Acquired Progressive Kinking of Hair is likely an early sign of male pattern baldness.
research The toughening transition in hair keratin
The observed "toughening" in keratin was actually due to water evaporation, not a real change in keratin.
research Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.

research Morphological changes of the hair roots in alopecia areata: A scanning electron microscopic study
Scanning electron microscopy revealed four distinct hair root shapes in alopecia areata, suggesting a less invasive diagnostic method.
research Fibrosing Alopecia in a Pattern Distribution
Fibrosing alopecia in a pattern distribution is a new type of scarring hair loss that resembles common baldness and an autoimmune skin disease.
research Trichoscopy pattern in alopecia areata: A systematic review and meta‐analysis
Yellow dots and short vellus hairs are the most common signs of Alopecia Areata (AA), and trichoscopy can help diagnose AA and track treatment progress.
research Charge density alterations in human hair fibers: an investigation using electrostatic force microscopy
The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
research A case of altered hair texture after resolution of alopecia areata
New hair after alopecia areata can be thinner and change color but usually keeps the same shape.
