Purple Shampoo Explained: What It Does and Who Needs It

Whether you’ve got icy blonde or are going full silver glow, purple shampoo is the secret behind those brass-free and radiant tones you see. But what exactly makes it special? Who needs it? How can you get the most out of it without going overboard?

What Is Purple Shampoo and Why Is It Purple?

This little secret unveils the whole theory about purple shampoo. On the color palette, purple is directly opposite yellow. When you put purple and yellow together, they work to remove brassiness. It also helps to restore your tone to balance. For those with blonde, silver or icy shades, purple shampoo is exactly what you need to bring brightness back to your hair.

During wash sessions, purple shampoo is a mini-toning therapy. It gives you that just-from-the-salon color and removes brassiness when used correctly.

Who Needs Purple Shampoo?

Purple shampoo is not for all—however, it's a savior for some. If your hair checks any of these boxes, then purple shampoo is for you.

Your hair is dyed or color-treated blonde hair.
Silver or platinum.
Natural white or grey tones (purple shampoo for grey hair).
Balayage or ombré with lighter ends.
Blonde highlights or lowlights.

If you want to have a cool tone that is vibrant, purple shampoo doesn’t only cleanse—it helps remove brass and makes color last longer. It is particularly helpful for grey-haired people as it stops yellowing that tends to result from sun damage or hard water. It's a subtle means of adding shine and depth, making purple shampoo for grey hair a mainstay with many older users.

What Makes a Great Purple Shampoo?

Not all purple shampoos are created equal. While the color is the main attraction, the supporting actors are what make or break your hair's health.

A good purple shampoo should:

Contain a rich, violet color.
Not include any harsh chemicals.
Supply moisturizing and smoothing ingredients.
Suits your hair texture.

For hair that is colored, prone to dryness or textured with a sulfate-free shampoo, these challenges are taken care of. A purple shampoo that contains sulfate can strip your hair’s natural oils and color, leading to hair breakage.

GK Hair’s Silver Bombshell Purple Shampoo is sulfate-free with Juvexin, a keratin protein complex, which smoothes and builds.

Beyond toning down brass, GK Hair’s Purple Shampoo also keeps your hair healthy and shiny without weighing your hair down.

How Often Should You Use Purple Shampoo?

A question stylists constantly hear is—how often do you really need to use purple shampoo? The truth is, it depends on a few things, and that is: your hair type, how deep your hair color is and how fast brassiness sets in.

Here's a rundown:

Icy Blondes and Platinums: 2–3 times a week.
Grey Hair Purple Shampoo: Weekly.
Warmly Colored Blonde or Highlighted Hair: Every 7–10 days.
Dry or Curly Hair: Every 2 weeks.

Overuse of purple shampoo has a side effect. When you do that, it can sometimes leave a faint purple tint or make your hair dry. The way to escape this is to follow up with a rich moisturizer like GK Hair’s Deep Conditioner Hair Treatment or Moisturizing Conditioner.

How to Use Purple Shampoo Effectively

Here’s how to work the purple shampoo into your hair care routine:

Wet your hair thoroughly, this allows the even distribution of the shampoo.
The application of purple shampoo should be from roots to ends. Use a comb for even distribution.
Allow shampoo to sit for 1-5 minutes.
Ensure to rinse thoroughly, this helps to remove pigments lurking around.
Follow up with a moisturizing conditioner.

For more shine, just add a few drops of GK Hair’s Serum Argan Oil. It helps seal in moisture and leaves your hair looking freshly toned and soft.

The Water, Environment, and Maintenance Factor

Purple shampoo is best utilized when paired with the following brass-preventing habits:

Utilize filtered water where available. Hard water minerals have a tendency to deposit yellowing hues as they build up over time.
To remove product build-ups, shampoo your hair every 4-weeks. This helps dilute the actions of the purple shampoo.

Keeping cool-toned hair requires personal commitment, but the right habit helps make a difference.
