In this guide, we’ll break down the differences between purple and blue shampoo, explain who should use each, show how to apply them for the best results, and share expert tips to keep your hair looking salon-fresh every day.

By the end, you’ll know which toning shampoo to reach for and how to get the most out of it.

Understanding the Color Theory Behind Purple vs Blue Shampoo

To understand purple vs blue shampoo, it helps to know a bit about the color wheel.

• Purple Shampoo contains violet pigments, which are the opposite of yellow on the color wheel. This means it cancels out yellow tones in blonde or silver hair.
• Blue Shampoo contains blue pigments, which neutralize orange and red tones, making it ideal for brunettes or dark blonde hair with warm undertones.

These shampoos deposit small amounts of pigment that counteract unwanted brassiness, helping your hair maintain a cooler, more neutral tone.

💡 Tip: Think of these shampoos as mini color-correcting treatments you can use at home to extend your salon results.

What Is Purple Shampoo & Who Should Use It?

Purple shampoo is a violet-toned shampoo that helps neutralize yellow, golden, or brassy tones in light hair.

Best for:

• Blondes – to keep hair looking bright and fresh.
• Highlighted hair – to prevent blonde highlights from turning brassy.
• Gray or silver hair – to maintain cool, shiny tones.

1. Wet hair well.
2. Apply purple shampoo evenly, focusing on brassy areas.
3. Leave for 2–5 minutes, depending on desired toning.
4. Rinse well.
5. Follow with conditioner.

💡 Tip: Use purple shampoo 1–2 times a week. Overuse can leave a slight violet tint. For more tips on toning, check Hair Toner Application.

What Is Blue Shampoo & Who Should Use It?

Blue shampoo is a blue-toned shampoo designed to neutralize orange or red tones in darker hair.

Best for:

• Brunettes – to remove unwanted warmth or orange tones, check out our article on Blue Shampoo for Brunettes.

• Color-treated hair – to maintain a cool, even tone.

How to use blue shampoo:

1. Wet hair thoroughly.
2. Massage into areas with brassy or orange tones.
3. Leave for 3–5 minutes.

5. Condition to restore moisture.

Can You Use Purple and Blue Shampoo at the Same Time?

Many users ask if they can mix purple and blue shampoos.

Yes, but cautiously:

• Only use on multi-tonal hair where you have both blonde and darker sections.
• Apply the appropriate shampoo to each section separately, rinse, and then condition.

Avoid mixing in one bottle: The pigments can neutralize each other, reducing effectiveness.

💡 Tip: If you’re unsure, schedule a consultation to prevent unexpected results and fix hot roots.

How to Use Purple or Blue Shampoo for Best Results

• Pre-wash hair with a gentle cleanser to remove buildup.
• Apply to damp hair, concentrating on brassy areas.
• Leave in for 2–5 minutes, depending on hair tone.
• Rinse well.
• Follow with a moisturizing conditioner or hair mask.

💡 Tip: Adjust frequency depending on hair type and brassiness level—fine hair may need less, thicker hair may need slightly more.

Before and After: What to Expect

• Purple shampoo: Brightens blonde, neutralizes yellow tones, enhances highlights.
• Blue shampoo: Removes orange or warm undertones from brunettes or dark blonde hair.
• Visual results vary depending on hair porosity, previous color, and frequency of use.

💡 Tip: For balayage or ombre, use the shampoo only on the lighter ends to avoid over-toning.
