Purple shampoo is great. But it can also go wrong.

Especially if you’re overusing it.

Your hair type, current color, and desired outcome will determine the frequency of using purple shampoo.

Some people see results using it once a week, other people need to use it 2 (or maybe even 3) times a week.

Understanding Purple Shampoo

Before diving into the frequency of using purple shampoo, we’ll explain a bit about purple shampoo.

If you already know what purple shampoo does, and how it works, skip this section.

What It Does

Have you ever noticed your blonde hair turning a little yellow or brassy? That’s where purple shampoo comes in handy.

This shampoo neutralizes those unwanted yellow tones and brightens your hair, helping it look more vibrant and fresh.

By using purple shampoo, you’ll maintain the cool, ashy tones you desire, making your hair look like you just left the salon.

How It Works

The magic behind purple shampoo lies in its color.

The purple pigment in the shampoo directly counteracts yellow and brassy tones in your hair. This is because purple is opposite yellow on the color wheel, so the two colors cancel each other out.

When you apply purple shampoo, you’re depositing small amounts of purple pigment onto your hair which helps counteract the brassiness.

How Often Should You Use Purple Shampoo?

It’s generally recommended to use purple shampoo once or twice a week. If you have lighter hair, or less brassy hair, you can mix it with regular shampoo. If you have brassier hair, you can use it as is.

Dry hairPurple pigments can be drying, causing hair to lose moisture and shine.Brassy tones become more noticeable, making hair appear dull and lifeless.If hair is already dry or prone to damage, reduce frequency of use or alternate with nourishing sulfate-free shampoo.
Undesired purple tintOverusing purple shampoo may result in a subtle purple hue.Yellow or brassy tones become more noticeable.Use purple shampoo once or twice a week according to your hair type and color; don’t leave it in for prolonged periods of time.
Altered toneHair color can turn lavender if overused.Yellow or brassy tones become more noticeable.Start by underusing instead of overusing; adjust frequency based on needs of your hair and avoid leaving shampoo in too long.

What Happens If You Use Purple Shampoo Too Often?

If you use purple shampoo too often, you might encounter a few issues.

One of the most common problems is experiencing dry hair. The pigments in purple shampoo can be drying for your hair, causing it to lose its natural moisture and shine.

Overusing purple shampoo may also result in a subtle purple tint on your hair, which might not be the desired outcome.

What Happens If You Use Purple Shampoo Too Little?

On the other hand, if you use purple shampoo too infrequently, you may not see the desired effects.

Purple shampoo helps neutralize yellow or brassy tones in blonde and light-colored hair.

If you’re using it too little, those tones can become more noticeable, making your hair appear dull and lifeless.

Can You Use Purple Shampoo Every Day?

It’s generally not recommended to use purple shampoo every day.

According to hair care brand Redken, you should use purple shampoo at most once or twice per week. Using it daily might lead to the issues discussed above, such as dry hair or an unwanted purple hue.

Remember that the frequency of using purple shampoo ultimately depends on:

  • Hair type
  • Color
  • Highlights
  • Brassiness

It’s essential to find the right balance that works for your hair. You might need to experiment a bit before discovering the perfect frequency for your unique needs.

Keep an eye on your hair’s health and appearance as you figure out how to use purple shampoo for your hair.

Determining Your Purple Shampoo Frequency

To find the perfect frequency for you, you may have to experiment a little. Always start underusing instead of overusing:

  • Start underusing instead of overusing purple shampoo
  • Assess your hair color first
  • If blonde, silver or gray, purple shampoo helps tone down yellow hues
  • For light or color-treated hair, purple shampoo may be beneficial in maintaining desired shade
  • Frequency depends on intensity of hair color and how quickly it develops brassy tones
  • Use 1 to 2 times a week for maintenance or more often for maximum tonal deposit
  • Hair’s overall condition is crucial in determining frequency of using purple shampoo
  • Purple shampoos can be drying, pay attention to hair’s hydration levels
  • Consider using less frequently or alternating with a nourishing, sulfate-free shampoo if hair is already dry or prone to damage
  • Don’t leave purple shampoo in your hair for a prolonged period as it may cause dryness and alter the tone too much

Assessing Hair Color

When it comes to using purple shampoo, it’s essential to assess your hair color first. If your hair is blonde, silver, or gray, purple shampoo helps tone down the yellow hues, giving your hair a cool, icy aesthetic.

For those with light hair or color-treated hair, purple shampoo may also be beneficial in maintaining the desired shade.

Depending on the intensity of your hair color and how quickly it tends to develop brassy tones, the frequency changes.

You might want to use purple shampoo 1 to 2 times a week for maintenance or more often for maximum tonal deposit.

Evaluating Hair Condition

Another crucial factor in determining the frequency of using purple shampoo is your hair’s overall condition.

Bear in mind that purple shampoos can be drying, so it’s essential to pay attention to your hair’s hydration levels. If your hair is already dry or prone to damage, consider using purple shampoo less frequently or alternating with a nourishing, sulfate-free shampoo.

Additionally, don’t leave purple shampoo in your hair for a prolonged period, as it may cause dryness and even alter the tone too much.

Purple Shampoo Frequency & Hair Color

When using purple shampoo, it’s essential to consider your hair color and specific needs.

Below, we’ll break down the best frequency for different hair colors to help you achieve your desired look.

It’s better to start slower and increase your frequency, than starting out overusing it.

Grey hairOnce or twice a week, adjust frequency as neededMaintains brightness and prevents yellow/brassy tones
Blonde hairOnce a week, increase to twice a week if brassy tones appearMaintains cool blonde tones
Light brown hair with highlightsOnce a week, adjust frequency as needed, can be combined with regular shampooNeutralizes orange or brassy hues in highlights

Platinum Hair

For platinum hair, use purple shampoo once or twice a week and mix it with your regular shampoo. It will help maintain your stunning, icy hue and prevent unwanted yellow tones.

Make sure not to overuse it, as it might lead to a lavender tint in your hair.

Gray Hair

Gray hair can benefit from purple shampoo as well; using it once or twice a week ensures that your gray locks stay bright and free from any yellow or brassy tones.

Remember to adjust the frequency based on the needs of your hair, as each person’s hair reacts differently.

Blonde Hair

For blonde hair, try using purple shampoo once a week to maintain your cool blonde tones. If you notice your hair turning brassy, you can increase your usage to twice a week.

Be cautious not to leave the shampoo on too long or overuse it, as this could result in an undesired purple tint.

You can also combine it with your regular shampoo for a more subtle treatment on your blonde hair.

Light Brown Hair

For those with light brown hair and highlights, using purple shampoo once a week can help neutralize any orange or brassy hues.

It won’t have the same dramatic impact as it does on blonde or gray hair but will still offer benefits.

Feel free to adjust the frequency to your hair’s needs or combine it with your regular shampoo for a gentler treatment.

Creating a Purple Shampoo Routine

Application Tips

If you feel like your hair needs a little pick-me-up in between full treatments, you can mix a small amount of purple shampoo with your regular shampoo while showering.

Here’s how to apply it right:

  • Begin by wetting your hair thoroughly, then apply the purple shampoo evenly throughout.
  • Massage the shampoo into your hair until you’ve worked up a good lather.
  • Leave the shampoo in for about 3-5 minutes before rinsing it out completely.

This timing is important because it allows the shampoo to do its job without over-toning your hair.

Maintaining Hair Health

Purple shampoo helps keep your hair vibrant and cool-toned, but alternate its use with a nourishing and moisturizing shampoo.

Do this at least one or two times a week to maintain your hair’s overall health.

While using purple shampoo, pay close attention to how your hair feels. If it becomes dry or brittle, reduce the frequency of use to prevent further damage.

Additionally, consider using a deep conditioning treatment or hair mask once a week to offer your hair extra hydration and protection.

Remember that a proper purple shampoo routine will make your hair look more vibrant and cool-toned, taking care of your hair’s health is equally important.

Alternatives and Complementary Products

Blue Shampoo

If you have brunette hair with highlights or lightened sections, blue shampoo can be a great option for you. This shampoo works to neutralize orange and brassy tones to keep your locks looking fresh and vibrant.

Just like purple shampoo, you don’t need to use blue shampoo every day. Instead, apply it once a week or every other week, depending on your hair’s needs.

Make sure to follow the instructions on the bottle and avoid overusing, as it can cause your hair to adopt a blueish tint.

Color-Protecting Conditioner

To maintain your hair color’s vibrancy and longevity, using a color-protecting conditioner is key.

These conditioners are formulated to provide an extra layer of protection against color fading, as well as keeping your hair hydrated and manageable.

Apply it every time you wash your hair and leave it in for a few minutes before rinsing.

Remember that using hair care products designed for color-treated hair can make a significant difference in your hair’s overall health and appearance. So, when choosing your shampoo and conditioner, always opt for color-safe options that will work best for your hair type and color.

Frequently Asked Questions

How often should you use purple shampoo for balayage hair?

It’s recommended to use purple shampoo once or twice a week for the best results. Some people may find it beneficial to mix a small amount of purple shampoo with their regular shampoo for a less intense treatment. Keep in mind that every individual’s hair is unique, and you should pay attention to your own hair’s needs.

When can you use purple shampoo after dying your hair?

After dying your hair, it’s important to wait a few days before using purple shampoo.

After that period, you can start incorporating purple shampoo into your hair care routine.
