What’s the best purple shampoo for blonde hair?

Whether your blonde hair is natural or carefully crafted by your stylist at the salon, keeping your color looking bright and vibrant is key. If you’ve heard about purple shampoos for blondes, you might be wondering how they work and whether you should add one to your hair care routine. To help you make the right call and keep your blonde looking its best, we’ll walk you through everything you need to know, including:

What is purple shampoo?

Purple shampoo is specially formulated to deposit colored pigment onto your hair with every wash. These types of shampoos were created to address brassiness, which is an unwanted yellow tone that occurs in gray or blonde hair.

The reason why purple shampoos work to improve brassiness in gray and blonde hair has everything to do with color theory. Complementary colors are opposite one another on the color wheel, and when you mix them, they actually cancel each other out. Have you ever tried a green-tinted concealer to help neutralize redness in your skin? These color-correcting concealers work because green and red are complementary colors, and purple shampoo works in much the same way. Because purple and yellow are complementary colors, washing your hair with a purple color-depositing shampoo helps neutralize the yellow tones that can make blonde or gray hair look brassy.

Why do I need purple shampoo for blonde hair?

When you use purple shampoo on blonde hair, it doesn’t technically lighten your hair, but rather, it helps it appear brighter by canceling out those yellow, brassy tones. Blonde color-treated hair can start to look brassy over time as the color fades, and using a color-depositing purple shampoo can help improve the appearance of its color and help extend the time between those highlighting appointments at the salon. Natural blondes may also notice brassiness from external factors such as sun exposure, pollution, and mineral buildup from hard water. Most purple shampoos are meant to be used once or twice a week or as needed in alternation with your daily shampoo.
