New resin B makes artificial hair fibers hold curls longer than traditional resin A.

This systematic review found that sole nanofat grafting in plastic and reconstructive surgery shows potential benefits for scar improvement and anti-aging, with increases in skin thickness, collagen, and elastic fibers, but the evidence level remains low and further research is needed.

The document describes a method for preparing hair for microscopy by embedding it in plastic, cutting it, and storing it cold before imaging.

This study found that examining hair morphology provides deeper insights than classification, suggesting a potential population stratification artefact between hair curvature and cross-sectional shapes in the examined admixed African-European sample.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.
