Hair Styling & Chemical Treatments Flashcards

A 'balayage' technique differs from traditional foil highlights because:

Answer: Color is painted freehand onto the hair surface without foils

Balayage is a freehand painting technique applied directly to the hair surface, creating a soft, graduated, sun-kissed effect without foils.

When using a flat iron on hair that has been chemically relaxed, the stylist should:

Answer: Use lower heat settings to prevent cumulative heat damage

Chemically relaxed hair has already been structurally altered, making it more vulnerable to heat; lower temperatures reduce the risk of breakage.

Which of the following best describes 'oxidative' hair color?

Answer: Color that requires developer to develop and penetrate the cortex

Oxidative (permanent) color uses hydrogen peroxide developer to open the cuticle and oxidize dye precursors inside the cortex for lasting color change.

A client's relaxer service results in extreme shedding and limp, stretchy hair. This indicates:

Answer: Over-processing and loss of hair elasticity

Extreme elasticity loss and shedding are signs that the relaxer over-processed the hair, breaking down the internal protein structure.

The 'on-base' placement when setting a roller means:

Answer: The roller sits directly on its own base section

On-base placement means the roller sits centered on its own parting, producing maximum lift and volume at the root.

Thio-free permanent wave solutions typically use which active ingredient?

Answer: Cysteamine hydrochloride

Thio-free waves use cysteamine hydrochloride as the reducing agent, offering a gentler alternative to traditional ammonium thioglycolate.

When performing a chemical hair service on a client with a known scalp abrasion or open sore, the cosmetologist should:

Answer: Postpone the service until the scalp has healed

Open sores or abrasions on the scalp are contraindications for chemical services; performing the service risks chemical burns and infection.
