How to Remove Demi-Permanent Hair Colour
Your client loved their demi-permanent hair colour, but now they're ready for a change. And, while these low-commitment shades are designed to fade over time, some clients want a faster refresh. The good news? In most cases, you don't need to strip the colour completely. From tonal correction to colour reducers, there are several ways to create a clean canvas for their next look.
So, here's your complete guide to removing (or 'resetting') demi-permanent shades, so your client's hair is ready for their next shade…
What is Demi-Permanent Hair Colour?
Demi-permanent hair colour deposits pigment without significantly lightening the hair. Unlike permanent colour, it contains no ammonia or uses a low-alkaline formula, helping to enhance, refresh or tone existing colour. The result is glossy, natural-looking colour that gradually fades over time rather than growing out with a noticeable demarcation line.
Demi-Permanent vs. Permanent vs. Semi-Permanent Hair Colour: What's the Difference?
Demi-Permanent | Permanent | Semi-Permane | |
How it works | Deposits colour on the surface and in the first layers of the hair shaft | Uses an alkaline agent and developer to lift and deposit colour inside the hair cuticle | Deposits colour onto the hair's surface only |
Lightening ability | Minimal to no lift | Can lighten and darken hair | No lift |
Longevity | Up to 28 washes | Long-lasting until hair grows out or is recoloured | Typically 4-12 washes |
Fade pattern | Gradually fades true-to-tone | Grows out with visible regrowth | Fades quickly with washing |
Best for | Toning, glossing, refreshing colour and blending first greys | Full colour transformations, grey coverage and permanent results | Fashion shades, colour experimentation and temporary tonal changes |
Hair impact | Gentle, low-commitment colour service | More permanent change to the hair structure | The most temporary colour option |
Maintenance level | Low to moderate | Moderate to high | Low |
Ideal client | Someone who wants rich, glossy colour without a long-term commitment | Someone looking for maximum longevity or significant colour change | Someone who wants to try a new shade with minimal commitment |
Does Demi-Permanent Hair Colour Wash Out Completely?
Demi-permanent hair colours are designed to gradually fade from wash to wash. Case in point: Color Touch fades beautifully over 28 washes, giving your client true-to-tone wear from one salon visit to the next. In most cases, demi-permanent dyes will eventually wash out completely. However, highly porous hair can retain pigment for longer, particularly if it has been previously lightened or chemically treated. As a result, some clients may notice lingering tones that take longer to fade than expected.
Why Does Demi-Permanent Hair Colour Sometimes 'Stick'?
Is your client's colour visible long after the time it would usually take to fade? Here's why a demi-permanent formula might stick around for longer:
- High porosity hair – If your client's hair is highly porous (meaning it has gaps along the cuticle), demi-permanent hair dye molecules can settle into the lower layers and become tricky to remove.
- Pre-lightened base – Lightening hair can contribute to porosity, letting demi-permanent colours penetrate deeper. The lighter base also enables these pigments to appear more visible.
- Overlapping pigments – We love clients who diligently book in their touch-ups to keep their colour fresh. However, demi-permanent pigments can sometimes accumulate with repeat applications, causing them to fade more slowly.
How to Remove Demi-Permanent Hair Colour
1. Try Correcting the Colour First
It's rare that a demi-permanent colour actually needs to be removed. In most cases, you can give your client a fresh shade by building on the colour that's already there. So, if they're saying they want their current shade switched, your goal may be less about removal and more about rebalancing. Clients who say they want a colour removed usually mean they want to get back to the shade they were before. You can do this by:
- Neutralizing rather than stripping – Instead of trying to remove all the pigment, cancel out unwanted tones of yellow with violet, orange with blue, and red with green/ash tones in their formula.
- Layering strategically with demi-permanent colour – A fresh application of a demi-permanent hair colour can refine or redirect the tone without needing a full correction service.
- Refreshing with a gloss service – In many cases, a transparent or sheer tonal shift (courtesy of a SHINEFINITY gloss) is enough to visually 'reset' the result.
2. Trust the Process – and Use Clarifying Shampoo
Demi-permanent hair colours are called 'low-commitment' because they fade over time, so if your client is willing to wait, letting the shade run its course is often the gentlest approach. If they wish, they can speed things along with a clarifying shampoo. These deep cleansers are armed with potent surfactants, which can accelerate the fading process and encourage residual pigment to wash away more quickly.
For clients trusting the process, remind them it can take a few weeks, depending on how fresh their colour is. Color Touch, for example, fades beautifully over 28 washes.
3. Apply a Color Reducer in the Salon
If your client's color can't be corrected or the unwanted tones won't budge, consider using a color reducer to rinse out the lingering pigment. Color Renew is your in-salon solution, with a gentle, zero-damage blend of Vitamin C and Citric Acid. It respects the hair's natural melanin and structure, while creating a clean canvas for a fresh coat of color.
Here's how to apply it:
1. Mix one 9g sachet of Color Renew Crystal Powder with 90g of Activator Liquid or water in a bowl/applicator bottle.
2. Apply from roots to mid-lengths and ends. If there's build-up in certain areas, start with these sections first.
3. Develop for 5–45 minutes, depending on the depth of color and the level of reduction required.
4. Remove the formula in the appropriate way:
- If you're re-coloring hair, rinse with water only and dry thoroughly first.
- If you're lightening the hair, cleanse thoroughly with shampoo first.
So, When Should Demi-Permanent Hair Colour Be Removed?
Most demi-permanent colours can be corrected, rebalanced or allowed to gradually fade, and we recommend trying these approaches first to streamline your client's colour service. But if the colour is stubborn, lingering in patches, or not fading in the expected time period, reach for a hair colour remover or reducer. This will 'reset' the base, so hair is ready for a fresh coat of colour.
