The invention relates to a method of generating at least one synthesized image of at least a portion of a head of hair in movement, the method comprising the steps consisting in calculating a shape of at least one director hair by applying to the at least one director hair at least one mechanical model of an inextensible rod having inertia and stiffnesses in twisting and in bending, and in generating at least one virtual image of the at least one portion of the head of hair from the shape of the director hair.

According to the process for applying reshaping to hair by use of a hair-curler, the hair-curler (1) is arranged in such a way that the perimeter along which the lock of hair (M) is rolled increases by approx. 2 to 3% when its temperature rises to pass from a starting temperature to a higher temperature which nevertheless remains lower than a relatively low limit thus avoiding the burning of the hair and/or of the scalp; the longitudinal section of the curler is sufficient to withstand the stresses imposed by elongation of the lock of hair; the lock of hair is rolled around the curler at the starting temperature so that the hair is retained against the hair-curler; the curler is raised to the said higher temperature; the hair is thus subjected to elongation ensuring an increase in the life of the reshaping applied to the hair.
