Can I Use a Demi-Permanent Hair Colour on Grey Hair?
By: Zara Kenyon
When it comes to grey coverage, you know a permanent hair color has got it... well, covered. But what about demi-permanent colors? If your client wants a lower-maintenance shade, they're a great option, too. Depending on the demi-permanent formula you use, you can achieve up to 70% coverage* of those silver strays, while enjoying the soft regrowth that comes with these gradually fading hair colors.
So, let's take a closer look at how demi-permanent hair colors can be used to cover grey hair. This guide is here to help you figure out the ideal formula for every client...
What Does Demi-Permanent Color Do to Grey Hair?
First, let's talk about the science. Unlike permanent hair colors, which penetrate deeply into the cortex of each strand, a demi-permanent color partially penetrates the hair shaft, depositing the color molecules just beneath the cuticle.
This means the two color products cover grey hair in very different ways. While permanent colors like Koleston Perfect give your client up to 100% grey coverage, demi-permanent formulas like Color Touch and Color Touch Plus give them up to 70% coverage*.
For this reason, we recommend Color Touch for clients who want natural-looking grey blending or a subtle root shadow, with soft regrowth lines proving easy to maintain. Demi-permanent colors also tend to be gentler on the hair, making a formula like Color Touch the perfect option for clients who are concerned about condition.
What are the Pros of Using a Demi-Permanent Colour on Grey Hair?
Thinking about using a demi-permanent colour for your client's grey root touch-up? By toning silver strands with Color Touch, you'll help them enjoy all of these benefits...
- Up to 30% grey coverage with Color Touch and up to 70% with Color Touch Plus.
- Softer regrowth lines, thanks to a formula that fades beautifully over 28 washes.
- True-to-tone vibrancy and shine.
- A wide array of shades available, including blondes, browns, vibrant reds, pastels and rainbow brights.
- Metal Purifier technology to neutralize shade-distorting metals in the hair.
- Reduced impact on the condition of the hair (compared to permanent hair colours).
What are the Cons of Using a Demi-Permanent Colour on Grey Hair?
There aren't any negatives when using a demi-permanent colour on grey hair, but there are considerations for you and your client. The big one? Level of coverage. If your client wants that ‘every grey gone’ finish, a permanent colour may be their better choice, as a formula like Koleston Perfect or Illumina Color is going to give them up to 100% grey coverage.
In this case, recommend they enjoy one of these permanent hair colours...
- Koleston Perfect is your pick for rich, intense colours that appear vibrant from root to tip. With ME+ technology to reduce allergy risk** and up to five levels of lift, it's one of the most versatile formulas on your salon shelf.
- Illumina Color delivers the most radiant, youthful, 100% natural-looking colour. The reflective formula is luminous in every light, veiling strands in eye-catching shine while still delivering on grey coverage.
3 Tips for Using Demi-Permanent Hair Colour on Grey Hair
1. Upgrade the Coverage with Color Touch Plus
Color Touch gives your client up to 30% grey coverage – just enough to create a seamless, natural-looking blend. But if they want a little more without upgrading to full grey coverage, Color Touch Plus strikes the perfect balance. The demi-permanent formula offers up to 70% grey coverage, thanks to a more concentrated dose of pigment that enhances the intensity of the colour.
2. Do Targeted Root Touch-Ups
To avoid over-toning or over-darkening the lengths, focus coverage strictly on the regrowth area. Fully saturate the roots for even blending, but leave previously coloured mids and ends untouched unless they truly need refreshing. This keeps the result dimensional and prevents colour build-up over time.
3. Aim to Blend Rather Than Cover White Strands
Demi-permanent colour works best when the goal is to diffuse greys, not complete disguise. So, instead of trying to mask every white strand, use your formula to soften and blend greys into the natural base. The result is a multi-tonal, more natural finish with softer regrowth – perfect for clients who prefer low-maintenance colour.
How Long Does Demi-Permanent Hair Colour Last on Grey Hair?
Every demi-permanent formula is different, but if it's Color Touch you're using, the rich, glossy formula will fade beautifully over 28 washes. This makes it one of the longest-lasting demi-permanent colours available.
To help your client get more mileage from their shade, recommend they follow this at-home hair care routine:
1. Wash With ULTIMATE COLOR Shampoo
Colour-safe shampoo isn't just nice to have – it's essential for extending the wear of grey coverage. And, now, Wella Professionals has developed a formula that gives your client colour vibrancy for up to 10 weeks***. ULTIMATE COLOR Shampoo is a mild yet effective, sulfate-free wash that's brimming with protective ingredients, including Metal Purifier; a technology that neutralizes shade-distorting metals in the hair. Suggest they massage it into the roots of their hair, then let the lather run through the lengths as they rinse. This subtle tweak in technique will keep their scalp fresh, while ensuring their hair enjoys a gentler cleanse.
2. Reduce Rinsing Steps With This Leave-In Mask
Washing is one of the biggest contributors to fading shades, so the less your client exposes their hair to water, the longer their colour is likely to last. That doesn't have to mean adjusting their washing schedule; they should follow a regimen that protects their tone while maintaining hair health. Instead, recommend swapping a traditional rinse-out treatment for a creamy leave-in mask.
We love ULTIMATE COLOR Miracle Leave-In Mask, which is packed with Glycine and Vitamin B5, plus moisturizing ingredients that leave hair with a healthy-looking sheen. Because it's a leave-in formula, your client reduces their rinsing steps every time they smooth it through damp mid-lengths and ends. Plus, it comes with a built-in UV shield that gives their demi-permanent colour an added layer of protection.
3. Enhance Shine With a Gloss-Boosting Mist
Your client is going to love their colour even more with a veil of shine. It won't make their demi-permanent shade last longer on greys, but it will give their hair a lustrous look from root to tip. Choose a gloss-boosting spray specially formulated for coloured hair to achieve the most luminous results. ULTIMATE COLOR Shine Spray is a hair colourist favorite, thanks to its weightless, irresistible sheen that leaves hair up to 4x smoother****.

** FOR PEOPLE NOT ALLERGIC TO HAIR COLOuRANTS
Although the risk of developing a new allergy is reduced, there remains a risk of allergic reaction that can be severe. Always ask your stylist to perform an Allergy Alert Test 48h before each colouration. Strictly follow safety instructions. If you have ever experienced an allergic reaction to hair colourants, you should not colour. ME+ is present in specific shades of Pure Naturals, Rich Naturals, Vibrant Reds, Special Blondes and Deep Browns of the Koleston Perfect brand.
