research The Effect of 5α-Reductase Inhibition with Dutasteride and Finasteride on Semen Parameters and Serum Hormones in Healthy Men
Dutasteride and finasteride may reduce sperm count and volume but don't affect movement or shape; effects are reversible after stopping.
research ELECTRON MICROSCOPE STUDIES OF HAIR AND WOOL
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Hair Follicle Dermal Stem Cells Regenerate the Dermal Sheath, Repopulate the Dermal Papilla, and Modulate Hair Type
Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.
research Fibrous scaffolds potentiate the paracrine function of mesenchymal stem cells: A new dimension in cell-material interaction
Special fiber materials boost the healing properties of certain stem cells.
research Cutaneous Scarring: Basic Science, Current Treatments, and Future Directions
New effective scar treatments are urgently needed due to the current options' limited success.
research Cerebellar Medulloblastoma: Treatment by Irradiation of the Whole Central Nervous System
Radiation therapy with a higher dose for the brain improves survival in cerebellar medulloblastoma.
research Skin CD4+ memory T cells exhibit combined cluster-mediated retention and equilibration with the circulation
Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.
research Theoretical considerations in laser hair removal
Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.
research Global Adiposity Rather Than Abnormal Regional Fat Distribution Characterizes Women with Polycystic Ovary Syndrome
Women with PCOS have overall higher body fat, not abnormal fat placement, and more insulin resistance.
research Do men’s faces really signal heritable immunocompetence?
Masculine facial features may not reliably indicate heritable health, and more research is needed.
research Phase I Study of the Hedgehog Pathway Inhibitor IPI-926 in Adult Patients with Solid Tumors
The drug IPI-926 is safe at 160 mg daily and may help treat certain tumors, especially basal cell carcinoma.
research A randomized evaluator blinded study of effect of microneedling in androgenetic alopecia: A pilot study
research Hair Growth Cycle Affects Hair Follicle Destruction by Ruby Laser Pulses
Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.
research Baiting Proteins with C60
C60 fullerenes can alter protein function and may help develop new disease inhibitors.
research Synthesis and Structure–Activity Relationships of the First Ferrocenyl-Aryl-Hydantoin Derivatives of the Nonsteroidal Antiandrogen Nilutamide
Scientists made the first metal-based compounds from a nonsteroidal antiandrogen drug, which showed potential in fighting both hormone-dependent and independent prostate cancer cells.
research Nanozymes expanding the boundaries of biocatalysis
Nanozymes greatly improve biocatalysis by being stable, efficient, and versatile.
research Hardwiring Stem Cell Communication through Tissue Structure
The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.
research Procyanidin Oligomers Selectively and Intensively Promote Proliferation of Mouse Hair Epithelial Cells In Vitro and Activate Hair Follicle Growth In Vivo11The authors disclosed conflict of interest.
Procyanidin compounds from grape seeds were found to significantly increase mouse hair growth.
research The Effect of 5α-Reductase Inhibition With Dutasteride and Finasteride on Bone Mineral Density, Serum Lipoproteins, Hemoglobin, Prostate Specific Antigen and Sexual Function in Healthy Young Men
Dutasteride and finasteride do not significantly affect bone density, blood fats, or blood production, but slightly lower PSA levels and minimally impact sexual function in healthy young men.
research Nanocarriers for optimizing the balance between interfollicular permeation and follicular uptake of topically applied clobetasol to minimize adverse effects
Nanocapsules can improve clobetasol delivery to hair follicles, reducing side effects.
research Red ginseng monograph
Red ginseng may improve immunity, fatigue, memory, blood circulation, and menopausal symptoms, and is generally safe to consume.
research The Hair Follicle: A Paradoxical Androgen Target Organ
Androgens can both promote and prevent hair growth due to differences in gene expression in hair follicles.
research Prolactin—a novel neuroendocrine regulator of human keratin expressionin situ
Prolactin affects the production of different keratins in human hair, which could lead to new treatments for skin and hair disorders.
research Hair follicle neogenesis induced by cultured human scalp dermal papilla cells
Scientists found a way to grow human hair cells in a lab that can create new hair when transplanted.
research The control of hair growth: An overview
Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.
research Oxidative Damage Control in a Human (Mini-) Organ: Nrf2 Activation Protects against Oxidative Stress-Induced Hair Growth Inhibition
Activating Nrf2 protects human hair follicles from oxidative stress and helps prevent hair growth inhibition.
