PFE is a common response and can indicate that the follicle was effectively targeted.
Folliculitis typically develops after treatment and is not part of the immediate response.

Histamine reactions extend beyond the follicle pattern and are often associated with itching.
If a client reports worsening bumps, tenderness, or whiteheads after treatment, this is more consistent with folliculitis and should be evaluated accordingly.
