A comparative investigation of the protective effects of natural oils vs. silicones on African and Caucasian hair types

Hair is constantly exposed to physical stress due to washing and combing, as well as heat styling, to achieve desired appearance set by trends and personal preferences. As a consequence of these activities, hair develops undesirable sensory attributes. On the cellular level, the cuticle becomes lifted, fractured and gradually completely degrades, leaving cortex cells exposed and weakened mechanically.

As a result, protecting the hair with cosmetic treatments is quite important for maintaining a healthy appearance. The aim of this study was to determine the protective effects of two natural oils compared to two silicones on virgin Caucasian and African hair. For this, consumer behaviours in regarding to grooming habits had to be explored and materials with protective effects had to be determined. Protocols for testing were developed and performed and results were statistically analysed.
