research Mitotic processes in hair follicles and the morphostructure of sheep skin upon inclusion of a water-soluble fatty acid complex into their diets
Adding a water-soluble fatty acid complex to sheep diets improves wool growth by increasing primary hair follicle size and density.
research How a Bird Gets Its Feathers: Insights from Chromatin Looping
Feather patterns are influenced by enhancers and chromatin looping, and the structure of protein complexes important for hair growth has been detailed.
research Spatial variation and associated genes of total hair follicle density in goats
Four genes affect hair follicle density in goats.
research Woolly hair nevus
A 17-year-old developed woolly hair nevus in adolescence, which is unusual, and over time the hair darkened and straightened slightly, but microscopic changes persisted.

research A hair abnormality in Abyssinian cats
Abyssinian cats can have a hair abnormality that makes their coat look rough and dull.
research Human hair keratin network and curvature
Curly hair shape is due to uneven growth patterns in the hair follicle.
research Keratins: the hair shaft's backbone revealed
Keratins are crucial for hair strength, and mutations in certain keratin genes cause hair disorders.
