Hydrogen peroxide strength will be determined if the lift of depth is required or deposit of tone, if coloring white or sensitized hair.

Low volume strength/ percentage for when yiu are depositing tone and darkening the hair.

Higher volume/percentage when lifting colour and lightening the hair.

Q

How can the room temperature affect the service

A

Temperature can slow down or accelerate the process

In hit temperatures colour should be applied quickly and evenly, starting with the most resistant areas and development monitored continually. In cold temperatures additional heat may be used to accelerate the development process.

Prelighten hair is degree of lift cannot be achieved.

Q

name the different types of melanin in the hair

A

Eumelanin (granular, bigger, dark brown, determines depth)
Pheomelanin (smaller, diffused, through cortex, pale yellow, reddish or ash in colour, determines tone and makes yellow and red hair)

22
Q

How do semi-permanent colour work on the hair?

what is its PH?

A

A mixture of colour molecules enter the cortex and lie on the outer edge of the cortex, these are gradually removed by shampooing.

has a PH value of 6.8

23
Q

How do quasi permanent colours work on the hair?

what is its PH?

A

Ammonia opens the cuticle for colour to enter. Different sized molecules enter the cortex and are oxidised by the oxygen from the hydrogen peroxide. Smaller molecules are gradually lost each time the hair is shampooed.

has a PH value of 7.5-9.5

24
Q

What effect does temperature have on the application of the product?

A

On virgin hair to ensue an even result, the colour should be applied to the middle lengths first then the ends and finally the roots. On virgin hair, if the correct application process is not followed, heat from the scalp would cause the colour to look brighter or lighter at the roots.

25
Q

How does temperature affect the Development of colouring and lightening process?

A

Heat will radiate from the scalp and will make the colour or lightening product develop more quickly and this will affect the method of application

A very warm salon will make the colour or lightening product develop more quickly. A cold salon will slow down the development of the colour

Added heat will make the colour or lightening product develop more quickly

26
Q

Why would you pre soften the hair?

A

To lift the cuticle when the hair is resistant to colour

Allow the colour to penetrate more efficiently

27
Q

What is the method of pre softening the hair?

A

Low volume hydrogen peroxide is applied in neat sections to dry hair. The hair is then dried with the hydrogen peroxide on the hair. Now the chosen colour can be applied

28
Q

What is the method for pre pigmenting

A

Apply warm shade of pigment from any type of hair colour at

Depending on the product used for pre pigmentation, it will determine if the product needs to be removed prior to the application of the target colour.
