Now, this is where it gets tricky - if you’re asking 'what will happen if I put purple shampoo on red hair?', the answer largely depends on the shade of your tresses.

Generally, the purple shampoo won’t drastically change the colour, but it may make it a shade or two darker.

How To Use Purple on Red Hair

You may now be curious about how to put purple shampoo to good use on your red hair. It's simple! If your hair needs some tinning, follow these steps.

Apply Your Shampoo

It is not necessary for red hair. However, if your hair starts to look brassy or your scalp becomes irritated, you may want to switch to purple shampoo.

Although shampooing is primarily about cleaning the scalp, it's essential that you fully cover your hair with a purple shampoo. This will ensure that the purple pigments are absorbed into all your hair.

Wait It Out

The wait time is another difference between regular shampoo and purple shampoo. It would help if you let it sit on your hair for at least a few minutes after applying it.

Apply Your Conditioner

Then, apply your conditioner. This conditioner will be applied to your hair just like your regular conditioner.

Repeat As Needed

The amount of brassiness in your hair will determine how often purple shampoo should be used. It will depend on which product you are using. Purple shampoos should be used only once per week. Others can be added to your routine several times weekly until you feel the brassiness has gone.

What To Consider When Using Purple Shampoo On Red Hair

  • Purple shampoos can cause hair to turn blue if left on for too long. If you accidentally get blue hair locks for the subsequent two washes, switch to your regular shampoo.
  • After washing your hair, dry the towel and absorb any excess water. Wrap the towel around your shoulders and neck to prevent any staining. To preserve the color, we recommend that you let your hair air dry.

Other Color Shampoos To Use on Red Hair

Although it is best to stay clear of green shampoos, there are still options for red hair that use purple shampoos.

Three colors are suitable for redheads:

  • Red shampoo: This shampoo is best for red hair. It enhances red pigments and increases vibrancy. UV protection is also included in red shampoos.
  • Pink shampoo: Pink supports red hair colors because they are next to one another on the color wheel. This extra tint is best for red hair. Consult your stylist if you have red highlights, as the shampoo can alter the color of the hair.
  • Clear shampoo: This is the non-tinted version of color-treated shampoo. Because it retains the vibrancy of all red hair colors, this product is suitable for all.
