How do hair dyes work?

To understand, how hair dyes work – you first need to know about the hair anatomy.

Hair comprises of three layers – medulla, cortex, and cuticle.

The core layer is called the medulla.

Cortex is surrounded by a thick layer of cells. It is responsible for pigmentation and melanin.

The cuticle is the outer layer that protects your hair.

Along with hair anatomy, you also need to know three types of hair dye – temporary, semi-permanent, and permanent hair dye.

When you apply temporary hair dye, it will just stick to the outer layer of the hair, i.e. cuticle. Due to it, the colour will vanish instantly after shampooing.

Whereas semi-permanent hair dye contains molecules that can slip between the cuticle and can stick to the cortex. As a result, it won’t vanish easily even after shampooing. It will last for about 12 shampoos.

Permanent hair dye stays with your hair until it grows and falls out.

It contains two solutions alkaline and developers( Solution of hydrogen peroxide).

You mix both alkaline and developers together and apply them, right!

Here alkaline chemical opens up the cuticle and eases the hair dye to go to the hair cortex. Once it enters the cortex, the developer oxidizes the melanin molecule breaking melanin into a double carbon-carbon electron bond giving its own oxygen to fill the space.

As a result, melanin becomes colourless, releasing its sulfur atom.

Now, a reaction brings a new colour molecule by oxidizing dye precursors. Once, they get oxidized, they give new colour to your hair.

Here, dye couplers react with intermediates to form a polymer of pigment to prevent the colour from slipping back out. Due to this, you will have a permanent change in hair colour.

Why shouldn’t you dye your hair right after keratin treatment?

Keratin treatment adds protein to your hair to keep it healthy and shiny. While doing keratin treatment, it leaves some residue of keratin in your hair for some time because it takes time to penetrate deep inside.

Due to this, in addition to dye to your hair instantly, you will see the following problems.

Uneven colour

You dye your hair to get unique colour, right! Unfortunately, you won’t be able to get a unique colour if you dye it right after a keratin treatment. But you will see uneven patches of colour.

Frizzy hair

Your hair will be frizzy, if you dye your hair instantly. Due to it, keratin treatment will be worthless.

Flat hair

Your hair will be smooth on the fly. On top, it will flatten your hair. It won’t look good with flat hair.

keratin washout

While dyeing, you will need to wash out your hair. Doing so will dissipate protein as well.

Thus, I suggest that you wait for about 2 weeks for dyeing hair after keratin treatment.

The best way to dye hair before keratin treatment

I generally dye my hair first and do keratin treatment. Here is my generalized guide to dye your hair along with keratin treatment.

  • Initially, apply your favourite colour
  • Now wrap it in foil
  • Leave colour for about 30 minutes
  • Blow-dry your hair
  • Now wash your hair.
  • After washing your hair, apply the keratin treatment.
  • Again leave it for 40 minutes.
  • Again blow dry your hair.
  • Finally, straighten it &
  • Apply serum

You will have straight, colourful, and healthy hair afterwards.


Use sodium chloride-free and sulfate-free shampoo to wash your hair.


I often dye my hair first before treating it with keratin. But you can also dye your hair after doing keratin treatment. But dyeing it right after a keratin treatment is totally bad. It can give you frizzy hair. Thus, after doing keratin treatment, I suggest you to wait for two weeks for dyeing your hair.
