A new mutation in the hairless gene causes hair loss and skin wrinkling in mice.
research Laser capture microdissection as a method for investigating the human hair follicle microbiome reveals region-specific differences in the bacteriome profile
Laser-capture microdissection effectively analyzes hair follicle microbiomes, revealing region-specific bacterial differences.
research Stress-induced production of chemokines by hair follicles regulates the trafficking of dendritic cells in skin
Hair follicles help attract immune cells to the skin during stress.
research Line‐field confocal optical coherence tomography: A new diagnostic method of lichen planopilaris
LC-OCT is an effective new method for diagnosing classic lichen planopilaris.
research Contrasting Localization of c-Myc with Other Myc Superfamily Transcription Factors in the Human Hair Follicle and During the Hair Growth Cycle

research Inherited Disorders of the Hair
The study concluded that genetic mutations affect human hair diseases and identified key genes and pathways involved in hair growth and cycling.
research The contribution of stem cells to epidermal and hair follicle tumours in the dog
K15 is a reliable marker for studying stem cells in dog hair follicle tumors.
research Perifollicular inflammation and follicular spongiosis in androgenetic alopecia
Hair loss in both Androgenetic Alopecia and Alopecia Areata is often accompanied by inflammation around hair follicles, but the location and severity of this inflammation varies.
research Viewpoint 4
Hidradenitis suppurativa may mainly affect vellus hair follicles, not terminal ones.
research Hair follicle targeting with curcumin nanocrystals: Influence of the formulation properties on the penetration efficacy
Curcumin nanocrystals in simple gels effectively penetrate hair follicles, but humectants can reduce this efficacy.
research Assessment of penetration of Ascorbyl Tetraisopalmitate into biological membranes by molecular dynamics
Ascorbyl Tetraisopalmitate penetrates skin better in the stratum corneum than in the infundibulum.
research Anti-Aging Medicine for Hair
Early anti-aging hair treatments should focus on anti-inflammatory agents and promoting healthy hair growth cycles.
research Involvement of Follicular Stem Cells in Forming Not Only the Follicle but Also the Epidermis
Hair follicle stem cells can form both hair follicles and skin.
research Increasing the percutaneous absorption and follicular penetration of retinal by topical application of proretinal nanoparticles
Proretinal nanoparticles improve skin absorption and reduce irritation of topical retinoids.
research SnapshotDx Quiz: August 2019
The research found that male pattern hair loss is mostly genetic and involves hair thinning due to hormonal effects and changes in gene expression.
research Matriptase Expression and Zymogen Activation in Human Pilosebaceous Unit
Matriptase is highly active in hair follicles and sebaceous glands, especially during hair growth phases.
research Basal cell carcinomas in mice arise from hair follicle stem cells and multiple epithelial progenitor populations
Basal cell carcinomas in mice can start from hair follicle stem cells and other skin cell types, depending on signaling levels.
