✍️ Sample 332A Questions & Answers

1. What is the purpose of a developer (hydrogen peroxide) in permanent hair colour?

✓ To open the cuticle and activate the oxidation process that develops colour

Developer (hydrogen peroxide) serves two purposes: it opens the cuticle to allow colour penetration into the cortex, and it activates the oxidation process that develops the colour molecules and lightens natural melanin.

2. What is trichorrhexis nodosa?

✓ A hair shaft defect where nodes of swelling cause weak points that break easily

Trichorrhexis nodosa is a hair shaft condition where weak points form as visible nodes or swellings along the strand. The hair breaks easily at these points. It can be caused by chemical damage, physical trauma, or genetic factors.

3. What does the 'level' system in hair colour refer to?

✓ The degree of lightness or darkness of a colour

The level system measures the degree of lightness or darkness of a hair colour on a scale from 1 (black, darkest) to 10 (lightest blonde). It is independent of the tone or hue of the colour.

4. A 180-degree elevation is also known as what?

✓ Long layers or increased layering

A 180-degree elevation involves over-directing the hair straight up from the head or directing lower sections upward. This creates long layers with shorter lengths at the top and progressively longer lengths at the bottom.

5. Which finishing product is most appropriate for adding shine and eliminating frizz on a completed style?

✓ Silicone-based serum or shine spray

Silicone-based serums and shine sprays coat the hair shaft, smoothing the cuticle and reflecting light to add gloss and control frizz.

6. What happens to the cuticle layer when hair is exposed to alkaline solutions?

✓ It swells and opens up

Alkaline solutions (pH above 7) cause the cuticle scales to swell, lift, and open. This allows chemicals to penetrate into the cortex but also makes hair more vulnerable to damage.
