Question 1: What is traction alopecia?
- Hair loss caused by hormonal changes
- Hair loss caused by repeated pulling or tension on the hair from tight hairstyles (Correct answer)
- Hair loss from a fungal infection
- Natural hair thinning due to aging
Correct answer: Hair loss caused by repeated pulling or tension on the hair from tight hairstyles
Traction alopecia is hair loss caused by chronic tension or pulling on the hair follicles from tight hairstyles such as braids, ponytails, weaves, or extensions. If caught early, it can be reversed by reducing tension.
Question 2: What is pediculosis capitis?
- A bacterial scalp infection
- An infestation of head lice (Correct answer)
- A fungal infection of the scalp
- Excessive dryness of the scalp
Correct answer: An infestation of head lice
Pediculosis capitis is an infestation of head lice (Pediculus humanus capitis). It is highly contagious and is a strict contraindication for salon services. The client should be referred for treatment before any service is performed.
Question 3: What is psoriasis and how does it present on the scalp?
- A contagious bacterial infection with pus-filled bumps
- A chronic autoimmune condition causing thick, silvery-white scales over red, inflamed patches (Correct answer)
- A temporary allergic reaction to hair products
- A fungal infection causing hair loss
Correct answer: A chronic autoimmune condition causing thick, silvery-white scales over red, inflamed patches
Psoriasis is a chronic, non-contagious autoimmune condition that causes rapid skin cell turnover. On the scalp, it presents as thick, silvery-white scales over red, inflamed patches. It can extend beyond the hairline.
Question 4: What is the elasticity test used to determine?
- How shiny the hair is
- The strength and condition of the cortex and its internal bonds (Correct answer)
- The percentage of grey hair
- The natural curl pattern
Correct answer: The strength and condition of the cortex and its internal bonds
The elasticity test evaluates the internal strength of the cortex by stretching a wet strand of hair. Healthy hair can stretch up to 50% of its length and return. Poor elasticity indicates damaged bonds and weakened structure.
Question 5: Which scalp condition is contagious and requires immediate referral rather than salon service?
- Dandruff
- Psoriasis
- Ringworm (tinea capitis) (Correct answer)
- Seborrheic dermatitis
Correct answer: Ringworm (tinea capitis)
Ringworm (tinea capitis) is a contagious fungal infection that is a strict contraindication for salon services. The client must be referred to a healthcare professional for treatment. Performing services could spread the infection.
Question 6: What does hair texture analysis involve?
- Measuring the length of the hair
- Evaluating the diameter of individual hair strands to classify them as fine, medium, or coarse (Correct answer)
- Counting the number of grey hairs
- Checking the hair's colour level
Correct answer: Evaluating the diameter of individual hair strands to classify them as fine, medium, or coarse
Hair texture analysis involves examining the diameter of individual hair strands, typically by holding a single strand between the fingers. Hair is classified as fine (small diameter), medium (average), or coarse (large diameter).
