Loved this hair mask, left my hair feeling healthier and nourished 

great hair product! I am delighted! I recommend to try

Turned my highlights green .. overall not a bad product .. but not for me 

After doing a tonne of research on how to get the red tones out of my hair I decided to try this one. So here's the thing, I have brunette hair with balayage. This absolutely did make the browns ashy and took the redness out HOWEVER the blonde ends of my hair especially around the front went bluey green. The packs are small so I bought two, and needed both to cover all my hair.  If you have short, brown hair this could be great. But don't bother if you have any highlights at all. 

Bought this in the hopes of toning my faded out balyage and you can’t tell a single difference on a single hair despite following instructions. Dissatisfied
