Purple Shampoo vs. Blue Shampoo — What's the Difference?
Purple cancels yellow. Blue cancels orange. Here's exactly which one you need — and how often to actually use it.
Toning shampoos are the most-misused product in the average bathroom. Here's what they actually do.
Purple shampoo
Deposits violet pigment to neutralize yellow tones. For platinum, ash, vanilla, and cool blondes.
Blue shampoo
Deposits blue pigment to neutralize orange tones. For brunettes with highlights, brondes, and warmer blondes that pull brassy.
How often
Once a week is plenty for most clients. Over-use turns blonde grey/lavender and brunette muddy.
How to use
Apply to wet hair, leave on 3–5 minutes, rinse thoroughly. Follow with regular conditioner.
The salon backup
A professional gloss every 6–8 weeks does what shampoo can't — real tone correction, real shine, real longevity.
