Rated 5 out of 5 by from Will repurchase I use this with no. 0 every 4-6 weeks and before having bleach highlights. Makes a difference. And, who doesn’t want some ‘me time’ whilst it dies it’s thing!

Rated 5 out of 5 by from Tiny bottle but works only get it on sale I leave it on for 40 mins for maximium results but you can see a difference after the first use, the bottle is tiny and I have very long hair so luckily not a everyday use product, worth a splurge for damaged hair

Rated 4 out of 5 by from Smoothing but expensive I will say I did see some smoothing, and my hair did feel nicer to touch, but it's incredibly expensive for how little it does. I simply don't believe people when they say it restored their burnt hair, etc.

Can it be used on blonde hair?

Asked by: Anonymous
Absolutely! This is for all hair types including virgin, coloured, textured or highly compromised. It really did save my bleach-damaged blonde hair.

Can the hair perfector be used for all types of hair? My hair isn’t bleached but looks dull and has been falling out a lot. Does this help with that and if so what effect does it have?  Thank you!
