TLDR The study found that certain conditioning compounds can penetrate hair and potentially improve its resistance to damage.
The document presents abstracts from the Journal of Cosmetic Science, including a study by Ruetsch and Kamath which used time-of-flight secondary ion mass spectrometry (TOF-SIMS) to investigate the penetration of low-molecular-weight cationic conditioning compounds into hair fibers. The study aimed to determine if these compounds simply reside on the hair surface or actually penetrate into the hair cortex. The findings suggested that penetration into the cortex could significantly improve hair's fatigue resistance. However, the document does not provide specific results or the number of hair samples analyzed, which are crucial for assessing the strength of the study. Additionally, the document includes other unrelated abstracts on topics such as the effect of hormonal cycles on skin properties, a novel method for visualizing hair lipids, and the penetration abilities of various oils into human hair fibers.
