Automated Measurement of Spatially Resolved Hair-Hair Single Fiber Adhesion. [PDF]
Langmuir, 2019 The adhesion force between individual human hair fibers in a crosshair geometry was measured by observing their natural bending and adhesive jumps out of contact, using optical video microscopy.

Understanding Curly Hair Mechanics: Fiber Strength [PDF]
Journal of Investigative Dermatology, 2020 The relationship between the geometric and mechanical profiles of hair fibers has been studied, with special focus on curly samples. Incidental observations pointed to a significantly different viscoelastic character with varying curliness. Further investigations confirmed initial observations, showing an initial distinct toe region behavior for curly ...

SK2 channels are required for function and long-term survival of efferent synapses on mammalian outer hair cells [PDF]
, 2009 Cochlear hair cells use SK2 currents to shape responses to cholinergic efferent feedback from the brain. Using SK2-/- mice, we demonstrate that, in addition to their previously defined role in modulating hair cell membrane potentials, SK2 channels are ...

Morphological analysis of polymers on hair fibers by SEM and AFM
Materials Research, 2003 The polyquaternium 7® polymer is widely used in cosmetic formulations. Morphologic alterations in hair fibers were observed after the application of the polyquaternium 7® polymer, using SEM and AFM.
