At first I was using it wrong because I didn’t fully read instructions. I was washing it out after 4 minutes. Now I’m leaving it on as instructed and brushing after the 4 minutes and styling as usual. I feel like it is making a difference. My hair is dry and damaged from bleach.

I can’t say enough positive things about this product. Pair it with the hair oil and it will knock your hair out of the ballpark. Super soft and shiny. You don’t need very much although it might feel like you do. Make sure to follow the directions to get the most benefit.
