This review discusses recent advances in hair follicle research, highlighting therapeutic and cosmetic applications, but reports no new study results.

This study found that glycolic acid treatment reduced oxidative stress and inflammation in UV-induced skin photoaging in rats, promoting collagen recovery and reducing photoaging signs, potentially by inhibiting the PI3K/Akt and NF-κB pathways.

This review examines the mechanisms of hair follicle development and regeneration, discussing current hair loss treatments and emerging therapies like low-level laser therapy and stem cell therapy, which the authors suggest show promise in managing hair loss.

This article discusses photobiomodulation as a potential adjunct to hair follicle organoid culture for androgenic alopecia, reporting no new results and suggesting further study is needed.

This study explores how chromatin differences between dermal papilla cells and papillary fibroblasts contribute to hair follicle inductivity and investigates the regulatory changes in androgenic alopecia.

This chapter reviews differences in dermatological treatments and conditions between male and female patients, particularly noting the impacts of sex steroids on various skin processes, but presents no new clinical findings.

In this study, low-level light therapy increased the proliferation and activation of dermal papilla cells, which in turn may enhance the growth of outer root sheath keratinocytes, suggesting potential mechanisms for improving hair follicle interaction.

This study observed that in a mouse model of androgenetic alopecia, treatments with LTF, 5% minoxidil, and LTF-DPC-EXO significantly promoted hair regeneration compared to the model group, potentially through modulation of the PI3K/AKT signaling pathway.

This study suggests that a Lentinula edodes extract can improve skin barrier function, hydration, and sebum regulation, possibly by modulating vitamin D pathways, in individuals with oily and acne-prone skin.

This study reported that a spray containing Origanum marjoram essential oil significantly improved hair regrowth, dermal thickness, weight, and lymphocyte levels in rabbits with cyclophosphamide-induced alopecia, suggesting its potential as a natural alternative for hair loss treatment.

Aging skin is affected by inflammation, reduced stem cell function, and slower wound healing.

This study found that ethosomal carriers enhanced dermal and transdermal drug delivery more effectively than classic liposomes, improving delivery to deep skin layers and showing potential for treating conditions like herpes labialis and diabetes.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

Low oxygen levels can make hair-growing cells better at growing hair through a process involving reactive oxygen species.

This study found that encapsulating coffee berry extract in nanoliposomes improved its stability, reduced toxicity, and enhanced its anti-aging effects on skin elasticity and lightening more than free extract.

In this case report, estrogen substitution therapy slightly increased hair volume in a 22-year-old patient with genetic predisposition to hair loss and alopecia caused by past treatment for leukemia, but hair loss returned after stopping the therapy.

This study reports that patients with specific MFN2 mutations, including p.Arg707Trp, exhibit significant upper body fat overgrowth with suppressed leptin production, suggesting tissue-selective mitochondrial dysfunction and potential therapeutic targets.

This study found that Eucommia ulmoides bark extract shows potential antioxidant and hair follicle-support properties in vitro and in vivo, but further validation is needed to confirm these effects.

In this case report, a young Japanese man was diagnosed with scalp IgG4-related disease, which mimicked acne keloidalis nuchae but was identified by histopathology and elevated serum IgG4 levels as a systemic fibroinflammatory disorder, highlighting the importance of differential diagnosis in atypical scarring alopecia.

In this study, the researchers reported that a newly developed PYGL inhibitor, HTPI, enhanced hair growth in an ex-vivo culture by reducing oxidative damage in hDPCs and inhibiting glycogen degradation in hORSCs, showing potential as a treatment for hair loss comparable to minoxidil.

The editorial discusses the effectiveness and safety of various laser and energy-based cosmetic treatments.

This study suggests that specific mutations in the MFN2 gene, including the p.Arg707Trp allele, can result in tissue-selective mitochondrial dysfunction leading to excessive upper body fat growth and low leptin levels.

Modified Changfa Zirong Powder improves hair growth in androgenetic alopecia.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

This study found that sandalwood and rose absolute oils significantly accelerated hair regrowth in a shaved mouse model, suggesting their potential for use as hair growth stimulators.

Higher IGF-1 levels in hair follicles link to better finasteride results for hair loss.

This study found that altering levels of SFRP1 in human dermal papilla cells affects cell function and regulates Wnt/β-catenin signaling or telomerase activity, suggesting that targeting SFRP1 could potentially offer a new approach to treat hair loss diseases.

This study found that elevated STAT5 levels are linked to improved hair-inducing capabilities in human dermal papilla cells, and reducing STAT5 impairs hair follicle induction.

This study found that dexamethasone significantly reduced ERα mRNA levels and increased aromatase mRNA and activity in cultured human hair follicle dermal papilla cells, suggesting a glucocorticoid-dependent mechanism for estradiol action.

This study identified that copper depletion in dermal papilla cells reduced hair growth by boosting ROS levels, but ROS scavengers like NAC and ascorbic acid partially alleviated this effect.
