210-240 / 1000+ results research Maintenance of high proliferation and multipotent potential of human hair follicle-derived mesenchymal stem cells by growth factors
Growth factors help hair follicle stem cells grow and stay versatile.
research Growth of secondary hair follicles of the Cashmere goat in vitro and their response to prolactin and melatonin.
Prolactin and melatonin can stimulate hair growth in Cashmere goat hair follicles, but melatonin may reduce follicle viability over time.
research Embryonic hair follicle fate change by augmented β-catenin through Shh and Bmp signaling
β-catenin, Shh, and Bmp signaling control hair follicle development.
research Animal and in vitro Models for the Study of Hair Follicles
Understanding hair follicles through various models can help develop new treatments for hair disorders.
research Contribution of the Hair Follicular Pathway to Total Skin Permeation of Topically Applied and Exposed Chemicals
The hair follicle pathway significantly affects how easily water-loving chemicals pass through the skin.
research Fullerene nanomaterials potentiate hair growth
Fullerene nanomaterials help hair grow faster and increase hair follicles.
research Hair Regenerative Mechanisms of Red Ginseng Oil and Its Major Components in the Testosterone-Induced Delay of Anagen Entry in C57BL/6 Mice
Red ginseng oil and its components help promote hair regrowth and could treat hair loss.
research Evaluating hair growth promoting effects of candidate substance: A review of research methods
The document concludes that while lab results for hair growth promotion are promising, human trials are needed and better testing methods should be developed.
research The eyelash follicle features and anomalies: A review
Eyelashes protect the eyes, but more research is needed to understand how.
research Electron paramagnetic resonance (EPR) spectroscopy for investigating murine telogen skin after spontaneous or depilation-induced hair growth
EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.
research 5α-Reductase isozymes and aromatase mRNA levels in plucked hair from young women with female pattern hair loss
Higher enzyme levels found in women with hair loss, suggesting hormone imbalance.
research The preventive effect of vitamin D3 on radiation-induced hair toxicity in a rat model
Vitamin D3 may protect rat hair follicles from radiation damage.
research Promotion of Hair Growth by Conditioned Medium from Extracellular Matrix/Stromal Vascular Fraction Gel in C57BL/6 Mice
A substance from a specific gel helped to grow hair effectively in mice, suggesting it could potentially be used to treat hair loss in humans.
research New effects of caffeine on corticotropin‐releasing hormone (CRH)‐induced stress along the intrafollicular classical hypothalamic–pituitary–adrenal (HPA) axis (CRH‐R1/2, IP3‐R, ACTH, MC‐R2) and the neurogenic non‐HPA axis (substance P, p75NTRand TrkA) inex vivohuman male androgenetic scalp hair follicles
Caffeine may help reduce stress-induced hair loss.
research Androgens and hair: a biological paradox
Androgens can cause hair growth in some areas but hair loss on the scalp.
research Sox2 in the dermal papilla regulates hair follicle pigmentation
Sox2 controls hair color by affecting pigment production in hair follicles.
research Selected variants of the melanocortin 4 receptor gene (MC4R) do not confer susceptibility to female pattern hair loss
MC4R gene variants not linked to female hair loss.
research Intravenous Transplantation of Human Hair Follicle-Derived Mesenchymal Stem Cells Ameliorates Trabecular Bone Loss in Osteoporotic Mice
Human hair follicle stem cells can help treat bone loss in osteoporosis.
research Androgens and hair: a biological paradox with clinical consequences
Androgens can both increase body hair and cause scalp hair loss.
research Overactive Wnt5a signaling disrupts hair follicle polarity during mouse skin development
Overactive Wnt5a disrupts hair follicle orientation in mice.
research Adipose and Hair Function: An aPPARent Connection
Fat tissue and a specific protein are crucial for healthy hair growth and maintenance.
research Is paradoxical hair growth caused by low-level radiant exposure by home-use laser and intense pulsed light devices?
Home-use lasers and IPL devices are unlikely to directly cause paradoxical hair growth; it may be linked to inflammation or hormonal issues.
research Stress, Hair Growth Control, and the Neuro-Endocrine-Immune Connection
Stress may affect hair growth by influencing hair follicle development and could contribute to hair loss.
research Type 2 Diabetic Mellitus Inhibits Skin Renewal through Inhibiting WNT-Dependent Lgr5+ Hair Follicle Stem Cell Activation in C57BL/6 Mice
Type 2 diabetes slows down skin and hair renewal by blocking important stem cell activation in mice.
research The ovariectomized mouse simulates the pathophysiology of postmenopausal female pattern hair loss
Ovariectomized mice mimic postmenopausal hair loss, and estradiol helps maintain hair density.
research Diseases of the Hair and Nails
Stress, nutritional issues, and chronic diseases can cause hair loss, and nail changes may signal internal diseases; treatment focuses on the underlying cause.

The effects of estrogen on human scalp hair growth are unclear and need more research.
research The Menopausal Transition: Is the Hair Follicle “Going through Menopause”?
Menopause can cause hair thinning and texture changes due to hormonal and metabolic shifts.
research The hair growth effect of minoxidil
Minoxidil promotes hair growth by increasing blood flow and directly affecting hair follicles.
