    摘要: A device for measuring hair properties has a first part (I) and a second part (II) between which hair (H) is guided. The first part (I) comprises a measuring probe (MP), and the second part (II) is arranged for deforming the hair (H) against the measuring probe (MP). While the device moves along the hair (H), the measuring probe (MP) experiences both a friction force resulting from the hair (H) being guided along the measuring probe (MP), and a deformation force (DF) resulting from the hair (H) being deformed by the second part (II) against the measuring probe (MP). Advantageously, the second part (II) comprises a pressure element (PB, S) for pressing the hair (H) against the measuring probe (MP), to squeeze the hair (H). In alternative embodiments, the second part (II) comprises alignment elements (AE) at opposite sides of the measuring probe (MP) for bending the hair (H) against the measurement probe (MP), and guidance elements (G) for mitigating an influence of an angle at which the device is applied to the hair (H) to the friction force and/or the deformation force, while the measuring probe (MP) is mounted to a load cell module (LC-X, LC-Y) for measuring a load in two dimensions to measure friction and deformation force, respectively.
