| Résumé : |
The health of human hair plays a crucial role in both male and female appearance, and has a strong psychological and social importance. Beautiful, strong and heatlhy hair is broadly desired. However, hair is highly exposed to harsh factors such as heat, chemical treatments, pollution and watering that can cause damage on the hair physicochemical properties, mainly in the hair cuticle.
There is great interest not only in developing products for the protection and recovery of damaged hair, but also in developing effective protocols to investigate the efficacy of innovative hair care products. Claims for cosmetic products, as well as hair care products, are a strategy to obtain successful marketing and promotion. The claims need to be substantiated by efficacy tests, whether they be in vivo, ex vivo or in vitro studies.
For high reliability, clinical studies should be designed, conducted, recorded and reported following good clinical practices principles to provide a unified standard for ICH (International Conference on Harmonisation) regions to facilitate the mutual acceptance of clinical data by regulatory authorities.
In this article, we present a range of hair testing techniques that can show damage sustained, from the cortex to the hair surface, for both quantitative and/or qualitative techniques.
In the interest of better understanding the complexity behind these techniques, it is important to make reference to the hair structure, as well as hair care products and how they act on the hair. This is because the knowledge of these matters will greatly facilitate the understanding of the techniques. |
