FAQs

Violet Duo Jumbo Size

Are purple and violet products the same thing?
Yes — despite the different names, they do the same thing: both use purple pigment to cancel out yellow, brassy tones in blonde or gray hair.

Who is the Violet Duo best for?
This duo is formulated for blonde or lightened hair with brassy or yellow tones. It's ideal if your hair looks warm, brassy, or lacks the cool, bright blonde you want.

Will this weigh down fine or lightweight blonde hair?
No. The formula is designed to tone without heaviness, so hair stays soft and bouncy without feeling weighed down or dull.

Can I use this if I also use a hydrating or repair shampoo?
Yes. Many people alternate the Violet Duo with a hydrating or repair shampoo throughout the week to balance brass control with moisture or strength needs — tone one wash, hydrate or repair the next.

Is this safe for color-treated or chemically lightened hair?
Yes. It's specifically formulated for blonde and lightened hair, and it's free from sulfates, salts, parabens, formaldehyde, MI/MCI, gluten, and animal by-products.

My blonde looks brighter and cooler after one wash. No dryness, just soft, shiny hair. Love this violet shampoo!

The Science

A synergistic blend of skincare actives and superfoods

Argan Oil

Known as ‘liquid gold,’ argan oil is rich in linoleic acid and vitamin E, replenishing the fatty acids and moisture stripped by bleach and colour to make blonde hair softer, shinier, golden.

Moringa Oil

Rich in antioxidants and oleic acid, moringa oil strengthens blonde hair against the everyday stressors that cause colour fading and brassiness. Because blonde hair shouldn’t be fragile hair.

Açai Extract

A superfood rich in polyphenols and omegas, açai fruit smooths the cuticle and enhances elasticity to fight the frizz lightening can cause, protecting blondes from brittle strands.

Squalane

A must-have skincare active for hydration, squalane is a biomimetic, mimicking the scalp’s natural sebum to rehydrate the hair and condition coloured strands from the inside out.

Perfect for my highlights

I have a LOT of long highlighted hair so I was always going through the smaller bottles. This size makes so much more sense for me and keeps my blonde looking fresh between appointments.

Finally in a big size

I've been using the violet shampoo and conditioner for a while so I was really happy to see the jumbo bottles. Keeps my blonde bright and these will last me forever lol.

So worth it

My platinum gets yellow pretty quickly and I use this about once a week. Tones really well without leaving my hair feeling dry. Love having the bigger bottles now!
