Can I Use a Demi-Permanent Hair Color on Gray Hair?
By: Zara Kenyon
When it comes to gray 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 gray hair. This guide is here to help you figure out the ideal formula for every client...
What Does Demi-Permanent Color Do to Gray 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 gray hair in very different ways. While permanent colors like Koleston Perfect give your client up to 100% gray 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 gray 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 Color on Gray Hair?
Thinking about using a demi-permanent color for your client's gray root touch-up? By toning silver strands with Color Touch, you'll help them enjoy all of these benefits...
- Up to 30% gray 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 colors).
What are the Cons of Using a Demi-Permanent Color on Gray Hair?
There aren't any negatives when using a demi-permanent color on gray hair, but there are considerations for you and your client. The big one? Level of coverage. If your client wants that ‘every gray gone’ finish, a permanent color may be their better choice, as a formula like Koleston Perfect or Illumina Color is going to give them up to 100% gray coverage.
In this case, recommend they enjoy one of these permanent hair colors...
- Koleston Perfect is your pick for rich, intense colors 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 color. The reflective formula is luminous in every light, veiling strands in eye-catching shine while still delivering on gray coverage.
3 Tips for Using Demi-Permanent Hair Color on Gray Hair
1. Upgrade the Coverage with Color Touch Plus
Color Touch gives your client up to 30% gray coverage – just enough to create a seamless, natural-looking blend. But if they want a little more without upgrading to full gray coverage, Color Touch Plus strikes the perfect balance. The demi-permanent formula offers up to 70% gray coverage, thanks to a more concentrated dose of pigment that enhances the intensity of the color.
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 colored mids and ends untouched unless they truly need refreshing. This keeps the result dimensional and prevents color build-up over time.
3. Aim to Blend Rather Than Cover White Strands
Demi-permanent color works best when the goal is to diffuse grays, not complete disguise. So, instead of trying to mask every white strand, use your formula to soften and blend grays into the natural base. The result is a multi-tonal, more natural finish with softer regrowth – perfect for clients who prefer low-maintenance color.
How Long Does Demi-Permanent Hair Color Last on Gray 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 colors 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
Color-safe shampoo isn't just nice to have – it's essential for extending the wear of gray coverage. And, now, Wella Professionals has developed a formula that gives your client color 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 color 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 color an added layer of protection.
3. Enhance Shine With a Gloss-Boosting Mist
Your client is going to love their color even more with a veil of shine. It won't make their demi-permanent shade last longer on grays, but it will give their hair a lustrous look from root to tip. Choose a gloss-boosting spray specially formulated for colored hair to achieve the most luminous results. ULTIMATE COLOR Shine Spray is a hair colorist favorite, thanks to its weightless, irresistible sheen that leaves hair up to 4x smoother****.

** FOR PEOPLE NOT ALLERGIC TO HAIR COLORANTS
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 colorants, you should not color. ME+ is present in specific shades of Pure Naturals, Rich Naturals, Vibrant Reds, Special Blondes and Deep Browns of the Koleston Perfect brand.
