If you dye your hair blonde, you need a good purple shampoo in your shower kit — no exceptions. Blonde hair often requires a lot of upkeep, and we're not just talking about salon touch-ups. After a few washes — due to harsh chemicals in the water, UV rays, and pollution — it's common for icy or cool blonde hair to start looking brassy or yellow. That's where purple toning shampoo comes in.
No matter what colour you dye your hair, you should use a colour-safe shampoo and conditioner, but the vibrant pigment in purple shampoo specifically cancels out yellow tones — like a colour corrector. This means using it in the shower can help lighten and brighten the hair, even long after you've visited the salon. From drugstore to professional-grade varieties, shop the best purple shampoos ahead.
