Question

question 47 of 100
which part of the hair shaft plays an important role during chemical services?
select the correct response:
hair bulb
hair follicle
medulla
hair cuticle

Explanation:

The hair cuticle is the outermost layer of the hair shaft. During chemical services like coloring or perming, chemical products must penetrate or interact with the cuticle to alter the hair's structure or color. The hair bulb and follicle are part of the hair's root structure under the skin, not the shaft, and the medulla is the innermost, less functionally relevant layer for chemical services.

Answer:

hair cuticle
