2. clients desired level and tone 3)are contributing pigments/ undertones exposed
3. what needs to be mixed together to get desired result

non-oxidative temporary no patch test required large colour molecule physical change attaches to cuticle last one shampoo no re growth

semi patch test required physical change last 4-6 weeks 2nd largest molecule penetrates cuticle no re growth

oxidative demi mix with developer patch test required deposit only physical change no regrowth

permanent mixed with developer patch test required new re growth lift and deposit in 1 step application chemical change

2. working with 1/4 to 1/2 inch sections apply colour to the mid shaft 1/2 to 1 inch from scalp up but not through the ends 3)when finished applying to mid shaft apply to roots and ends 4)process according to manufactures directions
3. lather and rinse
4. shampoo and condition

1. section hair into 4 sections
2. working with 1/8 inch sections apply lightener to mid shaft 1/2 inch to 1 inch from scalp up but not through the ends
3. place cotton strip at the scalp area along the part to prevent the lightener from touching the base of the hair 4)check application every 15 minutes or so double checking for even coverage and proper lifting 5)when the mid shaft has reached 1 level darker then the desired level remove cotton strip and apply lighter to roots and ends 6)process entire head until it has reached the desired level 7)rinse shampoo and gently condition 8)towel dry slect appropriate toner and apply toner in the same manner as a semi/demi application 9)process according to desired effect
4. rinse and condition

cuticle outer layer protects cortex overlapping layers transparent 20 of strength softens swells and raise the cuticle to allow penetration to cortex

cortex middle layer strength and elasticity melanin found here where chemical change takes place 80% strength colour molecules are added/natural melanin is changed

medulla innermost layer no known purpose sometimes absent occupies space round weightless cells colouring has no effect

diameter of indivitual hair strand course large diameter takes longer to process med average response to hair colour fine weaker product shorter processing time

the ability of hair to absorb moisture low stronger product and increase processing time average no problem high weaker product less processing time
