960-990 / 1000+ results research Pseudofolliculitis cutis: a vexing disorder of hair growth
Pseudofolliculitis cutis causes painful skin bumps and needs proper shaving and treatments to manage.
research Selective follicular targeting by modification of the particle sizes
Medium-sized particles penetrate hair follicles better than smaller or larger ones, which could improve delivery of skin treatments.
research Different patterns of 5α-reductase expression, cellular distribution, and testosterone metabolism in human follicular dermal papilla cells
Androgen effects on hair follicles vary by skin area.
research Trichostasis Spinulosa
The study found clear differences in lesion distribution and microscopic features among trichostasis spinulosa, keratosis pilaris, and eruptive vellus hair cysts.
research The supplemental materials of “Association of Fibrosis in Bulge Portion with Hair Follicle Miniaturization in Androgenetic Alopecia”.
research Development of a novel, clinically-relevant model for investigating factors that stimulate human hair growth
Testosterone stimulates growth in intermediate hair follicles, but this can be blocked by cyproterone acetate.
research 1377 Decoding frontal fibrosing alopecia and lichen planopilaris: Macrophages hold the key?
Macrophages are more involved in Lichen planopilaris than in Frontal fibrosing alopecia.
research Interaction between dermal papilla cells and follicular epithelial cells in vitro: effect of androgen.
Testosterone helps beard and axillary hair cells grow by releasing growth factors from dermal papilla cells.
research Growth Factors, Cell-Cell and Cell-Matrix Interactions in Skin during Follicle Development and Growth
research Variation of Hair Follicle Counts among Different Scalp Areas: A Quantitative Histopathological Study
Hair count values should be standardized for each scalp region to evaluate hair disorders in Asians.
research Follicular Density and Ratios in Scarring and Nonscarring Alopecia
Nonscarring alopecia has higher hair density than scarring alopecia, and hair density can help diagnose the type of alopecia.
research Cyclosporine-induced folliculodystrophy
Cyclosporine can cause a unique skin condition called "cyclosporine-induced folliculodystrophy."
research Dandruff lesional scalp skin exhibits epidermal T cell infiltration and a weakened hair follicle immune privilege
Dandruff is linked to increased T cells and weakened immune protection in hair follicles.
research Rapidly progressive diffuse fibrosing alopecia
These hair loss conditions might be part of a spectrum, not separate issues.
research Optical coherence tomography-assisted diagnosis of follicular keratosis of the chin
OCT can non-invasively diagnose follicular keratosis and other hair follicle disorders.
research Proliferation and differentiation of cultured human follicular keratinocytes are not influenced by biotin
research Keratin formation in the hair follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research Alarm reaction of pilosebaceous apparatus
The hair and oil glands react by changing structure when stressed.
research Keratosis Pilaris and Scarring Alopecia
The man's scarring alopecia and skin issues did not improve with treatments.
research Non-scarring Alopecias in Iranian Patients: A Histopathological Study With Hair Counts.
The most effective way to diagnose non-scarring hair loss is by transverse sectioning, and some cases, particularly in males with inflammation around hair follicles, might be curable.
research Keratosis follicularis spinulosa decalvans in a family
KFSD is a genetic disorder causing hair loss and skin issues, with no effective treatment.
research Histochemistry of the human hair follicle with consideration of anagen phases I to VI
Human hair follicles have a unique cell distribution and differentiation pattern during growth.
research Transfollicular drug delivery—Is it a reality?
Hair follicles may soon be used more for targeted and systemic drug delivery.
research Towards developing an organotypic model for the preclinical study and manipulation of human hair matrix-dermal papilla interactions
The study created a new model to better understand human hair growth and health.
research Telogen Effluvium
Telogen effluvium is hair loss caused by disruption of the normal hair cycle.
research Ultrastructural characteristics of trichilemmal cysts: report of two cases
Trichilemmal cysts may form from hair follicle outer root sheath growth.
research Trichostasis Spinulosa
The document found differences in lesion distribution and microscopic features among trichostasis spinulosa and similar skin conditions.
research Quantitative Models for the Study of Hair Growth in Vivoa
The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.
research 0140 Delineating key molecular programs that induce hair-follicle-inductive dermal fibroblasts using a novel single-cell genomic approach
Wnt and SHH pathways help form hair follicles by coordinating cell processes.
