What does the first number before the line mean?
Depth
What does the first number after the line represent?
Major tone
What does the second number after the line represent?
Minor tone
What is meant by the term ‘prelevelling’?
Evening out porosity of hair by adding more tones
What is meant by the term ‘pre pigging’?
Adding tones back into the hair prior to a colour service
What volume of peroxide would you use with a quasi and toner colour?
10 vol
What does 20 vol peroxide do?
Lift by one shade, covers 100 % white hair
What does 30 vol peroxide do??
2-3 shade lift
What volume of peroixde would you use with high lift tint, bleach or use on dark hair?
40 vol
How do you work out the ratio to dilute water into peroxide?
1) Strength needed-strength stock
2) first part answer of number=water required
3) first part number of strength/volume required=peroxide amount
What would you use powdered perxoide for?
Highlights, adding lot of light to hair, with quasi
What would you use creame peroxide with?
Bleach
How many shades lift does high lift tint give?
2-4
what do permenant and quasi colours contain?
oxident
how does permenant colour work?
By the oxident and ammonia dissolving into the natural colour pigment

ECO Cortex
What does an porosity test test for?
PCU Cuticle

Red, yellow, blue
what colours are secondary?
Orange, violet, greeen
What are opposite colours that neutralise?

1 wash
How long does a semi permenant last and what does it do?
6-8 wahes, gives no lift, simply tones and adds depth
How long does a quasi last and what does it do?
up to 24 washes, mix with semi-permanant, no lift, adds depth and tones, covers 50 % white hair
How long does a permenant last and what does it do?

What are highlights and low lights used for?
Create lighter/ darker tones
What size molecules are temp colour on the hair saft?
Large attach cuticle
What size molecules are semi permenant colour on the hair saft?
small molecules, attach cuticle and layers inbetween
What size molecules are quasi colour on the hair saft?
diffrent sized molecules, enter cortex , oxidise starts
What size molecules are permenant colour on the hair saft?
small molecules that expand when oxidisied so they become so big that they cant fit through the cuticle so they are trapped in the cortex
What affect does permenant, bleach and high lift tint have on the hair structure?
open cuticle
What PH Level is permenant?
7.5-9.5 alkaline
What PH Level is Bleach?
8-9.7 alklaine
What PH Level is semi-permenant?
6.8 acidic
What PH Level is quasi-permenant?
6.8-9.0 alkaline
