Best Purple Shampoo

4 stars out of a maximum of 5

This is the best purple shampoo I’ve tried. However be careful as it’s very potent and can easily stain your hands! Doesn’t make my hair feel too dry either which is a bonus.

Purple shampoo

4 stars out of a maximum of 5

Most potent purple shampoo I’ve used. If your blonde needs nuteralising this will do it too potent to be used every day. Wash of quickly or will dye hands

My blonde hair is in heaven

5 stars out of a maximum of 5

I’ve honesty tried quite a few different purple shampoo’s…. All of which would be considered premium brands I guess… I’ve enjoyed most and thought they do a fairly good job but WOW, the olaplex is truly something else!! The condition of my seriously bleached hair is AMAZING- (my hairdresser is in awe) but this gives my hair the tones I actually want!!! Goodbye yellow & brassy, Hello cool blonde, I need to stock up on this product to ensure I have a lifetime supply x

Review for Olaplex No.4P Toning Shampoo

4 stars out of a maximum of 5

This product is an effective toning shampoo that I use to maintain my newly bleached blonde hair, as it really does help neutralise any brassy tones between hairdressing appointments. However, it has proven to be quite drying to my hair, so I can't use it as often as I'd like. Hence, the four star rating, not five.

Not for me

2 stars out of a maximum of 5

Not a fan it’s overhyped and left my scalp itchy to the point it bled.  Give it 2 stars as it didn’t dry my hair out as much as some of the other purple shampoos I’ve used.

This product is great for blondes, keep the yellow brassy tones away. Would highly recommend for blondes.

Brilliant

5 stars out of a maximum of 5

I used to use Fanola but it was so drying!  I absolutely love this shampoo from Olaplex and this is a repurchase for me.  I think it’s the best purple shampoo I’ve ever tried. Even better than the davines one.  I’d just like them to add a purple conditioner or mask now
