We've put together this ultimate guide to help you properly maintain your beautiful color. From understanding what it is and how it works, to how often you should use it - here's all you need to know about purple shampoo for blonde, lightened, or gray hair.

What Does Purple Shampoo Do?

purple shampoo before and after

Purple shampoos contain a purple pigment that neutralizes yellow and brassy tones on lighter hair. The primary reason it has a purple color is that, on the color wheel, it is the direct opposite color of yellow. This means that purple and yellow colors will always cancel each other out.

Purple shampoo is also referred to as toning shampoo, meaning it puts violet or purple pigments into your mane to cancel out yellow or brassy tones. So when you use purple tint on color-treated yellow or brassy tones, it corrects your hair's shade, restoring it to its previous neutral or natural brightness with cooler tones.

Although purple shampoos are mainly famous among blondes, you can also use them on darker shades of blonde or to boost brunette, gray, silver, white, or platinum-colored hair. Purple shampoo is for anyone looking to lower orange, brassy, or yellow tones in their hair hue.

What Happens If You Use Purple Shampoo On Brown Hair?

You can use purple shampoo on darker hair shades. Purple shampoo can help neutralize some brassy tones in your brown hair, as it does with blonde hair. Purple shampoos are most efficient when balancing light, color-treated strands on brown hair.

Although purple shampoo can help hair of any shade look healthier, using a purple shampoo might not be particularly effective if you have full tresses of dark brown hair. But, if you have dark hair with highlights, the purple shampoo will help tone your lightened strands.

Everything from excessive styling heat and UV rays to the presence of some minerals in your water can make your brunette hair brassy with unwanted yellow or orange undertones weeks after coloring. Since purple sits across orange on the color wheel, purple hair products will neutralize the brassy tones and make your hair look fresher.

Using purple shampoo on lightened brown hair or dark hair with highlights will have the same effects as it does on blonde hair. To add a purple shampoo to your hair care routine, just exchange or alternate your regular shampoo for a purple one. This will still clean your hair and scalp like a traditional shampoo, but it has an added toning effect that will balance out color-treated strands.

What Does Purple Shampoo Do To Red Hair?

You may be wondering if you can use purple shampoo on your red hair. Yes, purple shampoo on red hair is perfectly safe. This hair treatment will only help tone your hair hue, not fade. It helps to neutralize unwanted yellow tones as your red hair color begins to fade.

By doing that, your overall hair color will look its best and even last longer between at-home coloring sessions or salon visits. While purple shampoo can help rid your hair of unwanted yellow shades, you shouldn't worry about it removing your beautiful red hair color.

By looking at the color wheel, you will understand what we mean. To get rid of red tones, you will need to use green shampoo because red and green sit opposite one another on the color wheel. However, purple cancels out yellow making it perfect for treating brassiness.

Red hair with blonde highlights may also benefit from purple shampoo, as the highlights may probably get brassy over time. Purple will help zap out that brassiness.

What Does Purple Shampoo Do To Black Hair?

Not hoping to disappoint you, but purple shampoo does nothing to black hair than cleanse it. Regardless of if the hair is color-treated black or naturally black hair, purple shampoo doesn't work to change the color of black. This is because it's not possible to darken black hair any further.

This may not be the case if you have dark brown hair, but black hair has reached its limit of darkness, and purple shampoo will not lighten it. Though if you wash your back hair with purple shampoo, it will help cleanse it as if you washed it with any other high-quality shampoo.

Does Purple Shampoo Damage Hair?

The violet pigment in the purple shampoo will not damage your hair; however, if you leave it on your mane for too long, those purple pigments will handle their job a little more effectively and could turn your hair into a purple-violet color.

So, be cautious of how long you leave the purple shampoo on your tresses. You can leave it on for longer hours once you get familiar with the product and how it reacts on your strands. If you have dry and porous hair, you'll want to monitor the color correction because it will be extra sensitive to the effects of purple shampoo.

How To Use Purple Shampoo

Step #1: Choosing A Purple Shampoo

1. Choose a purple shampoo with thick color and consistency:

A premium purple shampoo should be opaque and not transparent in color. If possible, squeeze a small amount of the shampoo on your fingers before purchasing it to ensure it has a solid color.

2. Purchase a darker purple shampoo for your gray, platinum, or silver hair:

Darker purple treatments, some of which come very close to indigo or blue, work perfectly on gray, platinum, or light-blonde hair. Avoid violet or bright purple shampoos and choose a dark shampoo for pale hair.

3. Select a brighter purple shampoo for blonde hair:

Blonde hair requires less purple coloring to rid brassiness from its tone. Shy away from inky violet shampoos and choose a brighter color to avoid oversaturating your hair. The lighter the hue, the less brassiness it will absorb from your mane.

4. Stay away from purple shampoo if you have dark hair:

Purple shampoo is best if you want to turn brassy blonde or silver hair into a brighter, more neutral shade. It is not as effective on black or brunette hair. If you have darker hair, consider another shampoo treatment.

5. Professional, high quality hair care makes all the difference!

You’ve probably already had this talk with your hair stylists - but using professional high quality hair products truly makes a difference with your hair color longevity, hair and scalp health, texture and overall appearance.

Step #2: Applying Purple Shampoo

1. Wet your hair with slightly warm water:

You need to get your mane completely wet before applying your purple shampoo. Warm water has a soothing and healing effect on your hair. The temperature will help expand your hair shafts and enable them to absorb the shampoo better.

2. Rub the shampoo into your hair:

Apply your purple shampoo to your mane from root to tip. Massage gently as you work the shampoo through your hair, lathering it as you go. Prioritize your roots and your hair's problem areas - yellow or brassy strands you hope to treat with purple shampoo.

3. Leave it on for 2-3 minutes for naturally blonde hair:

If you have warmer, natural blonde hair with mild brassiness, 2-3 minutes should be enough time for the shampoo to do its work. After the time has passed, rinse your hair with cool water. The recommended time may differ slightly from brand to brand; the shampoo may need to let sit for up to 5 minutes.

4. Leave the shampoo on for 15 minutes on brassy or color-treated hair:

If you have just recently dyed your hair blonde or your hair is significantly discolored, let the shampoo sit for 5-15 minutes. This is because your hair may need more time to absorb the tone fully. After the time has passed, wash the shampoo out with cool water.

5. Keep the shampoo in for 30 minutes if you have silver, gray, or platinum hair:

Although people with darker hair may worry about losing their hair color, platinum and silver benefit from leaving the purple shampoo in for longer. Let the shampoo sit in your hair for about half an hour before rinsing, based on how stained or brassy your hair is. You may need to wear a plastic shower cap over your head while you wait.

6. Condition your hair as usual after rinsing the shampoo:

Finish your washing routine with a conditioner to keep your hair moisturized. If you want, you can pair your purple shampoo with a purple conditioner to strengthen the intensity of the tone. However, this could lead to an ashy tone; only use the duo if you want a pale hair color.

How Long Should I Leave Purple Shampoo In My Hair?

If you have never applied purple shampoo before, consider leaving it in for 2 to 3 minutes before washing it off. If you see little or no difference in your hair color after drying it, try 5 to 10 minutes for your subsequent treatment. Unless you have white or gray hair, you shouldn't leave the shampoo on your hair for longer than 15 minutes at a time.

How Often Should You Use Purple Shampoo?

Bear in mind that purple shampoo does not always need to replace your regular shampoo. Use purple shampoo once a week or anytime you notice brassiness. If you do not see any changes after a month, you can always up your hair care routine to 2 to 3 times a week.

If using Goldie Locks® Brilliant Blonde Purple Shampoo - while it can be good to alternate to avoid over toning, this can be used back to back and will not dry out your hair compared to other luxury purple shampoo brands.

Though purple shampoo will not dye your hair, you may discover some lilac tints after you wash if the shampoo is too strong. To stop this, mix your purple shampoo with water in a 2-to-1 ratio and pour it into a spray bottle.

This option is best for people with already warm hair looking to touch up their color. You can alternate your use of purple shampoo with non-tinted (regular) shampoos to keep your hue light and even. Pay close attention to your hair and use your judgment when creating a routine.

When To Use Purple Shampoo After Bleaching?

Avoid washing your mane for the first 48 to 72 hours after bleaching it. This is to give your hair enough time to seal in its new color. If you waited 72 hours before washing your hair after it was bleached, you could use the purple shampoo the next time you shower. If it hasn't been up to 72 hours, shy away from the purple shampoo until your next wash day, so it doesn't potentially ruin your hair tone.
