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

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.

Excellent for keeping blonde or highlighted hair free from yellow tones. It leaves hair soft, shiny, and with a more even color. A very high-quality product.

Tones brassiness fast and leaves my hair soft, not stripped. It’s a bit pricey, but a little goes a long way, so one bottle lasts. Keeps my hair healthy and light — no heavy buildup. Worth the money for bright, healthy blonde!

This is my go-to purple shampoo to help tone my colored-blonde hair. It keeps my hair from getting that "brassy" look. You could use it every day, but I actually do not. Once or twice a week gives my hair plenty of lift to the color and it helps to keep my blonde tone longer between color treatments. My hair is long and I only have to use about a quarter-size amount each wash, which also makes the bottle last longer! I love that this shampoo doesn't make my hair dry and it's also not oily at all. Yes, it's a little pricier for the amount that you get, but it's well worth it!

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, John Freida Blue Crush works better on my highlighted brown hair…blue just cancels out orangs brassiness than purple does.

Ok, i’ve used purple shampoo for over 15 years, this is hands down the best i’ve ever used. My hair turned to the silvery ashy color i wanted. It’s expensive but i’ll buy this again and again. My hair is also softer and looks healthier. It’s a perfect product.

So gentle with the hair, leave my hair clean and soft, smell so good

This is my go to for when I’m blonde. It is pretty drying but the toning is too good to use anything else. I was my hair about once a week so one bottle will last me a while.
