Can You Sleep With Purple Shampoo In Your Hair?

Even though purple shampoo is an excellent choice for blondes, they are not the only ones who can profit from it. Anyone with silver, pastel, white, gray, white, or platinum hair may also benefit from this hair care product in maintaining them.

It is helpful, but there comes a question: “Can you sleep with purple shampoo in your hair?”

This post will answer this question and provide you with helpful explanations, so check it now!

Can You Sleep With Purple Shampoo In Your Hair?

The answer to this question is no. According to hair experts, sleeping with purple shampoo in your hair overnight is not a wise idea. 

The first reason is that purple shampoo contains harsh ingredients that will leave the hair dull if left on for an extended time.

Moreover, purple shampoo comes with color molecules, and if left on the hair for long, too many color molecules will penetrate, causing the hair to turn a lilac hue or purple.

Therefore, leaving the purple shampoo on your hair overnight does not make it look healthier and has the potential to create dandruff.

What Happens If You Leave Purple Shampoo In Overnight?

If you keep the purple shampoo in your hair overnight, you may risk getting the wrong hair color that is not what you expected.

Many purple shampoos contain sulfates, propylene glycol, and tocopherol, all of which are known to cause scalp irritation and dryness.

To illustrate, sulfates which function as a cleanser if left in the hair for too long can cause irritation and dry scalp. Even worse, the burning feeling may occur if the scalp is sensitive.

What Should You Do To Your Hair If You Leave Purple Shampoo In It Overnight?

In case you have slept with purple shampoo in your hair, do not worry. You can quickly solve this problem by applying these two methods:

Use a clarifying shampoo on your hair

Clarifying shampoo is an excellent product since this type of shampoo is intended to eliminate build-up and deposits from your hair and can provide your hair a good look by reviving your hair’s brightness, smoothness, and manageability.

Apply moisturized treatments 

It is a necessary step you should do after it has been damaged by leaving the purple shampoo on for an extended period.

You can apply hair masks, deep conditioners, hair oils, and leave-in conditioners to condition and restore hair health.

How Long Should Purple Shampoo Be Left In Your Hair?

Purple shampoo is not like regular shampoo, so you should not use it as you do with your daily shampoo. Purple shampoo takes some time for the effects to be noticed. Thus, you must first give it time to rest and finish its task.

There will be instructions for how long to leave the purple shampoo on the hair, depending on the manufacturer and the product’s formula.

Also, the length of time you wait until rinsing is determined by your hair type, hair color, and if it has been color-treated.

Blonde hair

If your hair is naturally blonde, leave the purple shampoo on for around 2-3 minutes, and then rinse it off with cool water.

However, some manufacturers may suggest leaving the purple shampoo on for 5 minutes with this hair color, so read the directions on the label carefully.

Gray, silver, or platinum hair

Based on how frizzy or discolored your hair is, you can keep the purple shampoo on for up to 30 minutes if your hair is gray, silver, or platinum.

Colored or discolored hair

If your hair has previously been colored or discolored, leave the shampoo for 5-15 minutes before washing with cool water. 

If you are using purple shampoo for the first time, leave it on for 5-10 minutes and then rinse it off. If you observe little to no difference after drying your hair, you can go up to 15 minutes the next time.

Frequently Asked Questions (FAQs)

How Many Times Should Purple Shampoo Be Used?

The answer varies based on your hair condition and what you would like to accomplish.

In general, you should use the purple shampoo once or twice a week, or if you observe brassy undertones in your hair for the best results. When your hair is not being washed with purple shampoo, apply a non-tinted shampoo to keep it from becoming too light or retaining a violet color. 

However, for each specific hair type, the frequency of use may vary.

  • White hair: This hair color is tricky to achieve and more difficult to keep. To leave your hair white, you should use purple shampoo 1-2 times a week, substituting your regular shampoo and keeping it in for 5-7 minutes.
  • Platinum blonde or silver hair: You will use this shampoo 3 times a week on your hair, keeping it on for 5 minutes each time.
  • Light ash blonde: Bright yellow tones are found in light ash blonde hair, which has pigmentation and does not necessitate bleaching the hair to white. To maintain your ashy hair, utilize purple shampoo 3 times a week and keep it in for 3-5 minutes.
  • Light ash brown and dark ash blonde: To preserve the ash tone, utilize purple shampoo whenever you wash your hair instead of your regular shampoo. Also, keep it in for 3-5 minutes.

What if you do not see any significant changes? In case, after a month of use, the purple shampoo has not produced a change in your hair, you can raise your application to 2-3 times per week. 

Because everyone’s hair varies, it is important to observe the hair to see if there is any change to make adjustments as needed. You can also come to see your hairstylists or hair experts for further advice.

What Are Some Purple Shampoo Useful Tips?

Be patient

First and foremost, while using purple shampoo, patience is essential. Some may become discouraged when people do not notice instant results from using shampoo.

On the other hand, purple shampoo does not produce the same immediate results as hair dye. 

As a result, it is usual for multiple treatments to be required before you notice a significant improvement in your hair color.

Consider how your hair reacts or changes after using purple shampoo

After using purple shampoo, some people may see a slight lilac tinge. If this occurs to you, it is because you are using too much shampoo or keeping it on for too long. It is also possible that the shampoo formula is too harsh for your hair.

For the first case, purple shampoo is ideally used once a week or when you see ashy blonde tones in your hair to solve the problem of lilac-tinged hair.

To solve the other situation, in a 2:1 ratio, combine your purple shampoo with a normal one to dilute.

After that, you can use a sprayer to apply it. If you discover that the shampoo is still too powerful, dilute it with water before using it.

Deep condition

Purple shampoo may leave your hair shine and devoid of brassiness, but it can make your hair more porous due to its harsh formula.

Therefore, you had better deep condition your hair. Regardless of how frequently you use purple shampoo, you should still practice regular and appropriate hair care to keep your hair healthy and smooth.

Is It Possible For Purple Shampoo To Cause Hair Damage?

The answer is yes. If you apply purple shampoo too frequently, it can cause damage to your hair.

Purple shampoo, apart from regular shampoo, purple shampoo is a deterrent to brassy, undertoned hair, particularly blonde hair, since purple neutralizes yellow, as you can see in the color wheel.

As a result, using purple shampoo on a regular basis not only tends to turn your hair purple but also dries it out.

Should You Use Purple Shampoo On Your Hair If It Is Dry?

You can use purple shampoo on wet hair but not on dry hair. 

Even though dry hair may absorb more dye, it can not do that evenly. The hair strands of most people’s hair are drier and more porous than the rest. As a result, using purple shampoo on dry hair may lead to a patchy texture.
