As someone who cares about their hair, you’ve probably heard of purple shampoo. It’s a unique hair product that has become increasingly popular in recent years.
But do you know how to use it properly? Specifically, how long can you leave the purple shampoo in your hair? This guide will help answer that question and provide you with everything you need to know about purple shampoo.
WHAT IS PURPLE SHAMPOO AND HOW IT WORKS?
First of all, let’s discuss what purple shampoo is and how it works. Purple shampoo is a specially formulated shampoo designed for people with blonde, silver, or white hair. The purple color of the shampoo neutralizes yellow and brassy tones in the hair.
It does this by using the color wheel. Purple is opposite to yellow on the color wheel, so it cancels it out.
The ingredients in purple shampoo are what make it unique.
It contains purple pigments and toners, which work together to tone down yellow tones in the hair.
The pigments penetrate the hair shaft and neutralize the yellow pigments in the hair.
The result is a brighter, more vibrant blonde color.
Purple shampoo is not a permanent solution and it won’t change your hair color.
Instead, it neutralizes the unwanted tones in your hair to create a more even, balanced look. It’s a great way to extend the time between salon visits and keep your light-colored hair looking fresh.
HOW LONG CAN YOU LEAVE PURPLE SHAMPOO IN YOUR HAIR?
Now, on to the main question: how long can you leave the purple shampoo in your hair? The answer depends on a few factors, such as the color of your hair, the strength of the purple shampoo, and how often you use it.
If you have very light blonde or silver hair, you can leave the purple shampoo in your hair for at least 15-20 minutes.
If you have darker blonde hair, you can leave it in for up to 30 minutes. It’s important not to leave purple shampoo in your hair for too long, Some purple shampoos are stronger than others, so leaving them in for too long can have adverse effects on your hair.
So, the best solution is to do a strand test before and look at how much time it takes to bring the desired results and then apply it to all of your hair.
WHAT IS A STRAND TEST AND HOW IS THIS TEST PERFORMED?
A strand test is a test where a small section of hair is tested for its reaction to a hair product or chemical before applying it to the entire head. This is to ensure that the product doesn’t cause any negative reactions or damage to your hair.
To do a strand test, follow these steps:
- Take a small section of hair from the back of your head.
- Apply the purple shampoo to the section of hair.
- Wait for the time depending on your hair type and color that we already have discussed above.
- Rinse the section of hair thoroughly with water.
- Observe the color and condition of the hair to determine if it is safe to apply the purple shampoo to your entire head.
Note: If you use purple shampoo too often, it can also lead to purple or blue tones in your hair. It’s best to use it once a week or after every two weeks.
HOW TO USE PURPLE SHAMPOO?

Now that you know how long you can leave purple shampoo in your hair let’s look at how to use it properly.
- Wet your hair thoroughly in the shower or bath.
- Start by applying a decent amount of purple shampoo to your hair focusing on the areas with the most brassiness or start at the roots and working your way down to the ends.
- Wear a shower cap and leave the shampoo on for 30-60 minutes.
- Rinse your hair thoroughly.
- Follow up with a conditioner if your shampoo doesn’t contain conditioner in it. If it has conditioner mixed in it, then you can skip this step.
- Dry and style your hair as you do in routine.
ADDITIONAL TIPS ON THE USE OF PURPLE SHAMPOO
Here are some additional tips to help you get the most out of your purple shampoo:
- Wash your hair with a gentle, sulfate-free shampoo before using purple shampoo. This will help remove buildup in the hair and ensure that the purple shampoo can penetrate the hair shaft.
- If you have particularly dry or damaged hair, use a moisturizing hair mask or conditioner after using purple shampoo to restore moisture.
- Use purple shampoo once a week or once in 2 weeks for best results. Using it too often can dry out and damage your hair.
- Always use a conditioner after using purple shampoo. Purple shampoo can dry out the hair, so it’s important to moisturize the hair after use.
In general, it’s best to leave the purple shampoo in your hair for a minimum of 15-20 minutes and a maximum of 40-60 minutes at a time. If you leave it on too long, your hair may take on a purple hue that is difficult to remove.
However, if your hair is particularly yellow or brassy, you may be tempted to leave the shampoo on longer for an even better result. If you decide to leave the shampoo on longer, watch your hair closely and do a strand test before using the shampoo to make sure it doesn’t turn your hair purple.
