FAQs

Violet Shampoo

What does Violet Shampoo do?
Violet Shampoo helps neutralize unwanted yellow and brassy tones in blonde, highlighted, grey, or white hair. The violet pigments work opposite yellow on the color wheel, helping restore brighter, cooler-looking blonde shades.

How often should I use Violet Shampoo?
Most people use violet shampoo 1–2 times per week to maintain tone. If your hair is very brassy, you can use it slightly more often until the desired tone is achieved.

How long should I leave Violet Shampoo in my hair?
For best results, leave the shampoo in your hair for 1–3 minutes before rinsing. This allows the violet pigments to effectively neutralize unwanted yellow tones.

What makes Blacklight Blonde Science Violet Shampoo different?
Blacklight Violet Shampoo is powered by VIO technology, a blend of advanced skincare-inspired ingredients including squalane, moringa oil, açai extract, and argan oil. This formula not only neutralizes brassiness but also hydrates, smooths, and strengthens hair for healthier-looking blonde results.

Does Violet Shampoo dry out hair?
Some toning shampoos can be drying, but this formula contains nourishing oils, antioxidants, and essential fatty acids that help maintain moisture, leaving hair soft, shiny, and balanced.

The Science

A synergistic blend of skincare actives and superfoods

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.

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.

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.

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.
