3 Stylist-Approved Anti-Yellow Shampoo Products + How to Use Them Properly!

Anti-yellow shampoos — often called purple shampoos or toning shampoos — contain anti-yellowing agents that help slow down the rapid fading that happens after bleaching or colouring. This means your hair won’t lose shine as quickly or turn into that dull, lifeless grey! Anti-yellow shampoo’s main purpose is to maintain cool-toned shades after bleaching while keeping your hair glossy and preventing it from instantly becoming damaged-looking.

Here are 3 recommended anti-yellow shampoos, including their key formulas and the correct way to use them. And yes — there’s a surprise waiting for you at the end!

What Is Anti-Yellow Shampoo?

Anti-yellow shampoo works like a colour-correcting palette for your hair, cleverly neutralising yellow undertones to revive and brighten your colour. Many labels on the market — “toning shampoo”, “colour-correcting shampoo”, “purple shampoo” — are essentially products designed to target unwanted brassiness after bleaching.

Understanding How Anti-Yellow Shampoo Works

According to colour theory, purple is the complementary colour to yellow. When your hair becomes yellowish after bleaching, purple shampoo steps in to balance it out. The violet pigments lightly coat the surface of your hair strands, acting like a filter to cancel out yellow tones and restore a cooler shade — helping you avoid brassy gold or orange hues.

Some anti-yellow shampoos also help boost hair fullness and shine while correcting colour, making them especially ideal for grey, silver, ash, or any cool-toned hair colours.

The Functions & Benefits of Anti-Yellow Shampoo: How Purple Shampoo Helps Maintain Vibrant Hair Colour

1. Neutralises Yellow Tones to Improve Colour Results

The core purpose of anti-yellow shampoo is to counteract yellow or brassy orange tones that commonly appear after bleaching. By depositing violet pigments, your hair colour looks more like the cool shade you originally intended — such as ash, silver, or icy blonde — without unwanted colour discrepancies.

2. Cleanses While Reducing Brassiness

Besides colour correction, anti-yellow shampoo still functions as a cleanser, removing daily dirt and excess sebum. The added anti-yellowing agents help delay brassiness caused by UV light, heat damage, or mineral-rich water, preventing dullness.

3. Colour-Locking + Pigment Refreshing

To extend the longevity of dyed hair, many anti-yellow formulas combine colour-locking and pigment-depositing effects. Each wash adds a small amount of tone-refreshing pigment, maintaining brightness while slowing colour fade — helping you keep your ideal shade longer.

Why Does Hair Turn Yellow? The 4 Most Common Causes

1. Oxidation of Hair

Just like an apple browns when exposed to air, melanin in hair oxidises with UV exposure and pollution, leading to loss of shine and yellowish tones.

2. Colour Fading

Hair dye is like a beautiful coat for your hair — but over time, the pigment fades. Once artificial colour washes out, the natural yellow-based undertone reappears.

3. Water Quality

Hong Kong’s water contains higher mineral levels. These minerals cling to the hair surface, creating a dull cast that makes hair look more yellow.

4. Heat Damage

Heat tools are silent culprits. Frequent blow-drying or curling irons denature hair proteins and alter colour, similar to repeatedly heating food — damaging its original nutrients and appearance.

How to Use Anti-Yellow Shampoo Properly: 5 Key Steps!

Using purple shampoo (also known as toning shampoo or anti-yellow shampoo) is like following a recipe — technique matters if you want long-lasting, even-toned, smooth colour without dryness.

A. How Often to Use It

Use 1–2 times per week depending on how your colour changes. Overuse may cause dryness — just like over-cleansing your skin.

B. Step-by-Step Usage Guide

1. Wet Your Hair Thoroughly

Use warm water to soak the hair completely. This helps the shampoo foam evenly and improves pigment absorption.

2. Lather Before Applying

Create foam in your hands first instead of pouring concentrated liquid directly onto the scalp. Apply evenly, focusing on yellow-prone areas like the ends.

3. Massage & Leave On

Gently massage and leave on for 3–5 minutes (adjust according to product instructions). Longer time = stronger anti-yellow effect, but excessive time may cause a lavender tint.

4. Rinse Thoroughly

Rinse with plenty of water until no purple residue remains.

5. Follow With Conditioner

Because toning shampoos can be slightly drying, follow with conditioner or a hair mask to keep strands moisturised and smooth.

C. Important Reminders

1. Avoid eye contact.
2. Patch test before first use.
3. Do not leave on for too long — bleached hair absorbs pigment quickly.
4. Avoid staining around nails — wear gloves or lather before touching hair.
