This study examined the thermal conductivity of human hair using the Modified Transient Plane Source method, highlighting how frequent thermal, mechanical, and chemical treatments can damage hair by weakening its structure, particularly through changes in keratin that reduce elasticity.

In this study, researchers used the Modified Transient Plane Source method to measure the thermal conductivity of human hair, highlighting that common heat treatments can damage hair structure by altering its protein composition, emphasizing the importance of understanding thermal properties to mitigate such damage.

In this study, researchers found that the concentrations of cetostearyl alcohol, shea butter, and coconut oil significantly affected the in vitro spreadability of heat protectants, suggesting that optimizing these components could improve product coverage and thermal protection on hair.

This study reports that the candle flame technique "velaterapia," popular in Brazil for addressing split ends, can damage hair fibers due to bubble formation at high temperatures, despite thermal protectors providing some cuticle protection.

This study found that pretreatment with KP-Cryst fusion proteins effectively protected Asian and Caucasian virgin hair from thermal damage by maintaining higher water content and preventing structural changes during heat application.
