Pureology has recently launched a brand new Purple hair care range for blond hair  - Pureology Strength Cure Shampoo & Conditioner Duo Pack. Here is Pureology's guide to why you need a purple shampoo...

Whether you’re blonde or brunette, if you lighten your hair, you can likely benefit from using a purple shampoo. Using a purple toning shampoo is a key step in keeping your hair color looking fresh, vibrant, and like you just left the salon. Ahead, everything you need to know about how to use purple shampoo.

What is Purple Shampoo For?

A whole host of things—UV rays from the sun, chlorine, mineral impurities in the water—can all mess with your hair color and create those brassy, yellow undertones that no one wants.

And while typically you may see purple shampoo for blonde hair, brunettes who lighten such as with bayalage or ombré can benefit from the toning formula too, since they often deal with the same type of brassiness and color changes.

Why You Need To Use Purple Shampoo

Think back to the color wheel hanging in your elementary art school class: Purple falls directly opposite yellow, meaning it will work to counteract and neutralize yellow-y tones that— especially cool or icy—blondes definitely don’t want.

Enter the Strength Cure Best Blonde Shampoo, which is a purple shampoo with a strong violet toning pigment.

“The purple color comes from a temporary dye molecule that stays on the surface of the hair, helping to fight brassiness and maintain those cool, blonde tones,” explains Pureology Artist Emily Alders. (But don’t worry, it won’t turn your hair purple.)

An added benefit:
Strength Cure Best Blonde Shampoo, is sulfate-free, so there’s no need to worry about it stripping color, and it contains Strength Cure Asta Repair™, a strengthening antioxidant ingredients that helps repair damage and prevent further breakage and split ends.

How To Use Purple Shampoo

How often you use purple shampoo is totally up to you; you can either use it daily or swap it in place of your standard shampoo whenever you feel like your color is starting to go a little brassy or needs a quick refresh, suggests Alders. Use it just as you would any other shampoo—yes, it’s that simple.
