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).

Abstract: A method for assessing the state of hair by releasably engaging a first end of hair fibers with a holder which so that an opposite, second end of said hair fibers hangs free and applying sufficient force to the second end of the hair fibers such that the hair fibers at the first end are pulled from the holder.
