Abstract
A hair nature measuring instrument comprises a hair catching portion, a rotational handle portion for rotating the hair catching portion, a rotation transmitting element having a restoring resilient force and interconnecting the hair catching portion and the rotational handle portion, and a grip portion for loosely circumscribing the rotation transmitting element. The nature of hair (hardness) is measured based on a correlation between the amount of rotation of the rotational handle portion and the amount of rotation of the hair catching portion when the hair catching portion already catching hair is rotated by the rotational handle portion.
