Olaplex N°.4P Blonde Enhancer Purple Shampoo | Toning Hair, 250 mL

I like the product and it works well to cut down the brassiness on blond highlights. However, be careful. I used it recently because I did not like the color my hair was toned. I used the shampoo twice too close together (my bad) and my hair turned purple, especially the older highlights 🙃Good news is it doesnt look bad, just not what I intended.

The absolute best purple shampoo you can buy. Leaves hair clean no residue. Keeps highlights amazing. Use once a week or every 2 weeks.

This Olaplex Purple shampoo is THE BEST PURPLE SHAMPOO AND CONDITIONER! PERIOD. I have had highlights for 4 years and have tried every purple shampoo and conditioner! And, nothing like the results I was looking for, till Olaplex. Beautiful color not drying at all.its expensive but you just need a little. Worth every penny.

Thought a purple shampoo was a purple shampoo...and didn't see a big difference...but my hair stylist recommended this one. It was an investment, but it was super worth it! One wash and noticed an immediate difference! Highly recommend

This is a pricey shampoo and Amazon should do a better job of packaging and protecting this product. This arrived to me today with a broken cap and no protective wrap.This shampoo is amazing and the best purple shampoo on the market. A little bit goes a long way so don’t be discouraged by the small 8.5oz size.

This works quickly to neutralize brassy, yellow tones — a few minutes and hair looks noticeably cooler and brighter without turning ashy or purple-tinted if you don’t overdo the timing. Lathers well, purple pigment rinses out clean without staining hands, nails, or the shower. Hair feels conditioned afterward, not dried out or stripped like some purple shampoos leave it. A little goes a long way, so it’s lasted longer than expected even with weekly use. Great for maintaining color-treated or highlighted hair between salon visits, keeps blonde looking fresh instead of dull or brassy

This is absolutely the best purple shampoo you can buy ! It leaves your hair nice and toned as well . No brassiness if you use this shampoo, using it with the conditioner leaves your hair soft , less damaged due to the bonding process it has as well . You will look salon fresh and feel great as well .

Wow. Just wow. This totally refreshed my blonde balayage which had turned more copper after months of summer sun and very chlorinated water. I used as directed and also followed with the conditioner recommended. It turned out even better than when I came home from the salon! I’m completely shocked. Totally valuable purchase and will continue to use in between salon visits!

Amazing

É bem pigmentado e depois do uso eu sinto meu cabelo um pouco seco.

Works well keeps my hair blonde and smells great too

I alternate it with my clarifying wash to keep the tone clean without over‑drying. The price was good compared to the usual RRP
