Two Hispanic women developed Plica neuropathica, a condition causing tangled hair, possibly due to hair damage and various risk factors.
research The Secrets of Beautiful Hair: Why is it Flexible and Elastic?
Beautiful hair is flexible and elastic due to its unique double-layered structure and can be enhanced with succinic acid treatment.
research Bubble hair – a possible explanation for its distribution
Using a blow dryer in a certain way can cause localized hair damage with bubble formation inside the hair.
research Acquired progressive kinking of the hair in a Korean female adolescent
A Korean girl developed kinky hair without known cause or effective treatment.

research An ultrastructural study on corkscrew hairs and cigarette‐ash‐shaped hairs observed by dermoscopy of tinea capitis
Corkscrew and cigarette-ash-shaped hairs in tinea capitis are caused by internal hair degradation and external resistance.
research X-rays studies of the structure of hair, wool, and related fibres. II. - The molecular structure and elastic properties of hair keratin
Stretched hair has a similar structure to natural silk, showing hair's elasticity involves reversible changes within its molecules.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
