Customer reviews
The finished result is actually lighter than it looks in the picture. My walls are BRIGHT yellow, so it looks more yellow. And I didn't tone it right after. That is a picture right after I finished 3 applications with Olaplex. It might have been a little drier, but my hair felt fine afterward. It didn't do ANYTHING to the natural color of my regrowth. That's one of the main reasons I chose this product. I did this do I could grow my silver white hair out.

I put a red tint in my hair, and I hated it. I tried a lot of other ways to get the red out, but nothing worked. I finally tried COS and it took the red right out. I recommend it.
