Can I Put Purple Shampoo on Dry Hair Without Causing Any Damage?

If you color your hair, you know how important it is to use the right products to keep your hair color looking vibrant and true-to-tone, especially your bleached blonde hair.

You’ve heard that purple shampoo can neutralize brassy, yellow tones, but can you put purple shampoo on dry hair?

Keep reading to learn about purple shampoo and how to use it properly on dry hair.

Can I Use Purple Shampoo on Dry Hair?

The short answer is yes, you can, but we wouldn’t recommend it. Purple shampoo is a toning product specifically formulated for colored hair.

It helps to reduce the brassy yellowish tone of your gray, blonde, brown, etc hair color. Purple shampoos work this way; they use a combination of purple pigments and blue-violet dyes, which neutralize yellow tones.

With that said, using purple shampoo on dry hair can cause excessive dryness and breakage.

More often than not, the damage can be hard to reverse, so it is best to avoid using purple shampoo on dry hair whenever possible.

Think of it this way, dry hair already lacks the necessary moisture and oils, what purple shampoo does is remove more of these oils from the scalp.

This can only lead to further drying of the hair. Applying purple shampoo on dry hair will make your locks more brittle, and the chance of breakage will only increase.

What Happens When You Put Purple Shampoo on Dry Hair?

Effects of Putting Purple Shampoo on Dry Hair

While you can put purple shampoo on dry hair, doing so can lead to worsening your hair damage. This shouldn’t be done, even on hair that has a purple tint.

But why is this happening? Is there an explanation? Yes, there is, and hair porosity is to blame.

The ability to retain moisture and the ease with which moisture can permeate the hair are both due to hair porosity. Genetics, chemical use (like bleaching), and heat use (like blow drying) all affect porosity.

Due to its dry and dehydrated nature, porous hair can absorb the purple pigments in purple shampoo, giving it a purple tint or purple spots.

Additionally, applying purple shampoo to dry hair may not uniformly spread the color pigments, resulting in certain areas of your hair receiving more shampoo than others.
The uneven distribution of the shampoo will cause certain areas of your hair to have a more pronounced purple tone and tint than others, which will not look great.

If applying purple shampoo to dry hair results in an uneven color, reversing it will be even harder.

How To Use Purple Shampoo on Dry Hair?

Using Purple Shampoo properly

To ensure that you get the best results from your purple shampoo, it’s important to follow the following steps. 

Before Using the Shampoo

Before applying the shampoo, wet your hair with warm water and let it sit for a few minutes. Once your hair is damp but not soaking wet you can apply the shampoo. Having your hair like this helps the shampoo spread evenly throughout, allowing for better results with minimal damage.

Shampoo Application

After that, comb your hair with a wide-tooth comb and your fingers to spread the shampoo evenly. It’s important to only apply the shampoo to the mid-lengths and ends of your hair. If you touch the roots and scalp, you have the risk of staining them with a light pinkish-purple hue.

Furthermore, when using purple shampoo on mid-lengths and ends of your hair, only leave it on for the recommended time indicated by the manufacturer.

Leaving purple shampoo on for too long can also cause staining, discoloration, and damage to your hair, which in some instances can be irreversible.


When rinsing out the purple shampoo, use lukewarm water and rinse until the water runs clear.

Caring for Your Hair After Washing

Finally, it is important to use a deep conditioning mask immediately after rinsing out the shampoo. Deep conditioners can help repair any damage caused by the purple shampoo, leaving your hair feeling soft, shiny, and healthy.

So, Should You Use Purple Shampoo on Dry Hair?

While you can technically use purple shampoo on dry hair, it is not advised. If you do so, you run the risk of over-drying, breakage, scalp darkening, and root discoloration.

If you want to retain healthy blond hair and get the most out of your purple shampoo treatment, completely wet your hair and just apply the shampoo to the mid-lengths and ends. Last but not least, be sure to immediately afterward receive a deep conditioning treatment.
