very effective!

5 stars out of a maximum of 5

it doesn't decrease hair quality which is difficult to find in purple shampoos, but don't leave on for too long as it will dye purple lol, I find 2 minutes to be more than enough

Uusually love Olaplex shampoo - but......

2 stars out of a maximum of 5

Not a fan of this - didn't seem to do anything over and above what a cheaper 'purple' shampoo does - so not sure that it's worth the extra money

Good purple shampoo

5 stars out of a maximum of 5

I try so many purple shampoo but this one it’s my number one. My hair doesn’t look dry anymore. I like Olaplex products, I combine this shampoo with number 3 and 5 that’s perfect!

Great product.

4 stars out of a maximum of 5

After going blonde balayage, my hairdresser recommended this product to me to up keep my blonde! I use it once a week and keep it on for 5 minutes. It seems to be working well, no yellow in my hair and people I know ask me constantly if I’ve gone blonder! 10/10 would recommend

Nice on the hair

4 stars out of a maximum of 5

Not as drying as other purple shampoos but doesn’t leave my hair feeling as soft as the standard olaplex shampoo. The colouring is nice and definitely keeps brassy tones at bay
