A recent study* has validated the use of a TA.XTplus texture analyser for evaluating objectively the effectiveness of personal care products on the physical characteristics of hair. The study highlighted how analytical technology can help the industry substantiate ambitious marketing claims about shampoos and conditioners that claim to leave hair soft and manageable.
In the study, carried out by Croda, the bending force of a hair bundle was measured as an indicator of hair softness. The TA.XTplus was used to determine the bending modulus of different types of hair, comparing results before and after the application of various hair treatments.
