Olaplex Nº.4P Blonde Enhancer Toning Shampoo, 8.5 oz.

[This review was collected as part of a promotion.] I've tried several purple shampoos over the years, and this one is by far one of my favorites. It does an excellent job of neutralizing yellow and brassy tones without leaving my hair looking dull or over-toned. My blonde highlights look brighter and fresher after just one use. What impressed me most is that it cleanses well without drying out my hair, which has been a problem with other purple shampoos I've used. My hair feels soft, smooth, and healthy, and the color stays vibrant between salon visits. A little goes a long way, so the bottle lasts quite a while. I highly recommend this shampoo to anyone with blonde, gray, or highlighted hair who wants to maintain a cool, salon-fresh color while keeping their hair feeling healthy.

Lathers more than other purple shampoos I’ve used and seems to work nicely on grays but it will stain your towels if you’re not careful. Tried it for the first time tonight and am bleaching a Crown Affair towel as I type this!

This stuff works. It’s pricey but worth it.

I was very disappointed. It turned my highlights purple! It’s not good for very light highlights. I’m going to return it. I love Olaplex and use all their products, but not this one.

From the first use, I received compliments about the color and shine of my hair. Absolutely very pleased with this shampoo.

Really great. After the second use it was like bow chicka— New staple product
