The hair follicle may be the root cause of the scab in the first place. Acne, as a result of an infected follicle, may appear to heal with a scab but the infected material may still be in-situ.
As you know, the hair itself is dead past the growing root.
So plucking the dead hair will do nothing, unless you are lucky enough to take all the infected material with it.
TIL all aromantic (aro) persons are misogynists (but not misandrists) by reading the comments.
