research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research Control of Human Hair Growth by Neurotrophins: Brain-Derived Neurotrophic Factor Inhibits Hair Shaft Elongation, Induces Catagen, and Stimulates Follicular Transforming Growth Factor β2 Expression
Brain-Derived Neurotrophic Factor (BDNF) slows down hair growth and promotes hair follicle regression.
research Ultrastructural localization of hair keratins, high sulfur keratin-associated proteins and sulfhydryl oxidase in the human hair
Hair proteins change location and structure as hair cells mature.
research Expression patterns of the glial cell line–derived neurotrophic factor, neurturin, their cognate receptors GFRα-1, GFRα-2, and a common signal transduction element c-Ret in the human skin hair follicles
Certain proteins and their receptors are more active during the growth phase of human hair and could be targeted to treat hair disorders.
