research Deciphering the molecular morphology of the human hair cycle: Wnt signalling during the telogen–anagen transformation
Wnt signaling is important for the change from the resting phase to the growth phase in human hair cycles.
research Histopathologic Evaluation of Alopecias
The document concludes that accurate diagnosis of different types of hair loss requires careful examination of hair and scalp tissue, considering both clinical and microscopic features.
research Clinicopathological insights into the phenotypic variation of autosomal recessive hypotrichosis/wooly hair by c.736T>A LIPH mutation
The conclusion is that the variation in hair thinness in patients is mostly due to the amount of underdeveloped hairs, and treatments that thicken fine hairs might work for those with mild to severe conditions.
research A patient with diffuse hair loss
The patient's hair loss is most likely due to diffuse alopecia areata.
research Hair diameter diversity: a clinical sign reflecting the follicle miniaturization.
Different thicknesses of hair strands can indicate the severity of hair thinning.
research Atrichia with papular lesions resulting from a novel insertion mutation in the human hairless gene
Researchers found a new mutation causing total hair loss from birth.
research Histopathological Analysis on keratin2-6 g Expression in Hair Mutant Mouse Hague
Keratin2-6g is crucial for hair follicle development, with mutations causing cell degeneration and vacuolation.
research Hair: more than just an appendage
A boy and his father with hereditary hypotrichosis simplex were treated for hair loss, but the treatment result is unknown.
research Novel D323G mutation of DSG 4 gene in a girl with localized autosomal recessive hypotrichosis clinically overlapped with monilethrix
A new DSG4 gene mutation causes hair defects in a young girl.
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 The Stem Cell Quiescence and Niche Signaling is Disturbed in the Hair Follicle of the Hairpoor Mouse, an MUHH Model Mouse.
Hair follicle stem cells in hairpoor mice are disrupted, causing hair loss.
research Dissociated Human Dermal Papilla Cells Induce Hair Follicle Neogenesis in Grafted Dermal–Epidermal Composites
Human skin cells can create new hair follicles when transplanted into mice.
research Hair Biology and Androgenetic Alopecia
Hair loss caused by genetics and hormones; more research needed for treatments.
research Hair Anomalies in a 6-Year-Old Girl
A 6-year-old girl was diagnosed with a rare hair disorder called monilethrix.
research Pathogenesis of androgenetic alopecia
Androgenetic alopecia, or hair loss, is caused by a mix of genetics, hormones, and environment, where testosterone affects hair growth and causes hair to become smaller and grow for a shorter time.
research Bald scalp in men with androgenetic alopecia retains hair follicle stem cells but lacks CD200-rich and CD34-positive hair follicle progenitor cells
Men with baldness due to androgenetic alopecia still have hair stem cells, but lack specific cells needed for hair growth.
research Hair Follicle Dermal Stem Cells Regenerate the Dermal Sheath, Repopulate the Dermal Papilla, and Modulate Hair Type
Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.
research Hair repigmentation in microcystic adnexal carcinoma
Hair repigmentation can indicate malignancy and should be investigated.
research Pediculosis
Scalp biopsies are important for diagnosing hair loss conditions.
research The Evolution of the Promise of Hair Cloning: How Hair Cell Cloning Will Fit Into Your Practice
Hair cell cloning could potentially rejuvenate shrinking hair follicles, allowing for lifelong hair maintenance.
research Characterization of hair follicles in Hirosaki hairless rats with deletion of basic hair keratin genes : enlarged medulla, loss of cuticle and long catagen
research Editors' Picks
Scientists found gene mutations that affect hair loss, skin stem cells, and skin disorders, and identified drugs that may help treat blood vessel and skin conditions.
research [Androgenetic alopecia. Denser hair growth on two-thirds of balding scalps].
research Acquired Progressive Kinking of the Hair
Curly hair in certain scalp areas can be an early sign of hair loss.
research Hormone-induced aberrations in electromagnetic adhesion signaling as a developmental factor of androgenetic alopecia
Hormones cause hair loss by affecting cell growth and weakening cell attraction.
research Papular atrichia
An 8-year-old girl has a rare, irreversible hair loss condition caused by a genetic mutation.
research Hair Follicle Signaling Networks: A Dermal Papilla–Centric Approach
The document concludes that dermal papilla cells are key for hair growth and could be used in new hair loss treatments.
research A newly discovered linkage between proteoglycans and hair biology: decorin acts as an anagen inducer
Decorin, a protein, may help start hair growth and could be used to treat hair loss.
research 1325 Extensive hair growth stimulation and follicle normalization with transplanted hair follicle associated pluripotent (HAP) stem cells in athymic nude mice
Transplanted stem cells from hair follicles significantly boosted hair growth and normalized follicles in certain mice.
