research Minoxidil: mechanisms of action on hair growth
Minoxidil boosts hair growth by opening potassium channels and increasing cell activity.
research On the etiology of vitiligo and gray hair
Melanocytes are destroyed by factors needed for melanin production, causing vitiligo and gray hair.
research Towards a “free radical theory of graying”: melanocyte apoptosis in the aging human hair follicle is an indicator of oxidative stress induced tissue damage
Oxidative stress causes hair to gray by damaging and killing pigment cells.
research Lactate dehydrogenase activity drives hair follicle stem cell activation
Lactate production is important for activating hair growth stem cells.
research Melanogenesis During the Anagen-Catagen-Telogen Transformation of the Murine Hair Cycle
Hair stops producing melanin as it transitions from the growth phase to the resting phase.
research Hair cycle and hair pigmentation: dynamic interactions and changes associated with aging
As people age, their hair follicles produce less pigment, leading to gray and white hair, due to factors like reduced enzyme activity and damage to melanocyte DNA.
research Nanoparticles for Topical Application in the Treatment of Skin Dysfunctions—An Overview of Dermo-Cosmetic and Dermatological Products
Nanoparticles improve skin treatment but need more research on safety and effectiveness.
research CHRONIC TREATMENT WITH FINASTERIDE DAILY DOES NOT AFFECT SPERMATOGENESIS OR SEMEN PRODUCTION IN YOUNG MEN
Finasteride doesn't harm male fertility or sperm quality, but may slightly reduce ejaculate volume.
research Targeting Wnt/β-Catenin Pathway for Developing Therapies for Hair Loss
Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.
research Melanocyte Subpopulation Turnover During the Human Hair Cycle: An Immunohistochemical Study
Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.
research Aging of the hair follicle pigmentation system
Hair grays due to oxidative stress and fewer functioning melanocytes.
research An overview of chemical straightening of human hair: technical aspects, potential risks to hair fibre and health and legal issues
Chemical hair straightening can damage hair and health, needing safer alternatives and stricter regulations.
research Topical Application of a Protein Kinase C Inhibitor Reduces Skin and Hair Pigmentation
Applying a specific inhibitor lightens skin and hair color.
research Hair regrowth in alopecia areata patients following Stem Cell Educator therapy
Stem Cell Educator therapy helps regrow hair and improve life quality in alopecia areata patients.
research Endogenous retinoids in the hair follicle and sebaceous gland
Maintaining the right amount of retinoic acid is crucial for healthy hair and skin.
research Controllable Production of Transplantable Adult Human High-Passage Dermal Papilla Spheroids Using 3D Matrigel Culture
Researchers created hair-inducing human cell clusters using a 3D culture method.
research Normal Fur Development and Sebum Production Depends on Fatty Acid 2-Hydroxylase Expression in Sebaceous Glands
FA2H is essential for normal fur and sebum production in mice.
research Deciphering the functions of the hair follicle infundibulum in skin physiology and disease
The hair follicle infundibulum plays a key role in skin health and disease, and understanding it better could lead to new skin disease treatments.
research Hair Follicular Expression and Function of Group X Secreted Phospholipase A2 in Mouse Skin
sPLA2-X is crucial for normal hair growth and follicle health.
research STIMULATING EFFECT OF ADRENALECTOMY ON HAIR GROWTH AND MELANIN DEPOSITION IN BLACK RATS FED DIETS ADEQUATE AND DEFICIENT IN THE FILTRATE FACTORS OF VITAMIN B1
Adrenalectomy boosts hair growth and melanin in black rats, even with vitamin B¹ deficiency.
research Oral zinc sulphate causes murine hair hypopigmentation and is a potent inhibitor of eumelanogenesisin vivo
Oral zinc sulphate reduces dark hair color in mice.
research Ancient Genomes Reveal the Evolutionary History and Origin of Cashmere-Producing Goats in China
Ancient Chinese goats evolved cashmere-producing traits due to selective breeding, particularly in genes affecting hair growth.
research Three Streams for the Mechanism of Hair Graying
Hair graying may be caused by stem cell depletion from stress or melanocyte damage.
research PPAR‐γ signalling as a key mediator of human hair follicle physiology and pathology
PPAR-γ is important for healthy hair and its problems, and more research on PPAR-γ treatments is needed.
research Different localizations of drugs simultaneously administered in a strand of hair by micro‐segmental analysis
Drugs localize differently in hair strands based on their properties.
research Age-Related Hair Pigment Loss
Graying hair happens due to aging and might be delayed by new treatments.
research The Microanatomy, Cell Replication, and Keratin Gene Expression of Hair Follicles during a Photoperiod-lnduced Growth Cycle in Sheep
Changing light periods synchronized wool growth cycles in sheep.
research Hair loss and hyperprolactinemia in women
