Stylist recommended
I recently had my hair lightened to begin the process of growing out the grey. My hairstylist recommended the Olaplex No 4P to prevent the brassy. I'm happy with it so far. I have used the No 0 and No 3 for years.

Great
I like an ashier blonde from my purple shampoo and this does it. It feels subtle but powerful, not like some that have a narrow window of being not effective versus too aggressive.

Working great so far
Recently hot highlights on my red hair, and the toner is gentle enough to use daily. Seems to be working great!

Tones brassy color
This is great shampoo that works wonders on blonde hair. Eliminates brassy tones. Don't leave in too long or hair turns lavender (but washed out with next regular shampoo).

Great shampoo
My grey hair was dry and dull from regular shampoo. Olaplex 4P Toning Shampoo made my hair soft and shiny.
