Describe the key factors you need to consider when analyzing a client's hair and skin tone before formulating a hair color.

Undertones, existing hair color, skin tone, eye color, hair condition, lifestyle, and desired outcome.

Explain the difference between temporary, semi-permanent, demi-permanent, and permanent hair color, and how their chemical compositions affect the hair.

Temporary color coats the hair shaft; semi-permanent penetrates slightly; demi-permanent blends and adds tone; permanent alters the hair structure. Chemical compositions vary in developer strength and dye molecule size.

A client with naturally dark brown hair wants to achieve a level 7 ash blonde. Outline the steps you would take, including product selection (developer volume, toner, etc.) and precautions.

Assess hair health, perform strand test, lighten with appropriate developer volume (20-30 vol), tone with ash blonde toner, condition hair. Precautions: Monitor processing, avoid over-processing, protect scalp.

How do you determine the appropriate developer volume to use when lifting hair color, and what are the risks of using too high or too low of a volume?

Developer volume depends on the desired lift and hair condition. Too high can cause damage; too low may not achieve the desired result.

Explain the purpose of using a toner after bleaching hair, and describe different types of toners and their effects on the final hair color.

Toner neutralizes unwanted undertones (yellow, orange) after bleaching. Different toners deposit different pigments to achieve the desired final shade (ash, gold, etc.).
