Highlights are one of the best ways to add multidimensional texture, subtle or dramatic, to your hair color.
If you have blonde or silver highlights on your hair, you’ve probably heard that purple shampoo should be used for keeping it fresh.
But how often should you use purple shampoo for highlights? Well, wonder no longer. This question is answered in detail below.
How Often To Use Purple Shampoo on Highlighted Hair?
It is recommended to start using purple shampoo once in every other week, and if your hair still has unwanted brassiness, increasing the frequency once or twice a week is acceptable.
If you have too brassy blonde balayage highlights you can use it up to three times a week but not more than that.
On days when you don’t use purple shampoo, use a non pigmented shampoo and conditioner suitable for your hair type.
You should start with lowest frequency and adjust the frequency depending on the result because overusing purple shampoo can dry out your hair.
Since purple shampoo coats your hair in pigments, using it frequently can cause buildup, leaving your highlights looking darker.
What Does Purple Shampoo Do To Highlighted Hair?
Purple shampoo is a type of shampoo that deposits pigments onto your strands that do not lighten or darken your hair but neutralize tone issues.
If you remember the color wheel, you’ll recall that purple and yellow are directly across from each other. That means these colors are complementary and cancel each other out.
Purple shampoo balances out yellow or brassy tones from highlighted hair that can occur when washing your hair, prolonged sun exposure, or regular swimming in chlorine-treated water.
Purple shampoo acts like a toner for highlights, blonde, silver, and gray hair colors, removing unwanted brassiness.
What Will Happen If You Overuse Purple Shampoo on Highlights?
Overusing purple shampoo can leave a purple tinge to your highlighted hair.
Washing your highlighted hair too much with purple shampoo will leave your hair feeling dry, and instead of being silky and lustrous, you’re likely to run into more frizz and could see more split ends than usual.
If you notice any purple stains on your hair, stop using purple shampoo until it fades, and then start using purple shampoo again gradually.
So, use purple shampoo on your highlighted hair at least once every two weeks, but no more than three times a week. This will ensure your highlights look their best.
Now that you know more about purple shampoo and how often to use it, let’s answer some common questions about it.
No. The purple shampoo will not lighten your highlights because it contains no chemicals that change your hair color. Instead, it will simply counter the ugly yellowing that lightened hair color experiences.
No. As long as you only leave it on for the recommended time, purple shampoo cannot alter your hair color, including turning it purple. However, leaving it on too long can give your hair color a purple tinge, but this isn’t permanent and will fade with your next regular wash.
Don’t use purple shampoo within one week of coloring your hair appointment. This is because the purple pigments will affect your hair color’s true hue and prevent the colorist from understanding your color and tone completely.
