So Easy and So Soft!

I had never used semi-permanent dye before, but Mattie was unbelievably easy to apply. The color showed up instantly and my hair actually felt softer afterward. Even after 10 washes, it was still visible. Perfect for trying something new

Salon Results at Home

Mattie’s permanent line truly feels like salon quality. Full coverage, even on my gray strands, and the color stays rich and glossy. My hair feels healthy and not damaged at all. I’m sticking with this brand.

Shockingly Vibrant on Dark Hair

The pigments are insanely vibrant! I have dark brown hair and I expected it not to show, but the color came through beautifully. No damage, no harsh smell, just simple and stunning results

Emily

Long-Lasting, Rich Color

Amazing results! I achieved the same effect at home that I usually get at the salon. The color stayed vibrant for weeks and my hair felt strong and nourished. Easily one of the best permanent dyes I’ve used

Finally a Dye That Doesn’t Dry My Hair

This is the first semi-permanent dye that doesn’t dry out my hair. It left my hair shiny and smooth, and the fade was super even with no patchiness. Ideal if you love switching colors often

At-home colour, stylist-approved.

Mattie Semi-Permanent is a creamy, ready-to-use formula, so you can follow our step-by-step guide for an even, glossy result at home. If you’d rather not colour your hair yourself, simply take Mattie to your favourite hairdresser – the formula is salon-grade and easy for professionals to work with too.

THIS IS HOW EASY IT IS

1

Start with clean, dry or slightly damp hair.

Slip on gloves - colour goes on your hair, not your hands.

2

Apply generously from roots to ends (or only where you want colour).

Full saturation = the most even, polished result.

3

Let the colour develop for 20–30 minutes.

More time means deeper, richer intensity — you stay in control.

4

Rinse with lukewarm water until it runs almost clear.

No shampoo needed at this stage.

5

Mattie Semi-Permanent fades gradually over multiple washes, no harsh regrowth.

Support beyond the bottle

Mattie backs up its colour with clear education, realistic shade guidance and real people to talk to when you’re unsure. Whether you’re a stylist or colouring at home, you’re not left guessing about shades, timing or aftercare.

Colour that still feels like hair

Stylists like that Mattie gives intense colour without leaving hair feeling rough or hard to manage. Clients walk out with soft, touchable hair instead of that dry, over-processed feeling that puts people off colouring again.

Predictable, even results

Colour experts choose Mattie when they want bold shades that behave predictably on real hair. The creamy texture spreads easily, helping to avoid patchy spots and harsh lines so the finished colour looks smooth from roots to ends

QUESTIONS ABOUT SEMI-PERMANENT COLOUR?

Here are the most common questions about Mattie Semi-Permanent, answered clearly so there are no surprises – only great colour.

Will it show up on my hair — and do I need to bleach first?

It depends on your starting colour and the shade you choose.

On very light / pre-lightened hair: you’ll get the most vibrant, true-to-shade results especially for pastels and bright fashion colours.

On natural medium-brown hair or darker: results will be softer (more of a tint/reflect than a bold, opaque colour).

On dark brown or black hair: semi-permanent colour cannot lighten your hair you’ll mainly see a coloured sheen/shine (for example a red glow with Coral Red).

For pastel or very bright shades (like Soft Pink, Aqua, White Toner, Rose Gold or Denim Blue), we recommend very light blonde / pre-lightened hair for a true, vibrant result.

How long does it last — and how does it fade?

Mattie Semi-Permanent is designed to fade gradually with each wash, so there’s no harsh grow-out.

Based on our in-house wear tests:

On pre-lightened / bleached hair: colour can stay visible up to around 14 washes on average.

On natural medium-brown hair or darker: results may fade faster and look softer from the start.

What affects fading speed:

Very light/pastel shades fade quicker than deeper shades.

Frequent washing, very hot water, anti-dandruff shampoos, and strong clarifying shampoos fade colour faster.

Will it damage my hair? (What’s it free from?)

Mattie Semi-Permanent is a direct-dye cream with a mask-like texture. It sits mostly on the outside of the hair and is much gentler than permanent colour.

It is:

100% vegan & cruelty-free
Free from ammonia, peroxide, PPD & parabens
No developer required

Because it’s conditioning and non-oxidative, most people experience hair that feels softer, smoother and shinier after rinsing.

How do I use it step by step?

Prep: Wash once with shampoo (no 2-in-1). Skip conditioner before colouring. Towel-dry so hair is slightly damp.
Apply: Put on gloves and apply generously and evenly from roots to ends (or only on the areas you want to colour).
Process: Comb through for an even result and leave on for 20–30 minutes (within this range, longer usually means a more intense result).
Rinse: Rinse with lukewarm water until the water runs almost clear. Towel-dry gently and style as usual.

Always follow the instructions on the packaging and do an allergy test 48 hours before colouring.

Do I need a developer — or can I mix / dilute shades?
