Two questions we get more than any other: will this colour actually show up on my dark hair? And then in the same breath — do I have to bleach?
Both fair, and both deserve a straight answer rather than vague reassurance. So here it is — by hair level, by shade, no hype.
First, an Analogy That Actually Explains It
Think about a dark piece of paper. If you try to draw on it with a regular marker, you can barely see it — the ink is there, but the dark base swallows most of it. To get colour to show up on dark paper, you either need a very vivid, heavily pigmented colour — or you need to switch to lighter paper first.
Your hair works exactly the same way. Semi-permanent dye deposits colour on top of your existing hair — it doesn't lift or remove your natural pigment. So the darker your hair, the more the dye has to compete with what's already there. Some shades will show up as a beautiful tint in sunlight. Others simply won't be visible. And some need a lighter base (lighter paper) to show up the way you're imagining.
This isn't a flaw in the dye — it's just physics. Knowing it upfront means you pick the right shade and set the right expectations, instead of spending money on something that disappoints.
What Works on Black Hair (Levels 1–3)
If your hair is naturally black or very dark brown with no visible warmth, you're working with a level 1–3 base. The shades that show up are the ones with the heaviest pigment — and even then, the result is a subtle tint that's visible in sunlight or under direct light, not indoors.
The shades that actually register on black hair:
- Riot — a deep red that shows as a dark ruby tint in sunlight. Indoors, your hair just looks like very rich black.
- Barbie — a dark red-pink tint that catches the light outdoors. More subtle than you'd expect from a shade called Barbie, but it's real.
- Gaia — a dark green tint in sunlight. Only really visible when light hits it directly. Indoors, it reads as very dark hair with depth.
These are genuinely beautiful results — multidimensional, not obviously artificial, the kind of thing people notice and ask about. But they're tints, not vivid colour. The inspo posts you've seen online are almost always on bleached hair. Managing that expectation now saves you disappointment later.
What Works on Dark Brown Hair (Levels 4–5)
Level 4–5 dark brown hair has enough variation in its natural pigment that a wider range of shades can land, and results are noticeably more visible than on black hair.
What actually works at this level:
- Hey Tiger — adds a warm, earthy brown hue that deepens your natural tone. Very wearable, very natural-looking — think expensive salon brown rather than obvious dye.
- Iris — gives dark brown hair a deep wine red-purple tint. Clearly visible in natural light, and one of the most underrated picks for this hair level.
- Ocean — a dark green tint that shows clearly on dark brown hair. Moody and more visible than you'd expect.
- Scarlett — a subtle red on dark brown hair. Visible in sunlight as a warm red-brown depth, but on the subtle end even at this level.
- Blackforest — on dark brown hair, it deepens your colour towards a very dark brown, almost black shade. The move if you want richer, darker hair rather than a visible colour change.
Here's How Every Shade Looks Across Hair Levels
Not sure where your hair sits, or what a shade will actually look like on you? This is our full colour chart — every shade, every level, no guesswork.
What Doesn't Work on Dark Hair (Needs Level 6+ to Show Up)
This is the section that saves you money. A lot of popular shades need at least a level 6 medium brown base to show up — on dark hair they'll be invisible or nothing like what you're picturing.
| Shade | Why it won't work on dark hair | Minimum level |
|---|---|---|
| Smoke | Ash grey tones need a light base — disappear entirely on dark hair | Level 6+ |
| Teddy | The milk tea/ash brown effect only reads on medium brown or lighter | Level 6+ |
| Bruise | Ash blue tone — vanishes on dark hair | Level 6+ |
| 12AM | Dark fashion blue — needs lighter hair to read as blue rather than black | Level 6+ |
| Any pastel shade | Pastels need near-white or platinum — they don't exist on dark hair | Level 9–10 |
We'd rather tell you this now than have you buy Teddy expecting a milk tea brown moment and end up with hair that looks exactly the same as before.
If You Want More — Here's the Honest Next Step
If your goal shade isn't on the dark hair list, you just need to swap to lighter paper first. A single round of Butter Bleach to level 6 medium brown opens up most of the range — you don't need to go anywhere near platinum.
If you want ash colours, pastels, or clearly visible fashion colour — bleach is the honest path. Not sure what's achievable at your level without bleaching? Check our No-Bleach Shade Guide for your exact match.
Making Your Colour Last
- Rinse with cool water — hot water opens the cuticle and pushes colour out faster
- Wash less often — every shampoo fades colour a little
- Use the Suck It Up Colour Locking Mask after dyeing and weekly after that — seals colour in, keeps hair conditioned
- Rinse immediately after swimming in chlorine
Colour on dark hair fades gracefully — the tones are close to your natural base, so there's no awkward grow-out or brassy fade. It just eases back to where it started.
