The present study examines the ability of silicones to protect hair during heat styling, compared with other industry benchmarks and untreated hair. Also discussed are the mechanisms through which different silicones contribute heat protection in hair care products such as leave-in conditioners, serums and other product forms.

In vitro SPF measurements are challenged by reproducibility, repeatability and correlation with in vivo values. Here, the authors assess sunscreen adhesion to the test substrate support, since poor adhesion produces bad results. Surface substrates are characterized by functional group, charge, wettability and surface morphology. Eight w/o and o/w emulsions also are tested. Results indicate an ideal in vitro test substrate does not exist.
