Instrumental Combing for Manageability
The primary technical function of most conditioning products is to lubricate the hair surface; and, in doing, so facilitate manageability and mediate degrading feel properties. Thus, protection, conditioning and manageability claims often arise from demonstrating an ability to quantify the degree of lubrication. A common, and highly consumer-relevant, approach for measuring this lubrication involves an instrumental combing experiment.
Experiments can be performed in either the wet or dry states and generally involve assessing treatment procedure(s) relative to an unconditioned control. Our testing approach evaluates frictional forces while a hair tress is pulled through a comb.
