Hair growth occurs in cycles. During which phase does active hair shaft production take place?
Answer: Anagen
The anagen phase is the active growth phase of the hair cycle during which the hair matrix cells divide rapidly to produce the hair shaft.
Which structure forms the outer boundary of the hair follicle and is continuous with the epidermis?
Answer: Outer root sheath
The outer root sheath is a downward extension of the epidermis that surrounds the hair follicle from the skin surface to the follicle bulb.
The dermis receives its structural elasticity mainly from which protein?
Answer: Elastin
Elastin fibers in the dermis allow skin to stretch and recoil; loss of elastin with aging contributes to wrinkle formation.
A cosmetologist notices a client's nails have a yellow-brown discoloration with thickening. This could indicate dysfunction of which skin structure?
Answer: Nail matrix producing abnormal keratin
Abnormal nail matrix activity can produce irregular or discolored keratin, leading to thickened, discolored nails as seen in fungal infections or psoriasis.
The hair papilla, located at the base of the follicle, is important because it:
Answer: Contains blood vessels that nourish the hair matrix cells
The dermal papilla at the follicle base contains capillaries that supply nutrients and oxygen to the actively dividing matrix cells that produce hair.
Stratum granulosum cells contain lamellar granules that release lipids to form:
Answer: A waterproof lipid barrier between the granular and cornified layers
Lamellar granules release phospholipids, glycolipids, and ceramides between cells of the upper epidermal layers, creating a critical moisture barrier.
In cosmetology, understanding the Fitzpatrick skin type scale is important because it classifies skin based on its:
Answer: Response to UV radiation and tendency to tan or burn
The Fitzpatrick scale (Types I–VI) classifies skin by its phototype — how it responds to UV exposure in terms of burning and tanning — which guides treatment decisions.
