摘要:
System for the simulation of the evolution of a region of the scalp of a subject over time, comprising a means of observation of the said hair region able to output digital observation data, a first digital data processing means capable of classifying elementary parts of the said region on the basis of the observation data, a second digital data processing means capable of simulating the evolution of the said hair region as a function of the data emanating from the first digital data processing means, and a means of displaying the data emanating from the second digital data processing means.
摘要:
The invention relates to the use in a composition for caring for human hair or eyelashes of an effective amount of a pyridinedicarboxylic acid derivative of general formula (I) or of one of its salts, in which R1 and R2 represent, independently of one another, OH, OR′, —NH2, —NHR′ or —NR′R″, and R′ and R″ represent, independently of one another, a saturated or unsaturated and linear or branched C1-C18 alkyl radical or an aryl radical, this alkyl or aryl radical optionally being substituted by at least one OH, alkoxy, acyloxy, amino or alkylamino group, or R′ and R″ together represent a heterocycle, the composition being intended to induce and/or stimulate the growth of human keratinous fibers, such as the hair and eyelashes, and/or slow down their loss; the invention also relates to a cosmetic treatment intended to stimulate the growth of human keratinous fibers, such as the hair and eyelashes, and/or slow down their loss.
摘要:
System for the simulation of the evolution of a hair region of the scalp of a subject over time, comprising a means of observation of the said hair region able to output observation data, a first processing means capable of classifying the hairs of the said region on the basis of the observation data and of external data, a second processing means capable of simulating the evolution of the hairs as a function of the data emanating from the first processing means, and a means of displaying the data emanating from the second processing means.
