Abstract (en)

An expandable curler (1) by which the hair winding no longer requires a particular skill, because the strain imparted by the curler to the hairs no longer depends on the strain applied by the operator throughout the winding operation, and wherein possible differences in strain caused by the humidity or by the drying are compensated by the curler, which consequently expands or contracts itself, comprises a curler body split in two or more rigid longitudinal sectors (2, 3) forming together a winding surface (4, 5) receiving an amount of wound hairs in a contracted configuration; locking means (9, 10) of said sectors (2, 3) in said contracted configuration; and elastic means (8), housed inside said sectors (2, 3), apt to apply on said sectors (2, 3) a predetermined elastic force expanding the winding surface 4, 5) and determining a strain state at the wound hairs until the reaching of a balance between inner elastic force and strain applied to the wound hairs, when said locking means (9, 10) are deactivated.
