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 Torsional behavior of human hair
Water makes hair more flexible, especially the outer layer.
research Trichostasis Spinulosa of the Heel: Unique Presentation with Characteristic Morphology
A rare skin condition usually on the face was found on a man's heel.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research Bubble hair
Bubble hair deformity may be caused by hair shaft trauma and can improve with gentle hair care.
research Intrinsic curvature in wool fibres is determined by the relative length of orthocortical and paracortical cells
Wool fibre curvature is due to longer orthocortical cells compared to paracortical cells.

A rare neck cyst in a 47-year-old man showed diverse skin cell types and was not linked to HPV.
research Cross-Sectional Study of Hairline Shape among the Idoma People of Benue State, Nigeria
Most Idoma people have a curved hairline due to genetics.
research Curl secret in cells
Hair curliness is caused by the arrangement and length of two different cell types.
research Malassezia Display a Hyphae-like “Spaghetti-and-Meatballs” Configuration in Keratotic Plugs
Malassezia fungi in healthy noses can form a "spaghetti-and-meatballs" structure.
research Scalable biofabrication and morphology evaluation of tissue spheroids
research Orientation of Multi-Hair Follicles in Nonbald Men
Most nonbald men's multi-hair follicles are naturally positioned perpendicular to a line from the scalp's crown, which is important for natural-looking hair transplants.
research Curly Hair Follicle is Sculpted by a Contracted Arrector Pili Muscle. A Hypothesis with Treatment Implications
Curly hair may be caused by a muscle contraction, and muscle relaxants might help treat it.
research New Aspects of the Structure of Human Scalp Hair-II: Tubular Structure and Material Flow Property of the Medulla.
The medulla in Asian scalp hair has a tubular structure that allows ions and large molecules to flow through it.
research An investigation of the association between structural proteins and lipids with scalp hair curvature
Lipids play a key role in determining hair curvature.
