Your Ultimate Guide to Black Hair Dye

Pure jet black and raven-like shades, cool blue-black tones, or warm espresso hues. Black may be the darkest shade on the colour spectrum, but it still has plenty of range. Whether you’d suit a soft, muted tone or a deeply intense hue depends a lot on your natural features and personal style.

What black hair dye is best for my skin tone?

Let’s start with skin tone. The right black tones complement and enhance your complexion, giving it a healthy glow. The wrong ones make your skin appear dull, sallow or washed out.

Fortunately, there is a shade of black to suit every skin tone and undertone, and below is a quick breakdown of what will help you shine:

• Pale skin: A soft or off-black hair colour is gentler against pale skin, leading to a more natural result. However, if you’re going for a strong gothic effect, a blue-black or jet black tone, such as our Onyx shade, delivers a dramatic contrast.
• Medium skin: As the most flexible skin tone, almost everything works. Raven hair, soft black hues, smoky dark greys – these all sit nicely, allowing you to experiment based on your individual taste.
• Olive skin: With olive skin’s green/yellow undertones, a warmer black tends to harmonise best. Think a black-brown espresso effect.
• Dark skin: Jet black, blue-black and purple-black shades, including our own Black Amethyst, look especially rich and luminous against darker skin tones.
• Warm undertones: Lean into off-black, espresso or blacks with undertones of brown or red – these echo the gold and peach in your skin rather than fight it.
• Cool undertones: Blue-black, jet black and true black colours are your best friends. The coolness in the dye reflects the pink/blue undertones in your complexion.

These are our recommendations, but they’re not strict rules. Skin colour is a broad spectrum, and numerous black shades combine well with different complexions. Try out different tones, and you’ll find the black that helps your skin glow like it was born to.

What black hair dye works with my natural colour?

Your natural hair colour also plays a role in choosing your perfect shade of black. While black is the most dominant pigment, able to overwhelm practically any other colour, there will be subtle differences depending on the base it’s applied to.

For the most true-to-tone results, we suggest using a hair lightening kit before application. However, this may not be necessary depending on your existing shade.

Dyeing blonde hair black

A pale blonde base (Level 9-10) is typically the best starting point to achieve authentic black hair that meets your expectations.

Dyeing copper hair black

Due to their natural red-orange pigments, black shades usually take well on copper and ginger hair, with warm underlying pigments often adding extra richness and dimension.

Warm and natural, true blacks look particularly gorgeous when applied directly to copper hair, such as espresso, off-black and soft black.

Dyeing brown hair black

Brown hair already has the depth and pigment to support black, so practically any shade can work on light or medium-brown hair. Jet black, blue-black, dark cherry, black olive – these all take well and fade gracefully.

However, do keep in mind that very dark brown hair may conflict with the black dye, resulting in an espresso or another brown-black shade. If this isn’t what you’re after, pre-lightening to a lighter brown base could help achieve a more desirable outcome.

At Directions, our semi-permanent black hair dyes are also designed to help enhance and intensify existing black hair, so you can enjoy richer, bolder locks while still looking natural all year round.

Once you’ve found your new favourite black based on your skin tone, natural colour and personal style, it’s time to put it to work. 

Here’s our quick guide to dyeing hair black at home, so you can guarantee clean, stylish and sophisticated results:

1. First, make sure you do a strand test and skin patch test. The strand test shows you exactly how deep and rich the black will land on your hair, while the patch test rules out allergic reactions.
2. Wash your hair with Pre-Colour Shampoo to strip away product, oils and buildup. This balances your hair’s pH so it can soak up your chosen shade of black.
3. Apply a thin layer of Vaseline, baby oil or petroleum jelly along your hairline and around your ears, pull on your gloves, and drape yourself in dark towels or a salon cape.
4. Move your black from its pot into a mixing bowl. This gives you better control, easier application and a much cleaner result.
5. Part your hair into sections and work the colour through with a tint brush, starting at the roots. Cover every strand evenly – patchy coverage shows up fast on dark shades.
6. Once every strand is coated, leave the colour to develop for 15-30 minutes, or follow the timing suggested by your strand test.
7. Rinse under cool or lukewarm water, away from your eyes, and keep going until the water runs completely clear.
8. Towel-dry, style, and head out cloaked in your gorgeous new black!

How do I lighten black hair dye?

If you’re looking for a lighter, softer shade of black, blend your chosen colour with a hair toner or conditioner in a mixing bowl. All Directions semi-permanent colours are fully mixable, so you are free to create your own unique shades.

How do I get black hair dye off skin?

Black hair dye is often trickier to remove from skin due to its depth and intensity. We advise using Vaseline, baby oil or petroleum jelly along your hairline and ears to protect against stains, and wearing dark towels or a salon cape to cover any bare skin.

If black dye does get on your skin, wipe it with a damp cloth or cotton pad as soon as possible. For more stubborn stains, try micellar water or a gentle facial cleanser. Massage this gently into the stain, then rinse it away with warm water.

How do I get black hair dye out of clothes or carpet?

Got black dye on your clothes? Rinse it under cold running water, starting from the back to help lift it from the fabric. Apply a liquid detergent or stain remover, allowing it to sit for a few minutes, and then put your clothes in the washing machine.

For stains on your carpet, upholstery or furniture, start by gently blotting them with a clean cloth. Next, dab it with a mix of warm water and a small amount of either washing-up liquid or white vinegar. Don’t rub it too hard – this can make the stain worse.

How long should I leave black hair dye in?

We suggest leaving black hair colour for 15-30 minutes after application, as this gives time for the dye to develop and absorb into your hair. However, every person’s hair is different, so use the results of your strand test to determine how long you should wait.

Can I use black hair dye when pregnant?

If you are pregnant or breastfeeding, we recommend speaking with your healthcare professional before colouring your hair. As with any cosmetic product, always follow the instructions and complete a patch test before use.

Black hair dye typically lasts longer than other colours due to its depth and strong pigment. But if you want to get the absolute most out of your shade, these tips on maintaining black hair dye are a must:

• Start with Pre Colour Shampoo before you colour – it balances your hair's pH so it's perfectly prepped to absorb every bit of your chosen black.
• Keep your washes down to 2-3 times a week – the less you wash, the longer your black hair stays deep and glossy.
• Stick to cool or lukewarm water when washing – hot water lifts the cuticle and lets colour escape, while cooler temperatures seal everything in.
• Switch to a Colour Protecting Shampoo and Conditioner – they're formulated to fight off the fade, all while keeping your hair soft, sleek and glossy.
• Ease off the heat styling – straighteners, curlers and hot dryers speed up the fading process and rob your hair of its signature shine.
• Protect your hair from the elements – hours in strong sun, chlorinated pools and salty seawater can all dull your black and pull it toward a tired, brassy grey.

How long does black hair dye last?

Our black hair colours don’t have a specific longevity, as this depends on several factors:

• How deep your shade of black is
• How thick and porous your hair is

Our tips above will help you extend your black’s brilliance for as long as possible, while regular top-ups can revive your colour when the fade sets in.

Does black hair dye damage hair?

At Directions, our semi-permanent black shades are designed with your hair's health in mind. Every pot is packed with nourishing, deep-conditioning ingredients that hydrate while they colour, so your hair stays healthy, soft and glossy rather than dry and brittle.

Permanent black dyes use stronger colour-developing ingredients, such as peroxides and ammonia, to create longer-lasting results, which can be more demanding on the hair. Semi-permanent colours offer a gentler alternative without the same commitment.

As the darkest shade on the colour spectrum, you may assume that black doesn’t play well with others. But that’s not exactly true. While too much black will overwhelm anything else, a little bit can go a long way to add depth and richness to other colours, or give your base black a different dimension.

Our fully mixable semi-permanent colours allow you to experiment to your heart’s content, but here are our top picks for mixing black hair dye:

• Black & blue hair dye: When mixed with black, blue deepens the tone and delivers a cool, glossy blue sheen, which intensifies the overall darkness of your hair.
• Black & purple hair dye: This produces a rich plum or aubergine-black, just like our Black Amethyst shade with its purple undertones. Purple also counteracts any yellow or brassiness in your hair, keeping your black cool and clean.
• Black & red hair dye: Red adds warmth and dimension, creating mahogany or black cherry tones that glow subtly red when the light catches your hair just right.
• Black & brown hair dye: Small amounts warm the black toward an espresso or off-black with a sunlit quality, rather than a stark jet black.

We suggest starting with a little black colour and working up from there. Black is the most dominant pigment, so too much of this will leave no room for other colours to have an impact.

When mixing colours at home, remember:

• Use a mixing bowl and tint brushes to combine colours
• Measure your ratios carefully to get the best outcome
• Perform a strand test to try out your custom shade
• Mix a maximum of 2-3 colours at once

What hair colours go well with black hair dye?

While mixing colours with black is a delicate balancing act, it’s far less of an issue when it comes to split-dyes or similar patterns. Black is a brilliant pair for practically any bright shade, as its depth helps other colours pop with even more intensity.

The options are truly limitless, but here are some of our favourite combos:

• Black & red hair dye: An instant classic – black and red has been a beloved combo for generations, delivering graphic, high-contrast looks with a bit of edge.
• Black & purple hair dye: Rich and slightly gothic, the depth of purple sits beautifully next to black without the contrast feeling harsh.
• Black & pink hair dye: The brightness of a hot pink against a dark black is equal parts playful and loud – great for those who live to make a statement.
• Black & yellow hair dye: Another popular pairing, black allows a partnering yellow to glow brighter and bolder than it can on its own.
• Black & white hair dye: Pure white or silver beside black brings a classic monochrome contrast – bold, modern and endlessly photogenic.
• Black & orange hair dye: Warm and fiery against black, orange is less stark than red but still vivid, and often has a bold autumnal feel.

Ready to move on from your black hair? Black can be a stubborn shade to shift, but it's far from impossible – here are a few ways to help fade and remove black hair dye faster:

• Wash your hair more often under hot water – the heat opens your hair cuticles, so colour bleeds out quicker
• Wash with a deep conditioner – leaving this on for just 10-20 minutes before you rinse can help lift black dye from your hair
• Speak to a professional colourist – they can advise on the best and safest route to remove your black hair colour

Avoid using bleach or colour strippers unless advised by a professional, as they can dry out your hair and cause uneven results.

What colour does black hair dye fade into?

How your black hair colour fades depends on your chosen shade and your natural hair colour.

The most common fade is the black becomes a muted blue, slate or dirty grey colour before returning to your base – especially with blue-black or cool blacks.

However, blacks can fade into murky greens, brassy reds, warm browns or faded charcoal depending on the colour’s unique undertones.
