research The Hair Follicle
Dogs could be good models for studying human hair growth and hair loss.
research 1390 Active hair growth is fuelled by conveyor-belt like differentiation of germinative layer cells
Hair growth is driven by cells that move and change like a conveyor belt.

Keratin 79 cells help form and regenerate hair canals.
research Androgenetic Alopecia: How It Happens
Androgenetic alopecia causes hair loss by shrinking hair follicles due to androgens, with the connection between the muscle and hair follicle determining if the loss is reversible.
research Editor's evaluation: Complementary evolution of coding and noncoding sequence underlies mammalian hairlessness
Hairlessness in mammals is due to complex genetic changes in both genes and regulatory regions.
research Corkscrew Hair: A New Dermoscopic Sign for Diagnosis of Tinea Capitis in Black Children
Corkscrew hair may be a new sign for quickly diagnosing scalp fungus in black children.
research A Prospective Longitudinal Study of Dynamic of Human Papillomavirus 6 and 11 Infection in Anogenital Hairs and Eyebrows of Male Patients with Anogenital Warts and Age-Matched Controls
HPV6/11 is often found in hair of men with anogenital warts, especially pubic hair, and can lead to recurrent warts.
research 251 Morphogenetic events in hair follicle heterotypic spheroids
The research concluded that hyaluronic acid affects the formation and growth of hair follicle-like structures in a lab setting.
research 216 Human hair follicles can “smell”: OR2AT4-mediated hair growth regulation
Human hair follicles have a scent receptor that can influence hair growth.
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
Two mouse mutants have defective hair cuticle cross-linking.
research Human Hair Keratins.
research Complementary evolution of coding and noncoding sequence underlies mammalian hairlessness
Both gene and non-gene areas of DNA evolved to make some mammals hairless.
research Curly Hair Follicle is Sculpted by a Contracted Arrector Pili Muscle. A Hypothesis with Treatment Implications
Relaxing certain muscles might straighten curly hair.
research Overexpression of Sonic Hedgehog suppresses embryonic hair follicle morphogenesis
Too much Sonic Hedgehog protein stops hair growth in embryos.
research Dermoscopic features of androgenetic alopecia and their clinical implications
Hair diameter difference, brown skin discoloration around hair follicles, and missing hair in certain areas are key signs of androgenetic alopecia (commonly known as hair loss) when viewed under a dermoscope.
research Exogen involves gradual release of the hair club fibre in the vibrissa follicle model
Hair sheds gradually from the follicle, with readiness to shed indicated by less attachment material.
research Scanning Electron Microscopic Study on Collagen Fibrils in the Mink Dermis during the Hair Cycle and Growth
Collagen fibrils in mink skin change structure during hair growth, becoming looser and thicker in the active phase.
research Outer root sheath keratinization in anagen and catagen of the mammalian hair follicle. A seventh distinct type of keratinization in the hair follicle: trichilemmal keratinization.
Trichilemmal keratinization is a unique process in hair follicles where the outer root sheath turns into keratin without a specific layer.
research The Region Coding for the Helix Termination Motif and the Adjacent Intron 6 of the Human Type I Hair Keratin Gene hHa2 Contains Three Natural, Closely Spaced Polymorphic Sites
research Mapping of cis-acting expression quantitative trait loci in human scalp hair follicles
Researchers identified genes in scalp hair follicles that may affect hair traits and hair loss.
