Caffeine affects hair growth and health differently in men and women.
research The effect of 1,25-dihydroxyvitamin D3 on the growth and differentiation of cultured human outer root sheath cells from normal subjects and patients with vitamin D-dependent rickets type II with alopecia
research Proliferating trichilemmal cyst with histological malignant transformation: Identification of hair sheath keratins in the tumor.
A hair cyst can become cancerous, showing specific keratins from the hair sheath.
research Seborrheic karatosis, a tumor of the infundibular and isthmus of hair follicles: Identification of hair sheath keratins and histopathological features suggesting hair follicle origin.
Seborrheic keratosis likely originates from the upper regions of hair follicles.
research Nestin expression in hair follicle sheath progenitor cells
Nestin is found in hair follicle progenitor cells, linking them to neural stem cells.
research Woolly Antics between the Sheaths
Lipase H is important for hair follicle function and shaping hair fibers.
research 862 Defining the molecular signature of the hair follicle dermal sheath and its functional requirement for hair cycle progression during catagen
The hair follicle dermal sheath is essential for hair shedding and needs to communicate with the outer root sheath for normal hair growth cycles.
research Alopecia Mucinosa
Alopecia mucinosa is a challenging condition with unclear diagnosis and treatment.
research 5α-Reductase activity in the human hair follicle concentrates in the dermal papilla
The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.
research LOOSE ANAGEN SYNDROME AND LOOSE ANAGEN HAIR
Loose Anagen Syndrome causes easy-to-pull, thin hair, mainly in young girls, and improves with age.
research Loose anagen hair syndrome in children of Upper Egypt
Loose Anagen Hair syndrome occurs in dark-skinned children and often improves on its own.
research Cetuximab-induced hypertrichosis of the scalp and eyelashes
A cancer drug caused unusual hair growth on a 100-year-old man's scalp and eyelashes.
research The hair shaft: normality, abnormality, and genetics
Hair microscopy is useful for diagnosing hair disorders, but clear definitions are needed for accurate genetic analysis.
research Casts and pseudocasts
It's important to tell the difference between hair casts, pseudocasts, and nits.
research A rare pediatric case of loose anagen hair syndrome
Loose anagen hair syndrome in children may improve with age, but treatment results vary.
research Rekindling the lost hair‐forming world
Non-hairy skin cells might be used to regenerate hair, helping with baldness and skin wounds.
research Spatiotemporal Expression Characterization of KRTAP6 Family Genes and Its Effect on Wool Traits
KRTAP6 genes affect wool quality in sheep.
research Study on the distribution of hair keratin in normal hair follicles by immunohistochemical staining
Different keratins in hair follicles can help identify hair tumor origins.
research [Immunohistochemical study on the keratin expression in generating rat hair tissues using anti-hair keratin monoclonal antibodies].
Hair germ cells differ from epidermal cells in keratin expression, and specific keratins form after hair differentiation.
research Inductive Properties of Hair Follicle Cells
Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.
research CD10 and CD34 in fetal and adult human hair follicles: dynamic changes in their immunohistochemical expression during embryogenesis and hair cycling
CD10 and CD34 levels change during hair development and different hair growth stages, which could be important for hair regeneration treatments.
research Immunocytochemical Localization of Androgen Receptors in the Scalp of the Stumptail Macaque Monkey, a Model of Androgenetic Alopecia
Androgen receptors found in monkey scalps, similar to humans, affect hair growth.
research Environment of the Anagen Follicle
The document concludes that hair follicles have a complex environment and our understanding of it is growing, but there are limitations when applying animal study findings to humans.
research Vainas peripilares
The girl's "dandruff" was actually harmless hair casts, not a hygiene issue.
research Isolation and cultivation of the cells of hair follicles in vitro,and observation of the biological characteristics of them.
Cells from the upper hair follicle grow more actively, suggesting stem cells may be located there.
research 575 An extract of Leontopodium alpinum prolongs anagen phase in human hair follicles ex vivo
Leontopodium alpinum extract may help reduce hair shedding by keeping hair in the growth phase longer.
research A Contemporary View on Felix Pinkus’ Concept of the Vitreous Membrane
The vitreous membrane in hair follicles changes shape during the hair cycle and may affect hair growth and nutrient exchange.
