NO PRIOR KNOWLEDGE OF HAIR COLOUR

Hair colour training usually begins within the second year of an apprenticeship once the trainee has a
basic knowledge of hairdressing and working in a salon environment.

By the same token if it is your intention to become a hair colour specialist only, without ever learning
or
performing any other hairdressing services and have signed up for this course to that end then their are
a few things you should know before you begin. (Please read “Understanding White Light, Colour and
Hair colour” before proceeding further.)

The most important rule in hair colour is:

“Always take a skin test 48 hours before carrying out any hair colour procedure.”

We all look at hair colour as fun. To change someones natural base colour from dark brown to white

blonde is an exciting prospect. The movies and media advertising give the impression this is a simple
process “Just apply the bleach straight from the pack to the head and Wow! The hair is now white
blonde.” Nothing could be further from the truth. If you did in fact try this you would achieve three
colours; Pale blonde on the roots where the hair is still soft and only six weeks old. Yellow on the
middle lengths where the hair is six weeks to three months old and starting to harden. Dark Orange on
the ends where the hair is over three months old. (Please read “Keratinisation” to learn how hair ageing
effects hair colouring before proceeding further.)

In simple terms; How does hair colour work.

Colour is seen by the human eye when individual Visible electronic waves in White light (Daylight) hit
corresponding pigments and are reflected. Please see the spectrum of visible light waves below.
