Q

How does permanent colour become lodged in the cortex?

A
  • The colour contains ammonia
  • It is the ammonia in the colour that will soften, open and swell the cuticle
  • This in turn will allow the colour to penetrate through the cuticle and enter the cortex
  • At this stage the colour molecules are small, once they enter the cortex they begin to swell
  • After full developmentt time the molecules are now 3 times their original size and therefore become trapped inside the cortex.
  • The hydrogen peroxide lightens the natural colour pigment so the newly introduced para colour molecules give the hair its new colour

Where on the head do you start colouring?

A
  • Always start at the most resistant area of the head

- Generally the nape unless grey hair is present

20
Q

% of grey resistant

A

Grey hair is the most resistant and therefore the colour needs to be applied to the greyest area first so the colour has longer on the airshaft to penetrate

21
Q

what is the Application of permanent colour?

A
  • Before colour Always skin test 24-28 hours
  • Where to start on the head
  • Always start in the most resistant area, the nape is more resistant if no grey hair is present
  • Depending on MI’s generally 20-25 minutes, then to refresh the midlengths to ends for 10-5 depending on the amount of adage (total processing of 30 minutes)
  • During application ensure there is no overlapping
  • Ensure an even application
  • Always consider the hairs porosity and condition, (strand test)
22
Q

Virgin hair

A
  • Read and follow MI’s. Always do a skin test and pre strand test
  • Apply colour from mid-lengths to ends then back to the roots, as the heat of the scalp would process the colour more quickly and would be brighter at the roots (target colour, ends would be dull not an even colour with the roots)
  • Processing - Depending on MI’S generally 10 minutes on mids to ends, then onto roots for 30 minutes. (total processing time of 40 minutes)
  • During application ensure you apply colour approximately 2cm away from the scalp with the first application.
  • Always consider the hairs porosity and condition
  • Strand test
