Abstract:
The invention relates to a method for evaluating eyelash typology, that comprises the steps of: providing, particularly by display, at least two representations for evaluating the eyelash concentration within the fringe; acquiring a corresponding first piece of data; providing, particularly by display, at least two reference representations for evaluating the curvature of the eyelashes; acquiring a second corresponding piece of data; determining an eyelash typology at least from the first and second pieces of data.
Abstract:
The invention relates to a method of evaluating lip type, the method comprising the steps consisting in: supplying at least two reference representations enabling an observer to evaluate lip outline sharpness by comparing the representations against the lips being evaluated; acquiring corresponding first data; supplying at least two reference representations enabling the observer to evaluate the fleshiness of at least one lip; acquiring corresponding second data; and determining lip type from at least the first and second data.
Abstract:
L'invention est relative à un procédé d'évaluation d'une typologie de lèvres, comportant les étapes consistant à :- fournir au moins deux représentations de référence permettant à un observateur d'évaluer, par comparaison entre ces représentations et les lèvres à évaluer, la netteté du contour des lèvres,- acquérir (105) une première donnée correspondante,- fournir au moins deux représentations de référence permettant à l'observateur d'évaluer le caractère charnu d'au moins une lèvre,- acquérir (104) une deuxième donnée correspondante,- déterminer une typologie de lèvres à partir des première et deuxième données au moins.
Abstract:
A process and device are claimed for the cosmetic partial or complete lightening of hair colour. Hair is irradiated a lock at a time by passing through a laser beam strong enough to degrade the melamine in the hair, but not so strong that the keratin is damaged. Keratin in dark hair is degraded at a lower energy density than that in naturally light hair. Several irradiation passes are made on each lock of hair until the desired colour is achieved. The laser used has an energy density of 0.1-1.2 J/cm at a wavelength of 532 nm. The energy density used varies, proportional to the wavelength.
Abstract:
Process and device for the cosmetic partial or complete lightening of hair comprises irradiating the hair with a laser beam with impulses at a frequency of ≥ 10 Hz which degrades the melamine in the hair. Locks of hair are passed repeatedly through the laser beam until the desired colour is obtained. During treatment the hair is cooled to prevent heat damage.
Abstract:
Procédé de traitement de décoloration au moins partielle d'une mèche ou partie de mèche de cheveux, par irradiation de ladite mèche à l'aide d'un rayonnement laser sous forme d'impulsions, et dispositif pour sa mise en oeuvre. Le rayonnement laser a une puissance suffisante pour fournir, par exemple pour une longueur d'onde de 532 nm, une densité d'énergie de 0,1 à 1,2 J/cm2 parimpulsion. Cette densité d'énergie n'est pas supérieure à un seuil au-delà duquel la fibre kératinique des cheveux serait endommagée, ledit seuil étant d'autant plus faible que la couleur naturelle des cheveux à traiter est plus foncée.
Abstract:
The colorimetric measuring head (1), for determining the internal colour of a non-opaque material (2), in particular the internal colour of human skin, includes an optical system (3) which emits light towards the material to be studied and is separated by an oblique wall (4) for an optical system (5) which receives the light which has penetrated into and been reflected by the material. The external surface (A) of the head (1), which faces the material to be studied, is continuous and adapted to the surface of the material so as to match this surface either by direct application against the said surface of the material or with an optical wetting medium. The assembly is such that the light (R) received by the detector comes from inside the material (2), whilst the light possibly reflected by the surface of the material or coming directly from the emitter cannot reach the detector because of the opaque separating wall.
