How to dye your hair black at home.

Set the scene.

24-48 hours before you plan to dye your hair, shampoo your hair TWICE to make sure all products and build up are free from your hair. As well as making sure the hair dye can really sink into your hair cuticle, it also gives you hair a chance to build up natural oils that will stop it from drying out.

Whatever dye you choose contains strong-smelling chemicals so make sure you apply it in a well ventilated room.

Set aside anywhere between 1-1.5 hours to colour your hair at home from start to finish.

Put on your hairdresser’s cape to protect your clothes, crack out your hair dye kit and your chosen box of black hair dye, cover any surface around you that might get dye on it and put newspapers on the floor.


Step one: Apply barrier cream.

Apply barrier cream to your hairline, ears and neck to make hair dye easier to rinse off when you’re done dyeing your hair.

Next, prepare the formula by mixing the colour and developer together as instructed. Pour the mixture into your hair dye bowl for easy application.

Make sure your hair is clean and dry, not wet or damp, before applying the dye.

Step two: Section your hair.

Use your comb to separate your hair into 4-8 sections, depending on how long and thick you hair is. Clip each section with using your clips to expose the roots and keep the sections away from each other so you can work on them one by one.

Step three: Apply the hair dye.

Apply the hair dye according to the instructions on the hair dye box and depending on the condition of your hair when you begin.

  • For previously dyed hair – work the dye into your roots first to avoid getting a different coloured band at your roots.
  • For hair that isn’t already dyed – work the dye into the whole of your hair, starting at the roots and painting down to the tips, making sure the hair is totally saturated. (You may find it easier to use two boxes and do away with sectioning your hair).

Step four: Let it develop.

While the colour is developing, you can put your hair in a shower cap to prevent it from touching and staining anything.

Leave the dye in for the amount of time specified on the box hair dye instructions. If you have particularly stubborn greys or different coloured roots to cover, you can leave the hair dye in 10 minutes longer to ensure it really takes.

If you feel any burning or itching – rinse it off straight away!

Step five: Rinse.

When the time is up, rinse your hair with warm water in the shower or over the sink. Keep rinsing until the water runs clear.

Don’t panic if you see a lot of colour rinsing out – it’s all part of the process!

Wash your hair twice with shampoo to remove all traces of the dye and then condition it really well.

Time to dry it!

Step six: Style and dry!

Use your hair heat protection spray all over your head to protect your colour before you use hot tools. Make sure you do this every time you dry your hair or use heated styling products from now on.

Dry and style your hair as usual, stand back and admire your colour!

Watch and learn. How the professionals do it.

How can I care for my black hair?
