The product goes through your hair effortlessly & really makes a difference with the shine & overall health. My split ends look much less noticeable. It's super easy to use & i would recommend this to anyone.
Leaves hair feeling like silk!
I apply this to my damp hair after my shower, blow dry, and have the softest hair ever, esp the next day. It's soft and makes my curly hair products work even better somehow. My hair also feels stronger after every other day use.

I have been using the Redken Acidic Bonding Day and Night serum after styling my hair and it has really been helping to keep it strong and shiny. I feel like it helps avoid damage from using hot tools on my hair and my hair is looking really healthy. The scent is a little more on the masculine side in my opinion but I'm not upset about it at all, I think it smells really good.
