It Works
I was pretty skeptical going in on this. I bleached my naturally level 2 hair and had the usual damage from a double-process bleach, nothing spectacular, but I wanted to get my hair back to feeling healthy. I've tried a lot of products that haven't done what they promise when it comes to chemical damage, but after using k18 two times, my hair looks and feels as good as it did before I bleached it.

Transformative!!
This is by far the best hair product I have ever used. I have natural white/grey hair and it makes my hair texture silky and smooth. Also, my kids swim a lot. Occasionally, I will use this hair mask on them and it completely erases damage from pool chemicals. The larger size is awesome because I donāt have to deal with the anxiety of running out of my favorite product as fast!
