    • The invention relates to a method of generating a synthesized image of a hair, comprising the following steps: calculating the shape of the hair by applying a behavioral relationship determining the shape of the hair as a function of a physical parameter linked to a mechanical property of the hair, in particular the linear density; producing an image of the hair of shape that has been calculated in this way. The behavioral relationship may be given by the minimization of the following function: E = K L ⁢ ∫ 0 1 ⁢ [ 1 2 ⁢ ( k ~ ⁡ ( s ~ ) - α ) 2 + 1 β ⁢ z ~ ⁡ ( s ~ ) ] ⁢ ⅆ s ~ , where α=Lk0 and β=K/gμL3, and where L designates the length of the hair, k0 its spontaneous curvature, K its bending moment, μ its linear density and g the acceleration due to gravity, {tilde over (s)} the curvilinear abscissa relative to the length of the hair, {tilde over (k)} its local curvature relative to its length and {tilde over (z)} its height relative to its length.

    • A device for evaluating the creasing of the skin in vivo. A zone of the skin to be examined is creased. The zone of the creased skin is scanned with an incident luminous beam which is emitted by a light source. The light reflected by the creased skin is detected. The detected light is converted into an electrical signal. At least one parameter representing the profile of the creased skin is extracted from the electrical signal. This device makes it possible to evaluate the mechanical properties of the dermis, such as its elasticity and firmness and the aging of the skin, as well as to evaluate the effectiveness of products intended to counteract such aging.
