This study found that cross beam laser is a reliable tool for assessing scalp laxity in hair restoration surgery, with results comparable to the Mayer elasticity scale.

Laser Lax is a new tool that measures scalp looseness accurately and comfortably.

This study found that HairTime, a novel non-invasive assay using hair samples, accurately estimates chronotype and reveals its plasticity influenced by work schedules and lifestyle factors.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

In this review, several studies on Astragalus species, particularly Astragalus membranaceus, highlight their skin rejuvenating, photoprotective, antimicrobial, and wound-healing properties, though the authors note limitations due to reliance on non-human studies and short trial durations.

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

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

This study found that testosterone and dihydrotestosterone are crucial for synaptic transmission and spine density in male hippocampal neurons, suggesting sex-specific effects of neurosteroids on brain development.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This review discusses environmental reprogramming and the plasticity of epithelial cells, emphasizing their potential for new cell therapy approaches; it reports no new experimental results.

This review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing new experimental results.

In this multicenter study, adipose-derived stem cell-enriched fat grafting achieved higher satisfaction and better clinical outcomes compared to platelet-rich plasma and hyaluronic acid filler in aesthetic interventions.

This treatise provides guidelines and suggestions for the safe practice of follicular unit transplantation but reports no new clinical results.

This review indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.

This systematic review suggests that turmeric and curcumin products, both oral and topical, may offer therapeutic benefits for various skin conditions, though further research is necessary to evaluate efficacy more thoroughly.

This review examines non-invasive methods for diagnosing inflammatory skin diseases like lupus erythematosus and psoriatic inflammation using samples from plucked hair and skin tape-strips, but no new clinical results are presented.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.

This review highlights that castor oil has potential dermatological uses, including enhancing hair luster, reducing hyperpigmentation, and improving skin hydration and elasticity, although rare side effects like contact dermatitis occur, necessitating further research to confirm its effectiveness in these applications.

This study observed that photobiomodulation therapy may contribute to hair growth stability or improvement in individuals with darker skin types, without reported adverse events, though its findings are limited by a small sample size.

This study found that sericin dressing containing collagen hydrolysate significantly reduced wound healing time and improved scar quality compared to commercial dressing in split-thickness skin graft donor sites.

This study reported that bioactive peptides from skin collagen, obtained through selective hydrolysis, improve skin collagen synthesis and remodeling, while inhibiting its breakdown by metalloproteinases, showing benefits such as enhanced skin hydration, elasticity, healing, and hair restoration, without associated adverse effects.

This review discusses advances in using molecular tools from skin biology to manipulate adult stem cells for regenerative medicine and reports no new clinical results.

This review discusses hair transplant techniques for female pattern hair loss and reports no new clinical results; it highlights the benefits of transplants combined with various treatments for improved hair density and styling options.

In this study, researchers observed that Malassezia species show different lipid metabolism and growth patterns depending on pH, with slightly acidic conditions promoting beneficial lipid bio-conversion for skin health, while neutral pH resulted in lower growth and lipid content, potentially negatively impacting the skin.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This review discusses current concepts in wound repair and suggests that these evolving paradigms might also explain regenerative processes in various organ systems, but it reports no new research findings.

This study introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.

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.

This study found that fibronectin nanofiber dressings, made using rotary jet spinning, accelerated wound healing and improved tissue restoration in a full-thickness wound mouse model.
