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 Mimicking Hair Disorders by Genetic Manipulation of Organ-Cultured Human Hair Follicles
Scientists can mimic hair disorders by altering genes in lab-grown human hair follicles, but these follicles lack some features of natural ones.

Hair cortisol levels can show increased stress during late pregnancy but only for up to six months.
research Hair through the female life cycle
Women's hair generally gets thinner and less dense starting in their mid-thirties, with hair loss becoming more common as they age due to both genetics and environment.
research Hair biology: an update
Recent findings show that hair growth and color are controlled by a complex network of signals in the hair follicle.
