Who should be using purple shampoo?
Just because you see a radical color dye on the shelf, doesn't mean you should jump at the chance to use purple shampoo – it's designed for a specific segment of hair color users. If you're someone who has dyed their hair gray, silver, blonde or even platinum white blonde, then it's likely that purple shampoo should be in your arsenal of hair products. That being said, while purple shampoo is used for blondes, it can also be used by people with lightened balayage or ombre hair, as they might have to deal with stubborn yellow hues as well.
How does purple shampoo work?
Purple shampoos are designed to neutralize the yellow tones that can develop over time. These brassy hues are generally the result of sun damage, chlorine from swimming, or mineral impurities in water. As purple is the opposite color to yellow on the color wheel, it means that it will work to counteract and eliminate the yellow tones that are present.
How often should you use purple shampoo?
The answer to this question is entirely subjective and generally depends on how often you already wash your hair as well as the color of your hair. Purple shampoo for blonde hair, for example, can be used slightly more often than for silver hair since the color isn't as bright and striking. It's important to keep in mind that the more often you wash your hair, whether with purple toning shampoo or ordinary shampoo, the faster the color is going to drain from your hair. So, a general rule of thumb is to try and wash your hair as seldom as possible, at least if your goal is to keep your hair looking as silver, gray or blond for a long time!
