research Patients with profuse hair shedding may reveal anagen hair dystrophy: a diagnostic clue of alopecia areata incognita
Some people with heavy hair shedding might actually have a hidden form of alopecia, which can be identified by specific hair changes.
research Faculty Opinions recommendation of Live imaging of stem cell and progeny behaviour in physiological hair-follicle regeneration.
Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.
research The epidermal growth factor receptor decreases S tathmin 1 and triggers catagen entry in the mouse
EGFR helps mouse hair follicles stop growing by reducing certain growth regulators.
research Alopecia Areata in C3H/HeJ Mice Involves Leukocyte-mediated Root Sheath Disruption in Advance of Overt Hair Loss
Hair loss in mice starts with immune cells damaging hair roots before it becomes visible.
research Methods for Treating Androgenic Alopecia by Restoration of Morphogenetic Field Connectivity in Hair Follicle Networks
Restoring hair follicle communication may treat hair loss and improve sexual dysfunction.
research Comparative spatial transcriptomics of hair follicle-T cell interactions in mouse, dog and human reveals conserved drivers of primary cicatricial alopecia
Potential therapeutic targets for scarring hair loss are identified.
research Lonely Hair Sign: Not Specific for Frontal Fibrosing Alopecia
Hair diameter diversity is a key sign for diagnosing and managing male pattern baldness.
research Diffuse hypotrichosis from early childhood
The girl has a genetic hair condition causing thin hair since childhood.
research Cultured Peribulbar Dermal Sheath Cells Can Induce Hair Follicle Development and Contribute to the Dermal Sheath and Dermal Papilla
Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.
research Comparative Study of Some Potential Paracrine Factors Produced by Normal and Androgenetic Alopecia Hair Follicles
Balding hair follicles have less growth-promoting factors and more inhibitory factors, leading to hair loss.
research Resident human dermal γδT-cells operate as stress-sentinels: Lessons from the hair follicle
Human dermal γδT-cells respond to stress in hair follicles, contributing to hair loss.
research Evaluation of apoptosis regulatory markers in androgenetic alopecia
Apoptosis may contribute to hair loss in androgenetic alopecia.
research Preliminary study on reconstruction of hair follicle by cell mass of dermal papilla cells and bulge stem cells
Dermal papilla cells and bulge stem cells can help reconstruct hair follicles.
research The Ludwig pattern of androgenetic alopecia is due to a hierarchy of androgen sensitivity within follicular units that leads to selective miniaturization and a reduction in the number of terminal hairs per follicular unit
Ludwig pattern hair loss in women results from varying sensitivity in hair follicles, causing fewer visible hairs.
research Follicular dysplasia and hair loss in white-tailed deer (Odocoileus virginianus)
White-tailed deer can get a hair loss condition that might make them more vulnerable to environmental threats.
research Histology of the Human Hair Follicle
Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.
research Clinical, trichoscopic, and histopathologic characteristics of patients with alopecia and hypothyroidism: An observational study
Hypothyroidism patients with hair loss typically have thinning hair, smaller hair follicles, and normal hair shedding.
research Androgenetic alopecia: new insights into the pathogenesis and mechanism of hair loss (version 1; referees: 4 approved)
The arrector pili muscle plays a key role in hair loss in androgenetic alopecia.
research Characterization of Hair Follicles in Hirosaki Hairless Rats with Deletion of Basic Hair Keratin Genes. Enlarged Medulla, Loss of Cuticle and Long Catagen
Hirosaki hairless rats have sparse, twisted hair due to missing hair keratin genes.
research P02 Accelerated ageing of hair follicles in androgenetic alopecia
Hair follicles in androgenetic alopecia age faster, especially in the front.
research Follicular Stem Cells in Androgenetic Alopecia
Hair loss in Androgenetic Alopecia is not caused by damage to follicular stem cells.
research Morphological changes of the hair roots in alopecia areata: A scanning electron microscopic study
Scanning electron microscopy revealed four distinct hair root shapes in alopecia areata, suggesting a less invasive diagnostic method.
research Reconstructing protein conformations to activate follicular enzyme-nutrient reservoirs for reversing follicle aging
The microneedle patch helps regrow hair by restoring enzyme function in hair follicles.
research Heterotypic cell contacts and basal lamina morphology during hair follicle development in the mouse: a light, scanning, and electron microscopic study at the site of tissue interaction
Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.
research Inhibitory effect of 7DHC and BM15766 in HF organoid culture.
7DHC and BM15766 damage hair follicle structure and reduce key gene expression.
research Comparison of Alopecia areata in Human and Nonhuman Mammalian Species
The document concludes that certain rats and mice are useful for studying hair loss in humans and testing treatments.
research Characteristics of the structural components of pilosebaceous follicles in the differential diagnosis of non-cicatricial alopecia
Hair follicles are thinner in alopecia patients, especially in alopecia areata.
