Paul Mitchell Hair Gloss Treatments: The Demi Professional Toners

A quick honest note before you scroll. "Hair gloss" gets used to mean two different things, and it's worth knowing which one you're shopping for. Some products called gloss are conditioning treatments that add a hint of pigment and a lot of shine (closer to a tinted mask). Paul Mitchell's hair gloss range is the other kind: The Demi Color Gloss, a professional ammonia-free demi-permanent toner that needs mixing with developer, a 48-hour skin test, and ideally a trained pair of hands.

This is the same product colourists use in-salon to glaze your hair after a balayage, kill brass after a lightening service, or refresh your shade between full appointments. The results are seriously good. The application just isn't as plug-and-play as a mask. If you're a colourist, a confident DIY-er, or you're shopping for someone who is, you're in the right place. Every shade we stock at Revive in Codsall is genuine Paul Mitchell, sourced through authorised UK distribution.

The 6 Shades and What Each One Does

  • Pearl Ash: The icy-blonde colourist's secret weapon. A cool, pearly toner that knocks yellow out of pre-lightened blondes and leaves an expensive, light-reflecting finish. Probably the most-requested shade in this range.
  • Ash: A cooler, more neutral toner for taking warmth out of mid-blonde to light brown hair. Great for anyone with naturally warm hair who wants to dial down the brass without going full platinum.
  • Violet: A purple-based toner for neutralising yellow on blondes. Stronger pigment than purple shampoo, more controlled than a mask, and more durable than either.
  • Blue Violet: Cooler than Violet, designed to neutralise both yellow and orange tones. Ideal for blondes who lift brassy on the mid-lengths after lightening.
  • Red: Refreshes red and copper hair between professional colour services, restoring the vibrancy that tends to fade fastest of any tone.
  • Natural: A clear, naturally toned base that can be used on its own to add shine and condition without changing your colour, or mixed with the other shades to dilute their intensity.

How to Use The Demi Color Gloss

The Demi is mixed 1:1 with Paul Mitchell Cream Developer, usually at 5 Vol (1.5%) for pure toning and shine, or 10 Vol (3%) when you need a touch of lift and longer-lasting deposit. It's brushed through clean, towel-dry hair and processed for around 20 minutes at room temperature. Always do a 48-hour skin test before each application, even if you've used the product before, and a strand test if you're unsure of the result on your specific hair.

Pick up the right developer from our peroxide and developer collection, and read our skin test and strand test guide before mixing anything. If you'd rather skip the developer and skin test entirely, our Paul Mitchell Colour Depositing Treatments are the at-home-friendly alternative; same brand, no developer, no mixing.

Paul Mitchell Hair Gloss FAQs

Is The Demi Color Gloss the same as a conditioning hair gloss?

No. Paul Mitchell The Demi is a true ammonia-free demi-permanent hair colour designed to be mixed with developer. Conditioning glosses (sometimes called hair glazes) are pigmented masks you can use straight from the tube. Both add shine and freshen tone, but The Demi gives a longer-lasting, more pigmented result and needs more care to apply.

Do I need to do a skin test?

Yes, always. A patch test 48 hours before every application is non-negotiable for any demi-permanent colour, even if you've used the product before. Allergic reactions can develop suddenly, and the only way to catch one safely is a fresh patch test each time. Our full skin test guide walks you through it.

What developer do I need with The Demi Color Gloss?

Paul Mitchell Cream Developer in either 5 Vol (1.5%) or 10 Vol (3%). Use 5 Vol for pure toning, refreshing colour, or adding shine without lift. Use 10 Vol if you need a small amount of lift (around half a level) and slightly longer-lasting deposit. Mix one part colour to one part developer.

How long does The Demi last?

Typically 4 to 6 weeks, fading gradually rather than leaving a regrowth line. Demi-permanents wash out over time, which is part of why colourists like them: they don't build up on the ends like a permanent would.

Can The Demi cover grey hair?

It blends grey rather than covering it solidly. Expect a softening and toning effect rather than full opaque coverage. For solid grey coverage, a permanent colour is more appropriate.

Is The Demi suitable for DIY use?

It can be used at home if you're experienced with mixing professional colour, comfortable with developer, and willing to do a skin test. If any of that gives you pause, our Colour Depositing Treatments give similar refresh results without developer, mixing or skin tests, and are designed for at-home use.

Is The Demi vegan or sulphate-free?

The Demi range is vegan and free from ammonia. Paul Mitchell as a brand is also cruelty-free. Check the individual product page for the full ingredient list if you have specific sensitivities.
