. It leaves my hair feeling soft, manageable and nourished. I only use this protein reconstructor once in every 2 weeks to make sure it does not damage my hair more than it does good.
