In this study, topical minoxidil was reported to increase fenestration in follicular capillary walls around anagen hair bulbs in male rats.

This study developed a sensitive method for assessing hair keratin stretch elasticity modulus, suggesting potential applications in forensic medicine.

This study found that applying a cosmetic active ingredient improved the Young's modulus of chemically damaged human hair fibers, suggesting enhanced mechanical properties compared to untreated fibers.

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.

This study reported that a new two-point bending stiffness method effectively correlated with sensory assessments for hair styling gels but not for hair styling sprays, likely due to differences in polymer/hair composites.

This study found that treatments like abrasion, bleaching, and CETAB application affect hair fiber shear modulus differently, with moisture levels notably impacting bleached fibers more than untreated ones.

This study by Bansaccal et al. found that skin with higher levels of type I collagen density and elasticity in the dermis can inhibit basal cell carcinoma development and spread by acting as a natural barrier against cell reprogramming in mice.

This study found that human hair follicle dermal papilla cells and keratinocytes self-assembled differently in 3D spheroid co-cultures, providing insights into cell distribution and organogenesis during skin regeneration.

This study investigated various animal tissues from adult mice and embryonic chicks, finding that tissue stiffness follows a sub-linear power law relationship with Collagen-I levels, consistent with cellularized collagen gels but not acellular ones.

This abstract discusses the importance of thoroughly evaluating donor area characteristics like hair density and scalp elasticity in planning hair transplantation, but it reports no new research findings.

A skin condition called pyodermatitis vegetans was found in a patient with multiple myeloma for the first time.

This study developed a model showing that keratin elasticity in skin may be influenced by electrostatic and bridging interactions between keratin filaments, contingent on the balance of charges in the surrounding medium.

This study observed that donor strip scar width after hair transplantation was correlated with preoperative scalp laxity and elasticity but not with glidability.

This study reported that gels containing methyl cellulose exhibited the highest consistency factor and optimal homogeneity compared to those made with hydroxypropyl cellulose or its combination with pullulan, indicating the significant impact of gelling agents on gel properties.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

Most bald men don't protect their scalp from the sun, and doctors should encourage prevention.

This study explores torsional measurements of single hair fibers to differentiate the effects of cosmetic treatments on hair structure, highlighting their potential to reveal shear stiffness changes related to cuticle damage.

This study developed a multiscale model to understand human hair fiber mechanics and found that the yield stress decreases linearly with temperature, supported by both simulations and experimental stretching of hair fibers.

This mini-review highlights emerging themes on how tissue stiffness, a fundamental material property, influences morphogenetic processes in living organisms, an area gaining increased attention alongside the role of mechanical forces in shaping cell behavior.

This review explores fibroblast heterogeneity in the mammalian dermis and suggests potential therapeutic applications by targeting fibroblast subtypes, but reports no new experimental results.

This study found that penetration enhancer-containing vesicles significantly improved minoxidil delivery to the skin compared to traditional liposomes and penetration enhancer-containing ethanolic solutions, with deformability linked to enhanced deposition.

This review discusses the role of nutraceuticals in combating skin aging but reports no new clinical results, focusing on their mechanisms of action and potential effectiveness for dermatologists.

This study found that Transcutol-containing vesicles improved the delivery of minoxidil to deeper skin layers in vitro but did not facilitate its permeation through the skin.

This study found that improved outcomes in scalp surgery were achieved by utilizing knowledge of the surgical anatomy of the scalp to avoid complications like unsightly scars and distorted hair patterns.

This review outlines the processes and potential of stem cells in regenerating skin, hair, and other tissues but presents no new experimental findings.

This study found that seven cases of cicatricial alopecia initially diagnosed as discoid lupus erythematosus were more consistent with lichen planopilaris based on histopathology.

This review derived guidelines for scalp surgery suggesting improved outcomes when avoiding neurovascular structures, preserving tissue integrity, and maintaining hair direction, but it reports no new clinical results.

This abstract provides website information and publication navigation for JAMA Dermatology, but it includes no research results or study findings.
