Why avoid leaving the purple shampoo in the hair for long

Being a blonde is not easy because you need to stick to a regimen to maintain the color. A tinting shampoo is the first step to neutralizing or soothing the tone.

What does the purple shampoo do?

When you finally get the cool hair tone you have been dreaming of, the tinting shampoo can help you keep it as long as possible. A tinted shampoo for blond protects your bleached hair from yellowness. It works based on the color wheel theory: According to it, the adjacent colors are harmoniously combined, and the opposite ones neutralize each other. Purple is the exact opposite of yellow. When you apply this tinted shampoo to your hair, it neutralizes the unwanted shades of yellow, red, and orange and brings out the cool tones of blonde.

How does it work?

When applied to wet or dry strands, the coloring agents penetrate the hair. The cuticles slightly open and absorb the tinting pigments. To get this effect, you should leave shampoo or toner on your mane for a particular time.

If you let the product sit for too long, the number of pigments that penetrate the hair exceeds. Consequently, a purple tint becomes more noticeable. Sometimes it can be even gaudy if the composition stays in the hair for much longer than it should.

The process stops after cleansing the hair with shampoo. Then you have to apply the balm and rinse it with cold water to close the hair cuticles. The working principle resembles how hair dyes work.

Tinting substances are quickly washed out of the hair, especially those from the purple and blue spectrum. They are smaller than in a dye, and the chemicals act on the hair not so aggressively.

Another point you should take into account is the purple shampoo composition, which is rather aggressive. It dries out the hair and skin, making your strands brittle and causing skin itching, redness, or even an allergic reaction.

For how long are we leaving the purple shampoo in the hair?

Here I will explain how long you should keep the product on the hair and why. Read on to understand the details.

How long should you wait?

You can keep the shampoo on the strands for up to 10 minutes and rinse it thoroughly afterward. If you regularly use shampoo for blond hair, it will help to refresh the cool tone and get rid of yellowness. Once you apply it, leave it for several minutes to allow the pigments to penetrate your hair.

Manufacturers usually advise leaving the purple shampoo in the hair for 3-5 minutes. During this time, enough pigments penetrate the strands and mask the warm undertones, without giving a purple tint to the hair.

Why can’t you leave it longer?

Here are some reasons why you can’t overtime shampoo:

  • Using too much purple shampoo can cause locks overtoning. I don’t recommend you overuse the product but stick to the producer’s instructions;
  • The percentage on the label shows the amount of tinting pigment in the product. The higher it is, the brighter the color you will get since more tinting agents will penetrate the hair;
  • Another thing to consider is the hair condition. The more porous your strands, the faster the process. This is typical for curly tresses and the mane after aggressive dyeing. Damaged and dry hair also reacts faster to the toner because their scales are open, so the pigments penetrate faster.

Tips on using the purple shampoo

Here are some handy tips to help you use it correctly:

  1. Apply shampoo evenly. This will help you avoid spots and uneven tone.
  2. Always read the instructions for proper use. Follow the manufacturer’s and your hairdresser’s recommendations.
  3. The frequency of use of purple, blue, and lilac shampoos for blond depends on the quality of your hair. Professionals usually recommend using it once or twice a week. Remember that the main task of tinted blond shampoo is to tone the hair, so you should still choose other hair care products such as moisturizing or strengthening shampoos for your everyday routine.
  4. Choose the right shade of purple shampoo depending on the color of your hair. The more yellow it is, the more intense shampoo you need. I recommend starting with low-percentage options and gradually moving up. This way, you won’t turn into an eggplant at the first toning.
  5. Keep in mind that if you have fine or sparse hair, a tinted shampoo with a lighter shade and less pigmentation will work better. Shampoo with a high amount of pigments can color the hair if you use it daily. For example, if you use dark purple tinting shampoo every day, your chevelure can gain a light purple hue. However, using shampoo once a week should not color your hair.
  6. Don’t forget about gloves and a comb. They will help to apply shampoo evenly.

FAQ About Purple Shampoo Left on Too Long

There might still be questions you would like to ask. Here are the most common ones to prevent any confusion.

Should I use the clarifying shampoo before the purple shampoo?

This is one of the use cases. It can help you get a more pronounced and cool blond if you didn’t lighten the locks for a long time. This is where the purple shampoo can’t cope on its own. In such a situation, you can apply the clarifying shampoo before the purple shampoo once every 2 weeks.

Can the purple shampoo damage your hair?

Yes, it can dry out the hair and make it split and brittle. The product can also irritate the scalp and cause dandruff.

Does the purple shampoo cause hair breakage?

The purple shampoo dries out the hair and makes it more vulnerable but not as much as when you dye it. To avoid brittle hair, treat it with hydrating balms and masks.

Let It Work the Required Time

I hope the manufacturer’s instructions and my recommendations will help you keep tinting shampoo for the proper time. You can keep such a product on your tresses for up to 10 minutes maximum. Don’t forget to take into account your hair condition. Do not deviate from them and “commit a crime” of leaving in the purple shampoo for more than needed.
