Assembling a Hand-Held Trichotillometer and Determination of Epilation Force in Normal Individuals.

Aim: To assemble a simple, inexpensive hand-held trichotillometer and to determine the epilation force (EF) required to pluck the anagen hair and telogen hair from four regions of the scalp in healthy volunteers.

Materials And Methods: A simple hand-held trichotillometer was assembled by modifying a laboratory spring balance, and the instrument was calibrated after attachments. EF was measured in 30 healthy individuals on four regions of the scalp.
