A more realistic test would involve all the elements--fiber bending (flexure), abrasion and extension--encountered in normal hair fracture. This paper provides background about a test method that does measure an amalgamation of these three elements, and gives examples of its use to evaluate a new ingredient for hair products that increases the strength of bleached hair.

Titre : Moisture Regulation of Hair by Cosmetic Proteins as Demonstrated by Dynamic Vapour Sorption- A Novel Efficacy Testing Technique Type de document : texte imprimé Auteurs : Surinder P. Chahal, Auteur ; Nicolas I. Challoner, Auteur ; R. T. Jones, Auteur Année de publication : 2000 Article en page(s) : p. 19-25 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.5 Parfums et cosmétiques Résumé : Dynamic Vapour Sorption has been evaluated as a novel efficacy-testing tool for determining the moisture retention properties of hair when treated with hydrolysed proteins. We have been able to demonstrate that hydrolysed proteins, when applied to hair from leave-on and rinse-off treatments, can increase the equilibrium moisture content of hair and also influence the kinetics of moisture tranfer. Studies have shown that certain hydrolysed proteins can reduce the rate of moisture uptake by hair at high relative humidity and reduce the rate of moisture loss at low relative humidity.
