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

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

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!

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.

Where my platinum ladies at? I'm as psycho as they come about wanting zero brass in my hair. I've tried numerous products, and this right here is THE ONE. One wash and my hair is bright white and wonderful. Look no further!

Great size for the price I paid. Has a great scent and didn’t leak. The color matches the picture.

Best purple shampoo I've ever tried. Doesn't turn my hair grey like Prism Lights, and actually works unlike "Not Your Mother's". I have used it every other day without staining. Just mix with your regular shampoo for a more gentle use. My hair feels very dry at first, but if you follow up with a a good conditioner, you shouldn't have a problem. I use the Olaplex No5 and the hair oil, my hair is super soft.

Great product, low to no smell (and Im sensitive to scents) a little water in formula so I need quite a bit for my long thick hair. But since its a sometimes product it fine Great job with minerals and brass. Quickly restored my blonde without drying out my hair

Love it! I have blonde highlights over greying hair and this shampoo made my blonde pieces brighter and less brassy. Use a good hair mask or conditioner with it as it can dry hair out some

Amazing

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

De los mejores matizantes que he encontrado para mis mechas y canas, además de la hidratación que deja en el cabello. Sin duda, sigue siendo la línea para el cabello, favorita para mi.

The Olaplex Nº.4P Purple Toning Shampoo is a high-quality product that effectively helps neutralise brassy and yellow tones in blonde, lightened, or highlighted hair. After a few uses, hair looks noticeably cooler and more refreshed in tone. It lathers well and a small amount goes a long way, which makes the bottle last longer than expected. Despite being a toning shampoo, it doesn’t leave hair feeling overly dry, and it actually helps maintain softness and manageability. Hair feels cleaner, smoother, and slightly stronger over time, which is consistent with Olaplex’s reputation for repair-focused formulas. It works well across different hair types, including wavy and curly hair. The only minor downside is that it can be a bit strong if used too frequently, so balancing it with a hydrating shampoo or conditioner is helpful. Overall, a very effective purple shampoo that delivers visible toning results while still caring for hair health.
