Describe the method of removal of superfluous hair by electrolysis.
A fine needle in a suitable handle is attached to the negative pole of a galvanic battery, introduced into the hair-follicle to the depth of the papilla, and the circuit completed by the patient touching the positive electrode; in several seconds slight blanching and frothing usually appear at the point of insertion; a few seconds later the current is broken by release of the positive electrode, and the needle is then withdrawn. Sometimes a wheal-like elevation arises, remains several minutes or hours, and then disappears; or occasionally, probably from secondary infection, it develops into a pustule.
A strength of current of a half to two milliamperes is usually sufficient; the time necessary for the destruction of the papilla varying from several to thirty seconds.
How are you to know if the papilla has been destroyed?
The hair will readily come out with but little, if any, traction.
What is the result if the current has been too strong or too long continued?
The follicle suppurates and a scar results.
Why should contiguous hairs not be operated upon at the same sitting?
In order that the chances of marked inflammatory action and scarring (always possibilities) may be reduced to a minimum.
In case of failure to destroy an individual papilla, should a second attempt be made at the same sitting?
