New genetic locations explain much of hair color variation in Europeans.
research Delivery and targeting of nanoparticles into hair follicles
Nanoparticles can improve skin treatments by better targeting hair follicles, but more research is needed for advancement.
research Hair follicles contribute significantly to penetration through human skin only at times soon after application as a solvent deposited solid in man
Hair follicles greatly increase caffeine absorption through the skin shortly after it's applied.
research Epidermal Growth Factor as a Biologic Switch in Hair Growth Cycle
EGF controls hair growth by regulating hair follicles' growth phases.
research Effects of EGF on the Morphology and Patterns of DNA Synthesis in Isolated Human Hair Follicles
EGF makes hair follicles grow longer but stops hair production.
research Ozone interactions with human hair: Ozone uptake rates and product formation
Ozone reacts more with unwashed hair, producing compounds due to scalp oils, which could lower ozone exposure but increase exposure to reaction products.
research K25 (K25irs1), K26 (K25irs2), K27 (K25irs3), and K28 (K25irs4) Represent the Type I Inner Root Sheath Keratins of the Human Hair Follicle
K25, K27, and K28 are found in all inner root sheath layers of hair, while K26 is only in the cuticle.
research Cloning of wrinkle-free, a previously uncharacterized mouse mutation, reveals crucial roles for fatty acid transport protein 4 in skin and hair development
Fatty acid transport protein 4 is essential for skin and hair development.
research Cyclic hair-loss and regrowth in transgenic mice overexpressing an intermediate filament gene.
Mice with extra sheep genes had hair that fell out and regrew in cycles.
research Self-organization process in newborn skin organoid formation inspires strategy to restore hair regeneration of adult cells
Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.
research A Meeting of Two Chronobiological Systems: Circadian Proteins Period1 and BMAL1 Modulate the Human Hair Cycle Clock
BMAL1 and Period1 genes can influence human hair growth.
research Efficacy, safety, and tolerability of dutasteride 0.5 mg once daily in male patients with male pattern hair loss: A randomized, double-blind, placebo-controlled, phase III study
Dutasteride 0.5 mg daily improves hair growth safely in men with hair loss.
research Bone morphogenetic protein signaling regulates the size of hair follicles and modulates the expression of cell cycle-associated genes
BMP signaling controls hair follicle size and cell growth by affecting cell cycle genes.
research Gene expression profiling gets to the root of human hair follicle stem cells
Human hair follicle stem cells can be isolated using specific markers for potential therapeutic use.
research Towards Dissecting the Pathogenesis of Retinoid-Induced Hair Loss: All-Trans Retinoic Acid Induces Premature Hair Follicle Regression (Catagen) by Upregulation of Transforming Growth Factor-β2 in the Dermal Papilla
All-trans retinoic acid causes hair loss by increasing TGF-β2 in hair follicle cells.
research Hair Cycle Control by Estrogens: Catagen Induction via Estrogen Receptor (ER)-α Is Checked by ERβ Signaling
Estrogen receptors affect hair growth, with ER beta slowing down the hair cycle changes caused by ER alpha.

Finasteride improves hair loss in women with hyperandrogenism.
research Topical application of Polygonum multiflorum extract induces hair growth of resting hair follicles through upregulating Shh and β-catenin expression in C57BL/6 mice
Polygonum multiflorum extract helps grow hair by activating certain hair growth signals in mice.
research Order from disorder: Self-organization in mammalian hair patterning
Hair patterns in mice are controlled by both a global system dependent on Fz6 and a local self-organizing system.
research Prolactin and Its Receptor Are Expressed in Murine Hair Follicle Epithelium, Show Hair Cycle-Dependent Expression, and Induce Catagen
Prolactin affects hair growth cycles and can cause early hair follicle regression.
