Hope to get pastel hair?

If you hope to get pastel hair, you must have an already even blonde hair colour.

You should colour the base colour of your hair to a shade lighter. (bleach)

Mixing ratio: 1 unit of hair dye + 2 units of volume developer

Apply the colour on the whole length of your hair and leave it on for 15 mins.

If you want to end up with a nice even colour, work the colouring cream through your hair every 5 min.
