Topical sulfonylurea may reduce excessive hair growth caused by certain medications.
research Hormones and clocks: do they disrupt the locks? Fluctuating estrogen levels during menopausal transition may influence clock genes and trigger chronic telogen effluvium
Changing estrogen levels during menopause might affect genes related to body rhythms and cause increased hair loss.
research Occult fungal infection is the underlying pathogenic cause of atherogenesis
Hidden fungal infections might cause heart disease and clogged arteries.

Melatonin and photobiomodulation are effective for treating Alopecia X in German Spitz dogs.
research 1430 Autophagy controls the protein composition of hair shafts
Autophagy is important for determining the protein makeup of hair.
research A case of unusual comedogenesis in alopecia totalis
A man with total hair loss developed blackhead-like spots on his scalp, possibly because no hair was present to help drain oils.
research Voice changes in reproductive disorders, thyroid disorders and diabetes: a review
People with reproductive, thyroid disorders, and type 2 diabetes can experience voice changes, but more research is needed to understand this better.
research 1390 Lineage-committed fibroblast populations are more efficient at regenerating hair follicles in chamber grafting assays when compared to undifferentiated embryonic fibroblasts
Differentiated fibroblasts regenerate hair follicles better than undifferentiated ones.
research 1455 Cutaneous wounds healed at the cost of overall fitness in the aged Balb/C mouse model
Older mice healed wounds better but lost more weight and might have weaker immune systems afterward.
research News updates
Early exposure to germs may protect against autoimmune diseases, lack of sex increases alcohol preference in fruit flies, a potential baldness treatment could involve blocking a specific receptor, skin memory cells help prevent re-infection, high-fat diets can affect brain cells related to weight, and the link between social status, stress, and heart disease in primates is unclear.
research 15. Hair and Nails
Women with androgenetic alopecia have fewer terminal hairs, phenol in nail surgery is safe, and a new hair transplant method is faster and less damaging.
research Faculty Opinions recommendation of Topical valproic acid increases the hair count in male patients with androgenetic alopecia: a randomized, comparative, clinical feasibility study using phototrichogram analysis.
Applying valproic acid on the scalp increased hair growth in men with hair loss.
research Post-partum pituitary insufficiency and livedo reticularis presenting a diagnostic challenge in a resource limited setting in Tanzania: a case report, clinical discussion and brief review of existing literature
Early diagnosis and hormone therapy can significantly improve outcomes for post-partum pituitary insufficiency in resource-limited settings.
research Vitamin D Receptor: New Assignments for an Already Busy Receptor
The vitamin D receptor is involved in multiple body functions beyond calcium regulation, including immune response and rapid reactions not related to gene activity.
research Molecular principles of hair follicle induction and morphogenesis
Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.
research Large-scale genome-wide meta-analysis of polycystic ovary syndrome suggests shared genetic architecture for different diagnosis criteria
The research found that PCOS has common genetic factors regardless of how it is diagnosed and is linked to metabolic and reproductive issues.
research A Mouse Model for the Basal Transcription/DNA Repair Syndrome Trichothiodystrophy
Researchers created a mouse with the same mutation as humans with trichothiodystrophy, showing similar symptoms and confirming the condition is due to defects in DNA repair and gene activity.
research Human hair melanins: what we have learned and have not learned from mouse coat color pigmentation
We know a lot about mouse hair color, but not much about human hair color differences.
research Cytokeratin 15 expression in trichoepitheliomas and a subset of basal cell carcinomas suggests they originate from hair follicle stem cells
Trichoepitheliomas and some basal cell carcinomas likely come from hair follicle stem cells.
research Cells within the bulge region of mouse hair follicle transiently proliferate during early anagen: heterogeneity and functional differences of various hair cycles
Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.
research Keratin expression in basal cell carcinomas
Basal cell carcinomas likely originate from hair follicle cells or stem cells.
research Expression of hair-related keratins in a soft epithelium: Subpopulations of human and mouse dorsal tongue keratinocytes express keratin markers for hair-, skin- and esophageal-types of differentiation
Hoxc13 is important for hair and tongue development by controlling hair keratin genes.
