Allergy,
infection, and vaccination induced hypertrichosis
Hypertrichosis can sometimes be promoted after chronic systemic
infections or as a result of vaccinations. The reason why infection
or vaccination should stimulate hair growth is unknown, but most
likely the immune system response to the prolonged antigen exposure
results in production of cytokines. Cytokines are chemicals that
the immune system uses to communicate between cells. Cytokines can
also affect non-immune system cells such as those in the hair follicles.
Cytokines that encourage immune system cells to proliferate may
also promote hair follicle cells in the same way.
Localized skin inflammation due to allergies or infection can also
promote hypertrichosis within the affected area.
