This review explores how hair dyes and perms can damage hair structure and notes that while some adverse outcomes like skin irritation and allergic reactions have been reported, evidence from human studies remains inconsistent regarding potential risks, including cancer.

In this review, researchers summarize key factors in constructing skin organoids, including cell source and assembly methods, and emphasize advances such as air-liquid interface culture for improving tissue development, aiming to guide standardized protocols and future clinical applications.

In this study, researchers found that patients with non-scar alopecia exhibited thinner hair sacs and root sheaths compared to a control group, with significant thinning observed in cases of alopecia areata.

In this study, an 18-year-old boy with alopecia areata successfully experienced normal and healthy hair regrowth after 4 months using microneedling with cupping, alongside internal herbal medication and topical oil application, as a cost-effective and less invasive alternative to high-cost hair treatments and transplantation.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

This review discusses advancements in artificial skin for wound treatment and reports no new clinical findings; the authors highlight the potential of new biomaterials to enhance future skin replacement therapies.

This study developed and validated a computational model to optimize skin precooling methods for minimizing thermal damage during laser procedures.

In this study, researchers found that trichothiodystrophy hair brittleness is linked to abnormalities in sulfur content and structural organization, making it prone to breakage.

The study concluded that fatty acid transport protein 4 in epidermal keratinocytes is crucial for maintaining normal skin structure, as its deficiency led to hyperkeratosis and epidermal barrier disruption in mice.

This study identified the AtPRPL1 gene in Arabidopsis thaliana as being involved in cell elongation processes, despite unclear changes in cell wall composition from its altered expression.

This study found that knocking out the transactivation domain of Miz1 in mouse keratinocytes disrupted hair follicle orientation, caused irregular pigmentation, and increased keratinocyte proliferation, indicating Miz1's role in hair follicle development and morphogenesis.

This study found that human outer root sheath cells express VEGF receptor-2, and exogenous VEGF165 significantly stimulates their proliferation through activation of the ERK signaling pathway.

This study found that in male androgenic alopecia, the androgen receptor coactivator ARA70/ELE1 exhibits differential expression patterns, suggesting its involvement in the condition.

This study reports that transgene insertion in homozygous transgenic mice causes irreversible hair loss and impaired immune function, linked to interruption of the hairless locus on Chromosome 14.

This study found that targeting SV40 T antigen expression to hair follicles in transgenic mice caused abnormal hair structure and hair loss, but did not lead to cell immortalization or tumor formation in follicles.

This review discusses various follicular unit excision methods, punch designs, and motorized devices, highlighting their roles in reducing hair follicle transection rates and optimizing graft harvesting for individual patient characteristics.

This study investigated various proteins as eco-friendly hair perming agents for Asian hair and found that bovine serum albumin and keratin achieved perming results comparable to commercial products, while also increasing hair moisture, indicating a protective effect during heat styling.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.

This review explores the immunological aspects of epidermal differentiation in loricrin knockout mice, offering insights into keratinization and potential intrinsic factors affecting immune function, but provides no new clinical findings.

This study synthesized and characterized new 2-hydroxypyrrolidine/piperidine derivatives using FeCl₃·6H₂O as a catalyst, but it reports no biological or clinical results.

This study identified 8-hydroxy germacrene B from Curcuma aeruginosa as a highly potent in-vitro 5-alpha reductase inhibitor with significant anti-androgenic activity, while exhibiting mild cytotoxicity on prostate cancer cells without affecting human dermal papilla cells at tested concentrations.

The researchers reported that PEG-FGF2 conjugates, particularly Compound 6, significantly enhanced stability, proliferation, migration, and wound healing activity compared to native FGF2, despite some reduction in bioactivity near crucial binding domains.

This review discusses how ionizing radiation causes skin damage by inducing cellular senescence in keratinocytes, which secrete inflammatory mediators, recruiting immune cells and exacerbating inflammation, impacting the skin barrier function and healing.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This study introduces "Homeodynamic Rejuvenation" as a method to restore the skin's resilience by enhancing its ability to detect and recover from stress, focusing on five core biological processes critical for maintaining skin function and health amidst environmental and metabolic challenges.

This study found that both dark and white dromedary camels exhibited high medullation in hair fibers, suggesting adaptations for insulation and heat dissipation in hot desert environments.

This study found that scalp cooling resulted in visible hair retention in 53% of breast cancer patients undergoing Epirubicin/Cyclophosphamide and Paclitaxel treatment, with factors like hair bulb diameter, shaft diameter, and anagen rate significantly predicting outcomes.

This study found that isolated hair follicle outer root sheaths from mice can regenerate new dermal papillary structures in vitro, with stem cells and neutrophils playing key roles in the regeneration process.

This thesis explores how optical coherence tomography and advanced imaging methods may address clinical needs in fields like interventional pulmonology and dermatology, highlighting their potential for disease assessment and staging.

This research observed that chronological age, rather than hearing loss, primarily affects the auditory cortex in aging, and found that brain aging in PolG mice mirrored that of wild-type counterparts, suggesting differential tissue sensitivity to mitochondrial dysfunction.
