  • Method for measuring wet friction of hair
    Patent number: 11879831
    Abstract: A method of measuring a wet friction of a bundle of hair, using a system which includes a friction probe having a contact surface and fitted with a weight in the range of from 10 g to 500 g, inclusive, a means for securing the bundle of hair, and a water bath, the friction probe being connected to a texture analyser, the method including the step of i) providing a bundle of hair fibres. The method also includes the steps of ii) aligning the bundle of hair fibres; iii) securing the bundle of hair fibres; iv) immersing the bundle of hair fibres under water in the water bath; v) contacting the bundle of hair fibres with the contact surface of the friction probe, which is fitted with the weight; vi) moving the probe along the hair fibres; and vii) recording the friction generated under step vi).
