Uniform layers are commonly cut by holding the hair at 90 degrees from the head form, producing similar lengths throughout.
Haircutting · medium07Which bond is broken by water or heat and reforms as hair dries or cools?+
Correct answer: Hydrogen bond
Hydrogen bonds are weak physical side bonds. Water and heat break them temporarily, which is why wet sets and thermal styling can reshape hair.

Correct answer: elasticity
Elasticity is the hair’s ability to stretch and return without breaking. Poor elasticity signals damage and affects chemical-service decisions.
Hair structure · easy09Which condition is a reason to avoid a scalp service and refer the client?+
Correct answer: An open lesion
An open lesion may indicate injury or infection. Do not perform a service that could worsen it or expose others; refer the client when appropriate.

Correct answer: condition and texture
Fine, lightened, porous, or damaged hair requires less heat. Always test the temperature before applying the iron to the hair.

Nail care · medium13A nail showing signs of a contagious fungal infection should be+

Correct answer: inflamed or infected areas
Massage can aggravate inflammation or spread infection. Identify contraindications during consultation and skin analysis.
Skin care · easy15Soft wax is normally removed+

Soft wax requires a removal strip. It is applied with hair growth and removed quickly against hair growth while supporting the skin.
Hair removal · medium16Which color neutralizes unwanted orange in haircolor?+
Correct answer: Blue
Blue sits opposite orange on the color wheel, so a blue-based tone is used to neutralize excess orange.

Correct answer: a frayed cord
A frayed cord creates shock and fire risks. Disconnect the tool and do not use it until it is properly repaired or replaced.
