research A Mechanical Model of Overnight Hair Curling
Longer time setting curls overnight leads to better curl retention.
research Mapping Penetration of Cosmetic Compounds into Hair Fibers Using Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS)
Different oils penetrate hair differently; monounsaturated oils like olive oil penetrate better than polyunsaturated oils.
research Ex Vivo SIM-AFM Measurements Reveal the Spatial Correlation of Stiffness and Molecular Distributions in 3D Living Tissue
Collagen makes skin stiff, and preservation methods greatly increase tissue stiffness.
research Symmetry Breaking of Tissue Mechanics in Wound-Induced Hair Follicle Regeneration of Laboratory and Spiny Mice
Tissue stiffness affects hair follicle regeneration, and Twist1 is a key regulator.
research Topological Distribution of Wound Stiffness Modulates Wound-Induced Hair Follicle Neogenesis
The stiffness of a wound affects hair growth during healing, with less stiff areas growing more hair.
research Skin Aging as a Mechanical Phenomenon: The Main Weak Links
Skin aging is largely due to differences in stiffness and elasticity between skin layers, leading to wrinkles.
research Long-Acting Microneedle Formulations
Microneedles are promising for long-acting drug delivery and can improve patient compliance, but more data is needed to confirm their effectiveness.
research A Clinical Comparison of Photobiomodulation Devices for the Treatment of Alopecia in All Skin Types
More research with diverse participants is needed to determine the effectiveness of photobiomodulation devices for hair loss treatment.
research Effect of Scalp Position on Tensile Properties of Single Hair Fibers
Hair strength is similar across different scalp areas, and not affected by age, gender, or hair thickness.
research General Theory of Skin Reinforcement
Skin and its underlying fat layer act together to resist mechanical stress, and reinforcing this composite structure may help more with anti-aging than just strengthening the skin alone.
research Ruxolitinib for the Treatment of Severe Alopecia Areata
Ruxolitinib can help regrow hair in severe alopecia areata.
research Fractography of Human Hair
Moisture content significantly affects how human hair breaks.
research Antiviral Drugs Prolong Survival in Murine Recessive Dystrophic Epidermolysis Bullosa
Antiviral drugs, especially daclatasvir, may be a new treatment for a rare skin disease, improving survival and reducing symptoms in mice.
research Mechanical Forces Across Compartments Coordinate Cell Shape and Fate Transitions to Generate Tissue Architecture
Mechanical forces are crucial for shaping cells and forming tissues during development.
research Optical Coherence Tomography as an Advanced Tool in Different Applications
Optical Coherence Tomography has potential in diagnosing hair loss and monitoring blood clotting, and could be improved for deeper tissue observation and better hair loss understanding.
research Effect of Surface Treatments on the Nanomechanical Properties of Human Hair
Bleaching and combing damage hair's surface and mechanical properties.
research Involvement of Mechanical Stress in Androgenetic Alopecia
research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research Going Below and Beyond the Surface: Microneedle Structure, Materials, Drugs, Fabrication, and Applications for Wound Healing and Tissue Regeneration
Microneedles are effective for painless drug delivery and promoting wound healing and tissue regeneration.
research Tissue Engineering and Regenerative Medicine: Achievements, Future, and Sustainability in Asia
Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.
research The Role of Interface Geometry and Appendages on the Mesoscale Mechanics of the Skin
Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.
research Finasteride Treatment and Male Breast Cancer: A Register-Based Cohort Study in Four Nordic Countries
Finasteride use may increase the risk of male breast cancer.
research Postoperative Chemotherapy and Tamoxifen Compared with Tamoxifen Alone in the Treatment of Positive-Node Breast Cancer Patients Aged 50 Years and Older with Tumors Responsive to Tamoxifen: Results from the National Surgical Adjuvant Breast and Bowel Project B-16
Adding chemotherapy to tamoxifen improves survival for older breast cancer patients with positive nodes.
research Using Morphological Operators and Inpainting for Hair Removal in Dermoscopic Images
The new algorithm removes hair from skin images better than previous methods, helping diagnose melanoma.
