This is my favorite purple shampoo. It tones brassiness in just one wash and leaves my hair feeling soft, not stripped. I use it twice a week and it keeps my color looking fresh between salon visits.

Nathalia

I’ve used so many purple shampoos over the years, and OLAPLEX 4P is the first that tones evenly while actually improving my hair’s texture. No harsh scent, no dry ends, and it doesn’t over-tone or turn my hair purple. My icy blonde stays vibrant, shiny, and healthy.

I love how pigmented this shampoo is it neutralizes yellow tones fast. I leave it on for 3 minutes and my hair always comes out cooler and brighter.

As someone with platinum blonde hair, I struggle with brassiness. OLAPLEX 4P completely changed that. It leaves my hair clean, soft, and perfectly toned without any dryness. Plus, it smells amazing and lathers nicely. Worth every penny.

Great for maintaining cool blonde shades. No buildup or dryness just clean, bright hair.

Kristen

This is hands down the best toning shampoo I’ve tried. It keeps my silver-blonde hair from going yellow and strengthens it too. Perfect for highlighted and bleached hair.

Isabelle

This shampoo helps my balayage last longer and look better. I use it once or twice a week, and it keeps my color salon-fresh. My hair is softer, more manageable, and noticeably less brassy. Plus, it’s sulfate-free, so it doesn’t strip my hair.

Charity

Neutralizes brass and adds shine. A must-have for blondes!

M
Mimi

My stylist recommended this and it did not disappoint. I leave it on for a couple of minutes and it tones beautifully without turning my hair dull or purple. It’s made my highlights pop and my hair feel stronger. This is now a permanent part of my haircare routine!

G
Giada

I’ve used this for a few months now and the difference is clear. My blonde looks brighter and healthier, and it doesn’t irritate my scalp like other purple shampoos.
