150-180 / 1000+ results research Optimized Depilation Method and Comparative Analysis of Hair Growth Cycle in Mouse Strains
A new depilation method using cold wax reduces injury and improves hair growth studies in mice.
research Determination of the cuticula thickness of human and porcine hairs and their potential influence on the penetration of nanoparticles into the hair follicles
Nanoparticles penetrate hair follicles better when their size matches the cuticula thickness.
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 Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research Fractal geometry and topology abstracted from hair fibers
Hair fibers have fractal patterns with properties related to the golden mean, which may affect their functionality.
research Pseudofolliculitis barbae; current treatment options
Stopping shaving or removing hair follicles usually resolves Pseudofolliculitis barbae.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.
research Nanoindentation of Hair Cortex and Medulla Regions
research Acquired progressive kinking of hair affecting the scalp and eyelashes in an adult woman
A woman developed rare, unexplained curly hair on her scalp and eyelashes.
research Pseudofolliculitis cutis: a vexing disorder of hair growth
Pseudofolliculitis cutis causes painful skin bumps and needs proper shaving and treatments to manage.

Hairless mice lose hair by 3-4 weeks, develop thicker, folded skin, and show pigmentation differences.
research Pigmented vellus and upright regrowing hairs as the only predictive trichoscopic markers of hair regrowth in alopecia totalis and universalis
Pigmented vellus and upright regrowing hairs predict hair regrowth in severe alopecia.
research Changes in Characteristics of Murine Hair Follicles and Tissue Stem Cells Throughout Life
Mouse hair follicles age, causing more white hairs due to fewer pigment stem cells.
