research Hormonal Regulation of Hair Follicles Exhibits a Biological Paradox
Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.
research Androgenetic Alopecia: Modeling Progression and Regrowth
AGA causes hair loss through follicle miniaturization and hair cycle changes; regrowth depends on anagen initiation in kenogen follicles.
research Short Anagen Hair With Persistent Synchronized Pattern of Scalp Hair Growth
A boy had unusual synchronized hair growth with short active growth phases, not fitting known hair disorders.
research Eyelash Preservation During Chemotherapy and Topical Prostaglandin Therapy
A woman kept her eyelashes during chemotherapy possibly because of her glaucoma eye drops.
research Quantitative Evaluation in Transverse Histological Sections of the Scalp
The study found average numbers for different types of hair follicles in the scalp and observed differences between men and women, suggesting reasons for more common hair shedding in women.
research Estetrol Prolongs Anagen in Healthy Female Scalp Hair Follicles by Positively Modulating Dermal Papilla Functions and Generation of Progenitor Stem Cells Ex Vivo
Estetrol helps keep scalp hair in the growth phase longer and improves hair follicle health by affecting the hair root and increasing stem cells.
research A Patient with Diffuse Hair Loss

Spermidine may help reduce hair loss and deserves further testing as a treatment.
research Azasteroids as Inhibitors of Testosterone 5α-Reductase in Mammalian Skin
Certain 4-azasteroids are effective at blocking the enzyme that processes testosterone in human skin and could help treat acne, excessive hair growth, and male pattern baldness.
research The Basic Science of Hair Biology
Hair disorders are caused by a complex mix of biology, genetics, hormones, and environmental factors, affecting hair growth and leading to conditions like alopecia.
research The Natural History of Androgenetic Alopecia
AGA affects many, progresses differently, and early treatment is crucial.
research Primary Scalp Alopecia: New Histopathological Tools, New Concepts, and a Practical Guide to Diagnosis
