332A Scalp and Hair Analysis 4 — Questions and Answers
Question 1: What is the purpose of evaluating the hair's growth pattern during analysis?
- To determine the best colour formula
- To identify cowlicks, whorls, and directional growth that affect how hair falls and responds to cutting and styling (Correct answer)
- To calculate how fast the hair grows
- To determine the hair's porosity level
Correct answer: To identify cowlicks, whorls, and directional growth that affect how hair falls and responds to cutting and styling
Evaluating growth patterns identifies features like cowlicks, whorls, widow's peaks, and natural partings that influence how the hair falls, behaves, and responds to cutting and styling. Ignoring them can lead to poor results.
Question 2: What is telogen effluvium?
- A permanent form of hair loss
- A temporary condition where a large number of hairs prematurely enter the resting phase and shed (Correct answer)
- A scalp infection causing patchy loss
- An autoimmune disorder attacking follicles
Correct answer: A temporary condition where a large number of hairs prematurely enter the resting phase and shed
Telogen effluvium is a temporary hair loss condition triggered by stress, illness, surgery, hormonal changes, or nutritional deficiencies. A large number of follicles prematurely enter the telogen (resting) phase and shed simultaneously.
Question 3: What tool can be used to magnify the scalp and hair for closer examination?
- Tail comb
- Magnifying lamp or trichoscope (Correct answer)
- Blow dryer
- Flat iron
Correct answer: Magnifying lamp or trichoscope
A magnifying lamp or trichoscope (a specialized dermatological microscope) allows the stylist to closely examine the scalp and hair shaft for conditions, damage, or abnormalities that are not visible to the naked eye.
Question 4: What is the difference between a contagious and non-contagious scalp condition?
- All scalp conditions are contagious
- Contagious conditions can be transmitted to others and are contraindications; non-contagious conditions may allow service with modifications (Correct answer)
- Non-contagious conditions are always more severe
- There is no practical difference for the stylist
Correct answer: Contagious conditions can be transmitted to others and are contraindications; non-contagious conditions may allow service with modifications
Contagious conditions (like head lice, ringworm) can spread to others and are strict contraindications — no service should be performed. Non-contagious conditions (like psoriasis, seborrheic dermatitis) may allow service with appropriate modifications and care.
Question 5: What factors can contribute to dry scalp and hair?
- Excessive sebum production
- Over-washing, harsh products, low humidity, aging, and medical conditions (Correct answer)
- Frequent conditioning treatments
- Using only warm water for washing
Correct answer: Over-washing, harsh products, low humidity, aging, and medical conditions
Dry scalp and hair can result from frequent washing with harsh shampoos, environmental factors (low humidity, sun exposure), aging (reduced sebum production), certain medications, medical conditions, and overuse of heat styling tools.
Question 6: What is trichorrhexis nodosa?
- A scalp infection
- A hair shaft defect where nodes of swelling cause weak points that break easily (Correct answer)
- A type of alopecia
- An excess growth of hair
Correct answer: 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.
