What Exactly Is Purple Shampoo And Its Working Principle?

Purple shampoo is a toning shampoo that contains a violet color pigment helping to neutralize undesirable yellow tints on blonde, platinum, natural gray, dyed hair, or bleached hair to avoid the appearance of unwanted dull blonde.

What is the working principle of purple shampoo? The answer is that it depends on the color theory, which states that when two contrasting hues are mixed, they delete each other.

Is It Acceptable To Let Purple Shampoo Stay On Red Hair?

In general, you can use purple shampoo on your red hair, and the result is the same as that of blonde hair.

It is because brassiness in your red hair looks orange, which is in the same color family as yellow. Therefore, purple pigments help to cancel this color.

In other words, purple shampoo is intended to eliminate undesirable yellow or orange tones from your hair. Also, the purple shampoo can improve the hue and give it less drab.

If your red hair has gone yellow as a result of coloring, you should use a purple shampoo because it will restore the color of your hair to its original state.

Bring red hair’s vivid condition

Red hair is frequently brassy, so keeping it vibrant and natural-looking.

When you use purple shampoo, the purple pigments will penetrate the hair cuticles, remove the yellow tones, and stay there even after shampooing. Once the dull yellow color is removed, it will leave the hair shiny, look better and last longer between salon appointments or at-home dyeing sessions.

However, purple shampoo may have a distinct effect on different types of dyed red hair.

Warnings: Purple shampoo on dark red hair

Purple shampoo is not suitable for dark red hair because this shampoo neutralizes the yellow pigments in the hair strand. It is better for the lightest tints as yellow is exposed once you bleach the hair to obtain lighter hair hues.

Whatever powerful purple shampoo may appear, it will not be able to eliminate brassiness in dark and medium hair, which seems to pull red and orange tones. Some toning solutions will work better on such underlying pigments.

In addition, if you have a dark mahogany hue that resembles black or dark brown, your brassiness most likely appears as reddish copper streaks rather than yellow.

In this case, you should look for a blue shampoo to help neutralize the brassiness in the deep red strands because blue is the opposite of orange in the color wheel. Thus, if your hair is darker red, skip the purple shampoo.

What Are The Methods Of Applying Purple Shampoo To Red Hair To Achieve The Best Results?

Before applying purple shampoo, many people frequently wash their hair with regular shampoo to remove accumulated oil and dirt. However, this is unnecessary because purple shampoos can work on your hair just like regular ones.

Let’s take the following steps to apply purple shampoo to red hair and get the best results:

  1. Apply a sufficient amount of purple shampoo to your hand comparable to your hair’s length, then apply it to wet hair.
  2. Apply it towards the ends of your hair and move up to your scalp. By doing so, you may ensure that you have distributed the pigments evenly.
  3. Allow it to sit in your red hair for 2-3 minutes. If you have many brassy tresses, you can let the purple shampoo stay on your red hair for 4 minutes. Depending on the product’s instructions, the waiting times can vary.
  4. Shampoo your hair carefully to get rid of any remaining shampoo.
  5. Apply conditioner to your hair.
  6. Allow 3 minutes for the conditioner to soak into your hair before rinsing with warm water.

You can do the process again as necessary until your hair no longer appears colored.

Note:

  • For daily shampoo

You can use purple shampoo to replace your regular one daily till the orange shades disappear. After that, switch back to your regular shampoo.

You can reapply the purple shampoo every day if you realize brassy tresses are reappearing.

  • For treatment shampoo

It is essential to follow the instructions of the manufacturer because too much of it can significantly change your hair’s color. The frequency of reapplication ranges from 1-2 times per week to once every three weeks.

Importantly, you should use regular shampoo between those washes if you use treatment one to maintain healthy hydration levels in the hair.

How Frequently Should You Utilize Purple Shampoo On Your Red Hair?

First, the frequency of use is determined by what you intend to use the purple shampoo for.

  • If you only want to maintain the color of your hair, once per week will suffice.
  • However, to remove unwanted shades, you may need to raise the frequency to twice per week, as well as the dose.
  • In case you have never used purple shampoo before, we suggest using it only once per week at first. As a result, you may be able to put the procedure under your control and steadily strip off the hue until you attain the ideal shade.

Second, the product itself will also determine how frequently you should use purple shampoo.

Many purple shampoos should be applied once per week, while others are recommended to be incorporated into your routine several times per week till brassiness is disappeared.

The amount of brassiness in your red hair also determines how frequently you should use this shampoo.

Last but not least, remember that you should not use purple shampoo in place of your regular shampoo because it has a lower cleaning ability and a harsher composition. As a result, it is unsuitable for daily use.

Several factors affect the frequency that you should apply purple shampoo.

Once washing your red hair using purple shampoos, you should be mindful of the time because allowing the formula to remain on your hair for too long may result in a blue shade.

Frequently Asked Questions

Is Purple Shampoo Bad For Your Red Hair?

First, the cool purple pigment in this shampoo will not harm your red hair. However, as we mentioned above, if you let it stay on your tresses for too long, those pigments may go too far and convert your tresses into a tint.

Hence, keep in mind how long you let the purple shampoo stay on your hair. It is best to follow the manufacturer’s instructions.

However, unless you are familiar with the product, you should use it for a shorter time to see how your hair reacts. Gradually, you can leave it on for extended periods.

Second, because the purple shampoo’s formula is quite harsh, leaving it on your hair for too long can cause it to become dry and frizzy.

What Makes Red Hair Color Fade So Quickly?

Since the color molecules in red pigment are relatively more extensive than in other hues, the first few times you dye your hair red, the pigment will not wholly enter the hair cuticle and discolor your hair.

It implies that it may slip out of the hair cuticle with each rinse.

Besides, several other factors are making your red hair fade so quickly, including UV radiation, too much shampoo (the less you shampoo your hair, the more vibrant the color will remain), harsh shampoo (shampoos coming with sulfates and salts are known to damage colored hair), and chlorine and saltwater, etc.

In general, red hair color will fade noticeably within four weeks. Therefore, it may take several efforts to get the pigment to adhere to your hair. Despite that, red hair is still easy to fade and appears brassy or orange.
