What is Purple Shampoo?

Purple shampoo actually is a shampoo that’s a deep purple color. It’s designed to neutralize any yellow or brassy tones in your blonde, silver, or white hair. The concept is simple and based upon color theory. Color theory states that when you have one unwanted color or tone, you can use the color that’s opposite it on the color wheel to eliminate or neutralize the unwanted tone. This is how purple shampoo works to remove the brassiness from blonde and how it helps to maintain and brighten your blonde hair color.


Tip: If your brassiness appears to have more of an orange tint, a blue-based shampoo may help correct the problem better.

How to Use Purple Shampoo

The most common question asked about how to use purple shampoo is: How often should I use it? Once a week typically works to help keep brassiness from developing, especially if you begin a routine of using the purple shampoo a couple of weeks after initially coloring your hair blonde. If your color treated blonde hair has already turned brassy, you may need to use the purple shampoo every other day until the brassiness is neutralized and your beautiful blonde returns. Frequency really will depend on the level of brassiness.


To actually use purple shampoo:

  • Use as you would your regular shampoo.
  • Apply the purple shampoo to your roots.
  • Massage into the roots and then allow the shampoo through to the ends.
  • Rinse thoroughly.


Remember, the ends/tips of your blonde hair are more porous than the roots, which means they grab and hold onto color faster than the roots. This is why you should always apply hair color as well as your purple shampoo to the roots first. Generally, your roots will appear brassy before the rest of your hair.
Tip: Don’t allow the purple shampoo to sit too long on your hair before rinsing out. If left on for too long, your blonde hair can begin to take on a purplish hue.

Other Ways to Maintain Your Blonde

One of the best ways to keep your blonde hair or blonde highlights looking bright not brassy is to choose styling products that are free from color. Look for clear or white mousses, styling creams, gels, pastes, and sprays instead of products that contain colors like red, blue, or orange. Avoiding styling products with color can help keep your blonde hair from absorbing those tints.

Chlorine from pools and spas can affect color treated blonde hair as well, often tinting it with a greenish hue. Before swimming, wet your hair — wet hair doesn’t absorb as much of the chlorine as dry hair does. After swimming, thoroughly rinse your hair and then wash it with a swimmer’s shampoo to remove the chlorine and keep your blonde from going green. Specially formulated swimmer’s shampoo also will help condition your hair and keep the chlorine from drying it out like straw.
