A comedone is always inflamed while a pustule is not
A comedone occurs only on oily skin while pustules occur on all skin types
A comedone contains pus while a pustule is a clogged pore
A comedone is a clogged follicle (open or closed) while a pustule is an infected, pus-filled lesion (Correct answer)

Correct answer: A comedone is a clogged follicle (open or closed) while a pustule is an infected, pus-filled lesion

A comedone is a follicle blocked with sebum and dead cells (blackhead or whitehead), whereas a pustule is an inflamed, pus-filled papule caused by bacterial activity.

Question 78: A client's hair absorbs water and product very quickly but loses moisture just as fast. This characteristic indicates:

Low porosity
Zero porosity
Normal porosity
High porosity (Correct answer)

6.5–7.5
2.0–3.5
4.5–5.5 (Correct answer)
8.0–9.0
