Review: The Secret to Vibrant, Strong Blonde Hair—Free of Yellow Tones - Olaplex No. 4P Blonde Enhancer Toning Shampoo stands out as one of the best purple shampoos on the market [1]. Unlike other toning products that tend to dry out the hair, its highly concentrated formula effectively neutralizes unwanted brassy tones from the very first use while maintaining essential hydration [1, 5, 6]. Thanks to the brand's patented technology, this product not only corrects color in blonde, bleached, or gray hair but also repairs hair bonds damaged by chemical processes [1, 2]. It is an exceptionally effective choice for those looking to maintain a luminous, clean color with a completely healthy appearance
Review: It works! - Excellent product! I have used Sun-In with peroxide on my hair for a couple of years now and get a better effect than streaking with foil. This shampoo calmed down the blonde brass, whitened the gray, and the brown hair melds beautifully. It also left my hair very soft. Love it!

## Questions & Answers

**Q: Is this shampoo okay for Type 4 coils?  My grey hair looks dull and I was told a purple shampoo would help.**
A: I have thin blonde, but (when it's humid) frizzy hair.  After coloring my hair, I got in the shower, rinsed out the dye & proceeded to wash my hair with #4P, to tone down the brassiness of the color.  When I went to rinse the shampoo out, I couldn't believe how stiff & tangled my (chin length) hair was.  I could barely get my fingers through my hair.  I, then, put the conditioner on which I use every day.  It is "Not Your Mother's" (purple).  After leaving that one for a couple of minutes, I rinsed & got out.  I was not too fond of the #4P but it did tone down the brassiness.  I would look for a brand that removes the "yellow" from grey hair.  It should give it some shine.  Good luck.

**Q: Has anyone bought this 4P product recently?  All the reviews seem to be a few years ago. Wondering if this is the real product?**
A: This is! It doesn't take all the brass out of my hair but I do like it just as much as the rest of my olaplex products.

**Q: puedo usarlo en cabello decolorado con tono cobrizo naranja ?**
A: Si crees que el color te quedó muy fuerte este champú te ayudará a bajar el tono

**Q: Is this 2 bottles? Shampoo and conditioner for the price? Or just the shampoo?**
A: Just the shampoo. Amazon prices are much lower for this brand than at my salon.

### ⭐⭐⭐⭐⭐ Good Product
*by L***S on April 1, 2026*

It definitely changes your colored hair so be sure NOT to leave it on long. I have dyed blonde hair but it had turned brassy from our well water. My hairdresser suggested I try this, but it really turned my hair silver from leaving it on too long. Fortunately, it was almost time to get it re-colored. Lesson learned. It’s still a great product and you don’t need to use much as a little goes a long way. I think this would be really great for white hair.
