What it is: A purple shampoo that neutralizes brassiness and targets everyday damage to reveal bright, evenly toned, and shiny blonds and grays.

 

Hair Texture: Straight, Wavy, Curly, and Coily

 

Hair Type: Fine, Medium, and Thick

 

Hair Concerns:
- Brassiness

- Color Fading

- Color Sage

 

Key Benefits: 
- Brightens hair color and enhances shine

- Neutralizes unwanted yellow tones and brassiness

- Cares for everyday damage and defends against future breakage

 

Highlighted Ingredients:
- Bis-Aminopropyl Diglycol Dimaleate: Rebuilds broken and weakened bonds.

 

What Else You Need to Know: This ultra-concentrated purple shampoo evens the tone of natural or color-treated blonds or grays—neutralizing unwanted brassiness for bright, shiny hair. The hydrating lather gently cleanses hair and enhances softness while targeting everyday damage for stronger, more resilient hair in one wash.

 

Fragrance Description: Revitalize your senses with a bright burst of grapefruit zest, the crisp scent of sugared mint, ginger, and a sophisticated, grounding base of crushed sage.

 

Clinical Results: In a test, compared to top purple shampoos, results showed:

- 3X brighter hair

 

In an independent consumer-perception study of 60 women with bleached/color-treated blond hair, when used as a system with No.5P (sold separately):

- 90% agree hair was less brassy

 

In a test, results showed the shampoo:

- Repairs everyday damage in 1 wash and strengthens hair at a molecular level

Listen to the other reviews….
I myself should have believed the other critical reviews. This product does absolutely nothing for your hair! It’ll only leave you with stained fingers and nails. A total waste of $$$.

DO NOT BUY
I’ve been using this in tandem with the conditioner, and it dyes not only my hair purple but my scalp is purple, too. I use latex gloves to wash my hair anyway, but I know it would dye my hands. I switched from using Verb to try something new but man I regret that decision. It also makes my hair so dull looking, like my blonde is not vibrant at all, I hate it 😭 People have asked me if I dyed my hair purple, that’s how noticeable it is. I have natural blonde hair that changes lightness with the seasons, getting to platinum blonde during the summer. I am not buying this ever again, do not recommend!

Don’t use unless you want to become a purple mess
Absolutely horrible product. Turns your hair and nails purple for two days even with scrubbing salt and exfoliate

Not that good
I have been searching for more affordable alternative to the Kerastase purple line. Unfortunately this is not it :( Kind of drying, tangles hair awfully and doesn’t leave that bright hue like the kerastase does.

Don’t do it
Destroyed my hair. Stained my skin. Do not buy. Get Kerastase instead.

Just went platinum
Love this product! I just dyed my hair a platinum blond so I needed to upgrade my purple shampoo. The difference in before and after is amazing! Wish I took pictures. Just be careful, don't use too much or leave in for too long. My hairstylist also recommend using a shower brush to distrubute it more evenly. After all that, I love using this. So hydrating too!
