What Is Purple Shampoo Bar Technology?
Purple shampoo bar technology is a hair care technique where you routinely use concentrated purple pigments in solid bar form to neutralize unwanted yellow and brassy tones in blonde, silver, and gray hair.
This is called purple toning, and it helps you maintain professional-level color correction at home. This will help your hair color stay vibrant and get you compliments from everyone.
Through this color-correcting process, you can get access to salon-quality results from concentrated formulas that deliver up to 10x more active ingredients than traditional liquid shampoos.
A purple shampoo routine helps you build (or improve) your hair maintenance strategy — the right way and allows you to:
- Neutralize brassiness with concentrated pigments: During this process, you’ll use ultra-violet pigments that counteract yellow undertones more effectively than liquid alternatives, and eventually, you’ll come out with cooler, ashier tones that look fresh from the salon.
- Strengthen hair with premium ingredients: Identify which ingredients (biotin? keratin? vegan proteins?) help maintain healthy hair while toning. The global shampoo bar market was valued at $11.03 billion in 2024 because people want better results.
- Save money while getting better performance: By using purple shampoo bars, you’ll discover that one bar equals 2-3 bottles of liquid shampoo, making them incredibly cost-effective for regular toning routines.
Pretty cool, right?
