Human hair cuticle has five cell layers with specific junctions and granules.
research Omics for Precious Rare Biosamples: Characterization of Ancient Human Hair by a Proteomic Approach
The study developed a method to analyze ancient hair proteins using very small samples.
research In vivo formation steps of the hard α-keratin intermediate filament along a hair follicle: Evidence for structural polymorphism
Hair follicles form hard α-keratin filaments in four steps, showing structural differences.
research Miniaturized hairs maintain contact with the arrector pili muscle in alopecia areata but not in androgenetic alopecia: A model for reversible miniaturization and potential for hair regrowth
Miniaturized hairs stay connected to muscle in alopecia areata, allowing possible regrowth, but not in androgenetic alopecia.
research Plica neuropathica: Bird's nest under dermatoscope
Plica neuropathica is a tangled hair condition that may be caused by hair damage or psychiatric issues and is treated by cutting the hair and addressing mental health.
research Force-triggered density gradient sedimentation and cocktail enzyme digestion treatment for isolation of single dermal papilla cells from follicular unit extraction harvesting human hair follicles
New methods efficiently isolate dermal papilla cells from hair follicles, preserving their characteristics better than traditional methods.
research Hair shaft disorders: a rare case series
The document concludes that proper diagnosis and treatment of hair shaft disorders require understanding their unique causes and avoiding hair-damaging practices.
research Hair Shafts in Trichoscopy
Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.
research Exogen involves gradual release of the hair club fibre in the vibrissa follicle model
Hair sheds gradually from the follicle, with readiness to shed indicated by less attachment material.
research Light Microscopic Hair Abnormalities in Children: Retrospective Review of 119 Cases in a 10-Year Period
Over half of the children had abnormal hair under a microscope, with many having genetic hair conditions.
research Histologic Study of the Regeneration Process of Human Hair Follicles Grafted onto SCID Mice after Bulb Amputation
Human hair follicles can regenerate and recover after severe injury by going through a brief abnormal resting phase before growing again.
research The distribution of melanocytes and the degradation of melanosomes in fetal hair follicles
Fetal hair follicles have melanocytes with melanosomes at different stages, which are broken down into pigment particles in keratinocytes.
research Known and Unknown Features of Hair Cuticle Structure: A Brief Review
The hair cuticle is made of tough proteins that protect the hair, but more research is needed to fully understand its structure.
research Monilethrix: an ultrastructural study
Monilethrix hair issues are due to problems in the hair's internodes.
research Trichoscopy I: Non-Cicatricial Alopecia
The document concludes that different patterns of hair thickness and scalp changes can help diagnose types of non-scarring hair loss.
research Tribological Properties between Taut Hair Fibers in Wet Conditions: A New Shampoo Formulation for Eliminating Stick‐Slip Friction
Shampoo B, which uses water-soluble silicone, is better at detangling hair in wet conditions due to its two-layer conditioning film.
research Follicles Twisted During Follicular Unit Excision Could Survive in the Skin of Nude Mice
Twisted hair follicles can survive transplantation as well as intact ones.
research HAIR AND HAIR CARE: AN OVERVIEW
Eating well and avoiding synthetic hair products are key for healthy hair.
research Follicular Unit Plain Speak
The conclusion is that hair transplant surgery should use microscopically dissected natural hair groupings and some new terms were suggested for clarity.
