FAQs
Blue Shampoo

How often should I use the Blue Shampoo?
Use the Blacklight Blonde Science Blue Shampoo 1–2 times a week, not every day. On other wash days, use a sulfate-free shampoo like our Hydrating Shampoo. If orange or copper tones are strong, go up to 3 times a week until your tone is corrected, then return to 1–2 times.

How long should I leave the Blue Shampoo in my hair?
Leave the Blacklight Blonde Science Blue Shampoo on for 1–5 minutes, then rinse and follow with the Blue Conditioner. Start with 1–2 minutes and leave it longer for stronger orange tones. Darker hair can usually take the full 5 minutes.

Do I need blue or purple shampoo?
Choose the Blacklight Blonde Science Blue Shampoo if your hair turns orange or copper, and the Violet Shampoo if it turns yellow. Blue cancels orange; violet cancels yellow. Avoid blue on platinum or very light blonde hair, where it can leave a slight green tint.

Does the Blue Shampoo work on brown or brunette hair?
Yes. The Blacklight Blonde Science Blue Shampoo is ideal for brown, brunette, bronde and dark blonde hair, and for balayage or highlights lifted from a darker base. These shades tend to turn orange as colour fades, which is exactly what blue pigment neutralizes.

What makes this Blue Shampoo different?
It tones and cares at the same time. The Blacklight Blonde Science Blue Shampoo is sulfate-free and colour-safe, with a hydrating base of squalane, argan oil and açai extract that neutralizes orange without drying out lightened hair. It was developed in our Montréal lab with professional colourists, the team behind Oligo Professionnel since 1986.

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.

Doesnt leave my hair dry like others

other blue shampoos left my hair feeling so dry in the past but not this one

Wow Very Impressed

I am someone who is very picky when it comes to toners or toning shampoos. My roots are dyed to level 7 and my ends are level 9 and 10. My goal was to neutralize the brass on my roots (orange) and even out the yellow on the ends. This is the best toning shampoo I ever used. Fanola and Shimmer Lights are super drying, wouldn�t recommend. This product made my ends a nice icy/platinum blonde color. It didn�t neutralize my roots but it made them more vibrant and blended. Im shocked to have found a toning shampoo that makes hair more vibrant and brighter, all past products I used were either too green/blue or dull. This product isn�t perfect (it would be if it tones level 7 and is more hydrating) but I highly recommend it; after 1 use I�m glad to have bought it. Size of bottle is smaller than I thought too but anyways happy.

We truly appreciate your detailed feedback—so glad our Blue Shampoo delivered brighter, more vibrant results while keeping your blonde looking fresh and luminous
