The histologic changes induced by thermolysis of
hairs of the scalp and legs were studied by light microscopy.
Two techniques were compared on opposite sides: conventional thermolysis
(erroneously termed electrolysis) using bare needles and a newly
designed precision epilator using an insulated, bulbous-tipped
probe. Thermolysis generally did not immediately eliminate the
papilla and hair matrix. Thermal injury provoked an inflammatory
reaction which eventually destroyed the hair bulb. The insulated
probe produced greater damage to the peribulbar tissue below and
less necrosis of the perifollicular dermis above, enhancing the
likelihood of permanent epilation and reducing the probability
of scarring. The infundibulum and associated sebaceous glands
regenerated to near-normal architecture. The lower follicle was
replaced by a fibrotic streamer--a scar.
