Olaplex Nº.4P Blonde Enhancer Purple Toning Shampoo: Neutralizes Brassiness & Strengthen | Repairs Damages & Hydrates Hair | For Coily, Curly, Straight, and Wavy

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.

Have used it now like 4 or 5 times leaving it on from 5-10 minutes. Great toner. A little goes a long way even thought the bottle itself isn’t huge!! Really great foaming quality. Looks healthier from it too (shinier, softer and a more ashy blonde for my highlights). Not to mention it smells great.

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

Great shampoo works great and makes my hair lighter and helps bring back the silver color to my hair and not the brassy color

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.

My hair is naturally brunette with subtle white stripes, effectively neutralizing yellow tones. It has a mild odor, causes no scalp irritation, and leaves my hair shiny and healthy. It works exceptionally well.

Love love love the color. My hair is soft and skells so good!

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.

👍🏻

This it potent! Use with caution! However, it does exactly as it states and will tone your skin (& your hands + forehead). I use is sparsely every fortnight and I absolutely love it.
