1. An arrangement for determining external damage to hair, the arrangement comprising:
a reading unit, which is designed to obtain optical features of hair and wherein the reading unit is adapted to obtain the optical features from an optical detection unit;
a processing unit, which is designed to receive the optical features from the reading unit and to determine surface properties of the hair from the optical features;
wherein the processing unit implements a pattern recognition algorithm to determine the surface properties of the hair including a shape of a cuticle cell of the hair, a protrusion of the cuticle cell of the hair and a visibility of an endocuticle, and is adapted to assign, by employing the pattern recognition algorithm, the surface properties to a predetermined damage including a damage type and an associated damage level and to output the damage type and the damage level to an evaluation unit, wherein the pattern recognition algorithm is an artificial neural network comprising an input layer, at least one hidden layer and an output layer; and
the evaluation unit for determining a treatment agent in response to a comparison of the damage type and the damage level with a predetermined damage type and a predetermined damage level.
