research Keep your hair on
Immune cells called Treg cells are essential for hair growth and regeneration.
research Cross-linked features of mouse pelage hair resistant to detergent extraction
Some mutant mice have hair with abnormal cross-linking, mainly in the cuticle, not affecting other hair parts.
research Hair for brain trade-off, a metabolic bypass for encephalization
Human hair loss may have evolved to help increase brain size.
research Novel aspects of age-protection by spermidine supplementation are associated with preserved telomere length
Spermidine helps protect against aging by preserving telomere length.
research Hair growth induction by the tellurium immunomodulator AS101: association with delayed terminal differentiation of follicular keratinocytes and ras‐dependent up‐regulation of KGF expression
The substance AS101 can help hair grow by slowing down hair cell aging and boosting a hair growth protein.

research Faculty Opinions recommendation of De novo production of dermal papilla cells during the anagen phase of the hair cycle.
New cells join the hair's dermal papilla during the growth phase, possibly affecting hair thickness.
research Progeroide Syndrome
Genetic mutations affecting DNA repair cause early aging symptoms in progeroid syndromes.
research Coexistence of Quiescent and Active Adult Stem Cells in Mammals
Active and quiescent stem cells work together in mammals to maintain and repair tissues.
research Human dermal Vδ1 + T-cells recognize “stressed” HFs and may induce alopecia areata
Certain immune cells may cause hair loss by reacting to stressed hair follicles.
research Single‐cell RNA sequencing highlights the role of proinflammatory fibroblasts, vascular endothelial cells, and immune cells in the keloid immune microenvironment
Proinflammatory fibroblasts and vascular endothelial cells are key in keloid development.
research Novel small‐insertion mutation in the LIPH gene in a patient with autosomal recessive woolly hair/hypotrichosis

research Peer Review #2 of "Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis (v0.1)"
The research found that people's hair proteins vary, especially by ethnicity and body part, which could help identify individuals in forensic science.
research Identification of reptilian genes encoding hair keratin-like proteins suggests a new scenario for the evolutionary origin of hair
Reptiles have genes similar to hair proteins, suggesting hair's genetic origins predate mammals.
research LB1777 A novel ex vivo model of human hair follicle immune privilege collapse reveals the potential of farudodstat, a DHODH inhibitor, as a therapeutic for alopecia areata treatment
Farudodstat may help treat alopecia areata by protecting hair follicles.
research Impact of Preservation Solutions on the Trichogenicity of Hair Micrografts Ascertained by Dermal Papilla Gene Expression

research An investigation of apoptosis in androgenetic alopecia.
Hair loss in men might be linked to programmed cell death.
research KLHL24-Mediated Hair Follicle Stem Cells Structural Disruption Causes Alopecia
A faulty KLHL24 gene leads to hair loss by damaging hair follicle stem cells.
research Genome-wide association study in alopecia areata implicates both innate and adaptive immunity
Alopecia areata involves both innate and adaptive immunity, with specific genes linked to the disease.
research 1378 A multi-omics approach to identifying factors involved in hair follicle growth and development
The research found that certain factors in hair follicle cells control hair growth and development, and these could be used to create new treatments for hair loss.
research Lineage Commitment of Dermal Fibroblast Progenitors is Mediated by Chromatin De-repression
Skin cell types develop when specific genes are turned on by removing certain chemical tags from DNA.
