| description | The method for recognizing damage and determining the extent of the damage to a keratin-containing material, such as hair or wool, includes subjecting a sample of it in aqueous solution to an enzymatic and/or chemical treatment for proteolytic or hydrolytic degradation of the sample, and subsequently measuring the turbidity of the resulting liquid sample to determine the extent of the damage, either by visual observation with the naked eye or by physical measurement methods. An apparatus suitable for performing the method and enzymes, such as proteases and proteinases, and chemical agents for carrying out the method are also described. |
