Human hair varies in structure based on curl type, with high curl hair showing the most differences.
research Characteristic microstructure of curved human hair
Curved human hair has different structures on its convex and concave sides.
research Curl secret in cells
Hair curliness is caused by the arrangement and length of two different cell types.
research Human hair form. Morphology revealed by light and scanning electron microscopy and computer aided three-dimensional reconstruction.
Hair follicle shape determines hair type: curly, straight, or in-between.
research Hair shape of curly hair
Curly hair shape is determined by the hair bulb.

research The biology of hair shape
Hair shape is determined by genetic, molecular, and cellular factors.
research Hair curvature: a natural dialectic and review
The document concludes that hair curvature can be explained by the growth patterns caused by the shape and separation of cells in the hair follicle and is affected by specific molecular pathways.
research Acquired curved hair is caused by fusion of multiple hair matrix cells
Curved hair can develop when hair cells merge abnormally during growth.
research Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.

A woman developed rare, unexplained curly hair on her scalp and eyelashes.
research Shape Variability and Classification of Human Hair: A Worldwide Approach
Human hair can be classified into eight types based on physical features, not ethnicity.
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 Understanding Curly Hair Mechanics: Fiber Strength
Curly hair is mechanically different from straight hair and may need new testing methods.
research Development and sensory analysis of shampoo for curly hair
The shampoo effectively defines and models curls while reducing frizz and volume.
