research Hair That Is Difficult to Manage in a Hispanic Girl
A 9-year-old Hispanic girl has Uncombable Hair Syndrome, which may improve with age and biotin treatment.
research Evidence for calcium soaps in human hair shaft revealed by sub-micrometer X-ray fluorescence
Calcium soaps are present in human hair and can be removed with acid.
research Understanding Curly Hair Mechanics: Fiber Strength
Curly hair is mechanically different from straight hair and may need new testing methods.
research Hair Morphology in Androgenetic Alopecia
Abnormal cuticle and hair shaft medulla cause hair loss in androgenetic alopecia; sonography helps diagnose and manage it.

Disulfide bonds are crucial for hair's strength, especially when wet.
research Characterization of the Human Hair Shaft Cuticle–Specific Keratin-Associated Protein 10 Family
KRTAP10 proteins help form the hair shaft's tough outer layer by interacting with specific hair keratins.
research Morphological Approach to Hair Disorders
Accurate clinical, histological, and genetic methods are key for understanding and treating hair disorders.
research Proteomic tools for the investigation of human hair structural proteins and evidence of weakness sites on hair keratin coil segments
Hair proteins have weak spots in their α-helical segments.
