research Beyond the Epidermal-Melanin-Unit: The Human Scalp Anagen Hair Bulb Is Home to Multiple Melanocyte Subpopulations of Variable Melanogenic Capacity
The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.
research Faculty Opinions recommendation of Fgf9 from dermal γδ T cells induces hair follicle neogenesis after wounding.
A substance called FGF9 from certain immune cells can trigger new hair growth during wound healing in mice, but humans may not have the same response due to fewer of these cells.
research Generation of human-induced pluripotent stem cell-derived adherent 3-dimensional skin hair-follicle organoids
A new method was developed to efficiently grow skin hair follicles from stem cells, potentially aiding alopecia treatment.

research Generalized pustular toxic erythema: pathogenetic relationship between pustule and epidermal appendage (hair follicle or sweat duct)
Pustules in toxic erythema are linked to hair follicles or sweat ducts.
research 859 Building a functional niche for hair follicle stem cells
Deleting the CRIF1 gene in mice disrupts skin and hair formation, certain proteins affect hair growth, a new compound may improve skin and hair health, blood cell-derived stem cells can create skin-like structures, and hair follicle stem cells come from embryonic cells needing specific signals for development.

Growing hair follicles have high mitochondrial activity and ROS in specific regions, aiding hair formation.
research Environment of the Anagen Follicle
The document concludes that hair follicles have a complex environment and our understanding of it is growing, but there are limitations when applying animal study findings to humans.
research In vivo Quantification of the Effects of Radiation and Presence of Hair Follicle Pores on the Proliferation of Fibroblasts in an Acellular Human Dermis in a Dorsal Skinfold Chamber: Relevance for Tissue Reconstruction following Neoadjuvant Therapy
Hair follicle pores help cell survival and growth, even after radiation.
research A case of congenital pili multigemini
A rare, harmless hair condition was found in an infant's eyebrow, needing no treatment.
research Characterization of Hair Follicle Development in Engineered Skin Substitutes
Engineered skin substitutes can grow hair but have limitations like missing sebaceous glands and hair not breaking through the skin naturally.
research Early Dengue Virus Infection in Human Skin: A Cycle of Inflammation and Infectivity
Chicken feather gene mutation helps understand human hair disorders.
research Conditioned media obtained from human outer root sheath follicular keratinocyte culture activates signalling pathways that contribute to maintenance of hair-inducing capacity and increases trichogenicity of cultured dermal cells
The substance from human hair root cells can help maintain hair growth and make skin cells more capable of growing hair.
research T-cell “induced-self” MHC class I/peptide complexes may enable “de novo” tolerance induction to neo-antigens occurring outside of the thymus
Hair follicles may help teach the immune system to tolerate new self-antigens, but this can sometimes cause hair loss.
research Bald scalp in men with androgenetic alopecia retains hair follicle stem cells but lacks CD200-rich and CD34-positive hair follicle progenitor cells
Men with baldness due to androgenetic alopecia still have hair stem cells, but lack specific cells needed for hair growth.
research Experimental Approaches for the Reconstitution of Hair in vitro
Dermal papillae are crucial for hair growth and follicle development.
