Just tried it yesterday, I had tha sample size pf 60ml..
Waaaay to small quantity for my hair, so I had to apply it just in the 3/4 of my hair and not from the roots.
I compare it with the original f.hyde QOD max
Very dissapointed from the result. Those red highlights appeared again, it did nothing for the hair color. I dyed my hair (blue black) about 6 days ago and it just ruined it. It did nothing when it comes to straightening, it s just that my ends are a little bit softer.
I mostly tried it to see how it would react with my haircolor and I give it a 0 grade on that.
