This, the shampoo, the antisnap treatment, it's all brilliant made a world of difference to my bleach damaged hair.

Seems ok, prolonged use will only tell its effectiveness 

This stuff is better than olaplex! I have dry and damaged fine hair and feel like I have tried every mask under the sun to help it. I’ve had the full olaplex system from 1 through to 7 and nothing has made my hair feel as good as this did. It’s so much stronger and silkier but so weightless. I have less knots and it’s reduced my breakage noticeably. I would definitely buy again and would highly recommend. 

My hair had been damaged by my over colouring it during lockdown and this has helped to make it feel less dry and appears to have stopped it breaking off. I used every other day, initially and now once a week as overuse can cause it to feel sticky. Worked really well for me.

I am Blond Bleached blond !! So I am in love with this amazing smoothie for the hair!! once per week also!! Super super
