  1. A client has polycystic ovary syndrome (PCOS). Which mechanism MOST directly explains her increased facial hair?

    Answer: Elevated androgens converting vellus to terminal follicles

    PCOS causes elevated androgens (testosterone/DHT) that bind androgen receptors in facial follicles, converting fine vellus hairs to coarse terminal hairs.

  2. The region of the hair follicle that contains pluripotent stem cells critical for follicle regeneration is the:

    Answer: Bulge region

    The bulge region of the outer root sheath harbors follicle stem cells that can regenerate the lower follicle with each new anagen cycle.

  3. Dehydration of the skin affects electrolysis outcomes because desiccated tissue has:

    Answer: Lower electrical conductivity requiring higher current intensity

    Dehydrated skin has reduced water content, lowering its electrical conductivity and potentially requiring current adjustments to achieve effective follicle destruction.

  4. Which cranial nerve provides motor innervation to the muscles of facial expression that may contract during electrolysis on the face?

    Answer: Facial nerve (CN VII)

    The facial nerve (CN VII) innervates all muscles of facial expression, which can involuntarily contract in response to electrolysis stimulation.

  5. The process by which a hair follicle transitions from producing terminal hair back to producing vellus hair (as in male-pattern baldness) is called:

    Answer: Miniaturization

    Follicular miniaturization is the progressive shrinking of terminal follicles under DHT influence, producing progressively finer, shorter hairs until the follicle becomes dormant.

  6. Apocrine sweat glands differ from eccrine glands in that apocrine glands:

    Answer: Are activated at puberty and are odor-associated

    Apocrine glands become active at puberty, open into hair follicles in axillae and groin, and produce a protein-rich secretion that bacteria metabolize to produce body odor.

  7. When performing electrolysis on the bikini area, a client's follicles are MOST likely oriented at what angle relative to the skin surface?

    Answer: 30–45 degrees

    Bikini area follicles typically angle at approximately 30–45 degrees, requiring probe insertion at a matching angle for accurate follicle alignment.
