OlaplexNo. 4P Blonde Enhancer Purple Toning Shampoo, Repairs, Hydrates, & Brightens All Blonde, Lightened, & Grey Hair, 8.5 fl oz

Good sign when it starts to dye your forehead and hands tentatively. I’ve used it once and left it on for a significant amount of time because I had extreme yellow/brassy hues in dye job. Turned out great and something about it made brushing my hair much easier.

I love this product!!!! I was using Matrix before, and it just did not do the job like this shampoo. It literally takes all yellow and brassiness out of your hair in one use. Leaves your hair soft the value for money although expensive very worth it and the longevity between shampoos it lasts. The scent is good. Very lightweight.

LOVE!! This is the very best purple shampoo ever!! Only slight drawback is that it doesn't provide moisture , and so many of us blondes need that. I would say overall though it is truly amazing!!

This is a great product for light blondes and highlighted hair.A little goes a long way so it lasts a long time.Once a week I put a drop mixed in with shampoo and it instantly brightens my highlights.

I have dark brown hair with highlights. The highlights get brassy and need some repair between toners at the salon. This works well for the lightest sections and they do look “cooler” again. However…it’s just ok for the sections that aren’t super light. Honestly, to John Freida Blue Crush works better on my highlighted brown hair…blue just cancels out orangs brassiness than purple does.

I’ve been using Olaplex Blonde Enhancement for a few weeks, and I’m so impressed! It has brightened my blonde hair, eliminating brassiness and leaving a vibrant, cool tone. My hair feels stronger, softer, and much healthier with less breakage doesn’t feel dry. It’s easy to use and doesn’t weigh my hair down. The only downside is the price, but it’s worth it for the results. Highly recommend for anyone with blonde hair since it works pretty well.

Why did you pick this product vs others?:Great product! I love to make my blonde and silver brighter and this works great to brighten and take away the brassiness. Works best if you squeeze excess water out of your hair and apply in sections a little at a time. Really work it into your hair and then let it sit for 10 minutes.

If you’re blonde and tired of brassiness, this shampoo is a game-changer. Olaplex No. 4P tones and strengthens — unlike most purple shampoos that dry your hair out. After one use, my hair looked noticeably brighter, cooler-toned, and felt incredibly soft.It lathers nicely and you only need a small amount. I leave it on for about 3 minutes when I want a more subtle tone, and up to 5 for a cooler, icy blonde. Plus, it smells amazing!Tip: Use it once or twice a week between regular washes to keep your blonde fresh without over-toning.Definitely worth the price if you want salon-quality results at home!
