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.
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.
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.
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.
It’s award-winning and tones while it cares. The Blacklight Blonde Science Blue Shampoo won Best Shampoo for Blonde Hair at the 5th Annual Chatelaine, FASHION and HELLO! Canada Beauty Awards. It’s sulfate-free and colour-safe, with a hydrating base of squalane, moringa and argan oils that neutralizes orange without drying out lightened hair. Developed in our Montréal lab.
