Fitzpatrick Type I describes very fair skin that always burns and never tans, requiring extra caution with energy-based treatments.
Hypertrichosis differs from hirsutism in that hypertrichosis refers to:

Hypertrichosis is generalized excess hair growth not driven by androgens, while hirsutism is androgen-dependent excess hair in women.
The catagen phase of the hair cycle is best described as:
Answer: A transitional regression phase
Catagen is a brief transitional phase lasting 2–3 weeks during which the follicle regresses and mitotic activity ceases.
Which hormone is most responsible for converting vellus hairs to terminal hairs in androgen-sensitive areas?
Answer: Dihydrotestosterone (DHT)
Dihydrotestosterone (DHT) is the primary androgen that stimulates conversion of vellus to terminal hairs in androgen-sensitive follicles.
Post-inflammatory hyperpigmentation (PIH) following electrolysis is most likely in clients with which Fitzpatrick skin types?
Answer: Types IV, V, and VI
Clients with Fitzpatrick Types IV–VI have higher melanin density and are more prone to PIH after thermal or chemical skin injury.
The arrector pili muscle connects the follicle to the:
Answer: Papillary dermis
The arrector pili muscle runs from the follicle to the papillary dermis and contracts to cause 'goosebumps.'
