A client is experiencing significant hair loss, characterized by round or irregular patches on the scalp, with smooth, sometimes shiny skin in the affected areas. There are no signs of inflammation or scarring. What condition does the cosmetologist most likely observe?
- ATelogen Effluvium
- BAlopecia Areata
- CAndrogenetic Alopecia
- DTinea Capitis
Show answer & explanationAnswer & explanation
Correct answer: B. Alopecia Areata
Alopecia areata is an autoimmune condition resulting in sudden, often patchy hair loss, characterized by smooth, non-inflamed, sometimes shiny skin in the affected areas, without scarring.
Why the other options are wrong
- A. Telogen Effluvium is a generalized shedding of hair, often diffuse, not typically characterized by distinct round or irregular patches of complete baldness.
- C. Androgenetic Alopecia (male/female pattern baldness) is characterized by a gradual thinning of hair in specific patterns, not sudden, smooth, patchy loss.
- D. Tinea Capitis (ringworm of the scalp) is a fungal infection that causes scaly, itchy patches of hair loss, often with broken hairs, and may have inflammation, unlike the smooth patches described.
Alopecia Areata
An autoimmune disorder causing sudden, non-scarring hair loss, typically in round or irregular patches on the scalp or body, leaving smooth, sometimes shiny skin.
- Autoimmune condition
- Sudden, patchy hair loss
- Smooth, non-inflamed skin in affected areas
- Non-scarring
Memory trick: Areata is Areas of Absent Hair, Autoimmune Attack.
