Question 1

The dermal papilla of the hair follicle is BEST described as:

Accepted Answer

A vascularized connective tissue structure that nourishes the hair matrix

Answer

The dermal papilla is a vascularized connective tissue projection at the base of the follicle that delivers nutrients to the hair matrix cells.

Question 2

Which skin phototype according to the Fitzpatrick scale is associated with the HIGHEST risk of post-treatment hyperpigmentation in electrolysis?

Accepted Answer

Types V–VI

Answer

Darker skin types (Fitzpatrick V–VI) have more reactive melanocytes, making them more prone to post-inflammatory hyperpigmentation after electrolysis.

Question 3

The external root sheath of the hair follicle is a downward continuation of which skin layer?

Accepted Answer

Epidermis

Answer

The external root sheath is a direct downward extension of the epidermis that lines the outer wall of the hair follicle.

Question 4

Eccrine sweat glands are found in all of the following locations EXCEPT:

Accepted Answer

Lips

Answer

Eccrine glands are absent on the lips (and nail beds), whereas they are densely distributed on palms, soles, and axillae.

Question 5

During the catagen phase, the hair follicle:

Accepted Answer

Undergoes regression and shrinks

Answer

Catagen is a transitional regression phase lasting 2–3 weeks during which the follicle shrinks and cell division ceases.
