Disclosed is a method with different exemplary embodiments for determining a degree of damage to hair. Said method can comprise the following steps: during the exposure of a hair sample to near-infrared and/or infrared light, recording a spectrum of at least part of the near-infrared and/or infrared light that has interacted with the hair sample, comparing at least part of the spectrum with a spectroscopic calibration model obtained by near-infrared and/or infrared spectra and degrees of damage of a plurality of calibration hair samples, and determining the degree of damage to the hair using said comparison.

An arrangement for determining a degree of stretching of hair is provided. The arrangement includes a detection unit for detecting hair characteristics and an evaluation unit for evaluating the detected hair characteristics and for determining the degree of elongation of hair based on the detected hair characteristics. The detection unit contains a near-infrared sensor, and is configured to irradiate a hair sample with electromagnetic waves in the infrared range and to detect an absorbance of the hair sample in a wavelength range from about 800 to about 2500 nm. The acquisition unit is configured to generate an absorption spectrum of the hair sample in the wavelength range of from about 800 to about 2500 nm and provide it to the evaluation unit and the evaluation unit is configured to compare the generated absorption spectrum with a calibration model and to determine a degree of elongation of the hair sample.
