Rated 4 out of 5 by from Works Well Great product—just repurchased! It really keeps my hair looking healthy.

Rated 4 out of 5 by from Great but only if your hair is damaged I like Olaplex No.3. It really helps strengthen and smooth damaged hair, but if your hair is already healthy you probably won’t notice much of a difference. Great for repairing, not really needed for maintenance.

Rated 5 out of 5 by from Best treatment ever! I've been using this for about a year now religiously. As a girl with thick, long curly hair I needed this to revive my curls after extensive bleaching. All I can say is that it works, trust the process and every penny spend on it is worth it!

Rated 5 out of 5 by from Singlehandedly changed my damaged hair for good I've used this twice so far and..... wow. I used this after I had unfortunately been heat damaging my hair, whilst also dealing with intense British summer humidity! My hair was bleached and dyed, so it had gone through the trenches. When I laid this on and eventually washed out, my hair FELT and LOOKED different. Over time, I noticed the structure and colour was healthier. This, along with scalp scrubs, rosemary tonic, hair masks and hair oil really helped me gain back healthy hair. Little magic bottle. A little pricey for its size but ...for a reason right?

Rated 4 out of 5 by from Works ok My hair after dying. It’s damaged and dry. I’m waiting for results after 1 month using. For now, after few trying it’s ok but not that much. But again, my hair is just after dying.

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!
