30-60 / 1000+ resultsresearch Protein extraction from human anagen head hairs 1-millimeter or less in total length
A new method was developed to extract and analyze proteins from very short human hairs.
research Androgen receptors are only present in mesenchyme-derived dermal papilla cells of red deer (Cervus elaphus) neck follicles when raised androgens induce a mane in the breeding season
Red deer only have androgen receptors in neck hair cells for mane growth during breeding season.
research Variation in Muskox (Ovibos moschatus) Guard Hair Growth Rates: Implications for Measuring Chronological Biomarkers
Muskox hair growth rates vary widely, so a single growth rate can't be used for all populations.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research Some electron microscope observations on hardening in the human hair follicle
The hair follicle structure is more complex than thought, with new findings on protein formation.
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 A Prospective Longitudinal Study of Dynamic of Human Papillomavirus 6 and 11 Infection in Anogenital Hairs and Eyebrows of Male Patients with Anogenital Warts and Age-Matched Controls
HPV6/11 is often found in hair of men with anogenital warts, especially pubic hair, and can lead to recurrent warts.
research An Effective and Novel Technique for Hair Control in Craniofacial Surgery
A new method using bands and finger sheaths from gloves to manage hair during surgery is effective, quick, and reduces hair damage.
research Human hair keratins
research 001 Human scalp hair follicles are protected from alopecia areata in vivo by regulatory γδT cells
research Hair follicle morphogenesis and epidermal homeostasis in we/we wal/wal mice with postnatal alopecia
The we/we wal/wal mice have defects in hair growth and skin layer formation, causing hair loss, useful for understanding alopecia.
research Fine Structure of Perifollicular Nerve Endings in Human Hair
research Characteristics of the microscopic hair structure of domestic mammals from Equidae family
Donkey and horse hair have different microscopic structures, which can help tell them apart.
research HAIR COAT AND STEROIDAL IMPLANT EFFECTS ON STEERS GRA ZING NDOPHYTE-INFECTED TALL FESCUE DURING THE SUMMER
Steers with winter hair coats and reduced sweating struggled with heat, leading to less grazing and poor performance.
research 68 Follicular Unit Excision to Harvest Beard
Beard hair can be effectively used for hair transplants when scalp hair is insufficient.
research Exogen Hairs in Women with and without Hair Loss
Women with and without hair loss have similar amounts of exogen hairs, so these hairs are not a key factor in hair loss conditions.
research Pseudofolliculitis barbae: Review and Update on New Treatment Modalities
New treatments are available for managing ingrown hair inflammation.
research LGR5 is a conserved marker of hair follicle stem cells in multiple species and is present early and throughout follicle morphogenesis
LGR5 is a common marker of hair follicle stem cells in different animals and is important for hair growth and regeneration.
research Multidimensional Profiling of Human Body Hairs Using Qualitative and Semi-Quantitative Approaches with SR-XRF, ATR-FTIR, DSC, and SEM-EDX
Body hairs can be used in forensic science and toxicology like scalp hair.
research Transcriptome analysis reveals the genetic basis underlying the development of skin appendages and immunity in hedgehog (Atelerix albiventris)
The study found that certain genes are important for hedgehog skin appendage development and immunity, with spines possibly evolving for protection and infection resistance.
research Lonely Hair
Isolated long hairs at the original hairline can help diagnose Frontal Fibrosing Alopecia.
research Splitting Hairs: Evaluating the Origin of Human Nakedness
Humans likely became hairless to better regulate body temperature.
research The failure behavior of the anchorage of hairs during slow extraction
Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.
research Hormones and Hair Growth: Variations in Androgen Receptor Content of Dermal papilla Cells Cultured from Human and Red Deer (Cervus Elaphus) Hair Follicles.
Human hair growth is influenced by androgen hormones, and red deer mane follicles have similar hormone receptors.
research Structural features of the α-type filaments of the inner root sheath cells of the guinea pig hair follicle
α-type filaments in guinea pig hair follicles have unique structural features.
research Human hair morphology: a scanning electron microscopy study on a male Caucasoid and a computerized classification of regional differences.
Hair varies in size and features depending on body region.
research The Keratins of the Human Beard Hair Medulla: The Riddle in the Middle
Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.
research Cell proliferation during fibre growth initiation in ferret hair follicles
Ferret hair growth starts between 0 and 4 days after melatonin treatment, with cell growth peaking in the hair germ and declining as the hair matures.
research Growth pattern and turnover of carbon and nitrogen measured by stable isotope ratios in the hair of sika deer (Cervus nippon)
Shoulder guard hair best shows sika deer's diet.
