Ultimate Guide to Maintaining Blonde and Grey Hair with Purple Shampoo

Caring for blonde, grey, or color-treated hair relies on your home care routine. We consistently recommend using purple shampoo as a key product.

While it’s commonly associated with blonde hair, purple shampoo is also highly effective for grey, silver, and cool-toned coloured hair, helping to keep your colour looking fresh, vibrant, and free from brassiness.

What Is Purple Shampoo and Why Is It Important?

Purple shampoo is a specially formulated product containing violet pigments designed to neutralise unwanted yellow and brassy tones in light-coloured hair. Think of it as colour correction for your hair just as purple concealer cancels out yellow in makeup, purple shampoo counteracts warm tones in your hair.

Even though Singapore's water is clean, it still contains trace minerals that can gradually affect your hair’s tone. Exposure to the sun, humidity, and heat can also accelerate colour fading. Without using purple shampoo, cool-toned hair colours like ash blonde or silver can quickly become dull or yellowish.

That’s why, even in our tropical climate, purple shampoo plays a crucial role in preserving the clarity and brightness of lighter hair tones.

Who Should Use Purple Shampoo?

Purple shampoo isn’t just for blondes. It’s highly recommended for:

• Blonde hair – natural or bleached

• Grey or silver hair – to keep the tone clean and crisp

• Ash brown or cool-toned colours – to maintain the cool undertones

• Colour-treated hair – particularly when lightened or highlighted

If your hair tends to turn warm or brassy over time, purple shampoo can help maintain a cooler, fresher tone in between colour appointments.

How Often Should You Use It?

At Kudos by Headlines, we suggest using purple shampoo one to three times per week, depending on your hair type and how quickly brassiness develops.

Here’s a simple guide:

• Start with once a week if your tone remains stable.

• Increase to two or three times per week if yellow tones appear.

• Leave it on for at least three minutes (up to five for stronger results) before rinsing thoroughly.

The key is to allow enough time for the violet pigment to settle into the hair, cancelling out any yellow hues. Don’t just apply and rinse immediately patience is what makes purple shampoo effective.

Can Purple Shampoo Cause Scalp Irritation?

Some people experience itchiness or dryness after using purple shampoo. This often relates to the product’s pH level. The natural pH of the scalp and hair typically sits between 4.5 and 5.5, which helps keep the cuticle sealed and the scalp healthy. In contrast, purple shampoos tend to have a pH of around 9, making them significantly more alkaline.

This higher pH causes the hair cuticle to open slightly, allowing the violet pigment to deposit more effectively. However, it may also leave the scalp feeling sensitive or dry.

If you notice irritation:

• Alternate with a gentle, plant-based shampoo on non-purple-shampoo days

• Follow with a hydrating conditioner or hair mask

• Use a scalp-soothing serum or treatment as needed

• Reduce usage to once a week if symptoms persist

Your stylist at Kudos by Headlines can also recommend a purple shampoo suited to sensitive scalps.

Additional Tips for Brighter, Longer-Lasting Colour

• Avoid overuse. Too much purple shampoo can leave an unwanted violet cast or overly ashy tone.

• Wash with cool or lukewarm water, which helps keep the hair cuticle closed and colour locked in.

• Always pair with a nourishing conditioner or treatment to restore softness and moisture.
