This study found that the dysfunction of hair follicle dermal stem cells with age contributes to hair follicle aging and hair loss in mice.

This paper reviews recent research on hair graying, suggesting that an imbalance in oxidative stress handling may affect melanocyte stem cells and melanin production with age, and calls for exploring strategies to prolong melanin production.

This study suggests that rapamycin, but not acarbose, can delay age-related loss of cochlear outer hair cells in UM-HET3 mice at doses that increase life span.

This study found that inositol hexaphosphate significantly reduced hearing threshold shifts and outer hair cell loss in various sensorineural hearing loss mouse models, suggesting potential for otoprotective use.

This study found that in SAMP8 mice, phenotypic changes in outer hair cells or the stria vascularis, possibly due to oxidative deficiencies, may predict variability in age-related hearing loss before outer hair cell loss occurs.

In this study, researchers found that cochlear hair cell function declined with age in CBA/CaJ mice starting at 10 months, before detectable hearing loss, and was marked by a decrease in cell size and BK channel currents, without effect on MET currents.

This study identified a new genetic locus, ahl4, on distal Chromosome 10 that contributes to the early-onset, severe hearing loss in A/J mice compared to B6 mice.

The study observed that in women, the number of hair follicles with an internal root sheath decreases with age in the parietal region, also hinting at a reduction in hair follicle and shaft width.

This study found that ageing in women leads to significant structural and biological changes in the scalp hair follicle environment, which may affect hair growth.

This review discusses the potential benefits of activating NRF2 for treating hair follicle disorders linked to oxidative stress and reports no new clinical results.

This review discusses the impact of age-related hair changes on perceived attractiveness and self-perception, emphasizing the need for holistic anti-aging consultations that include hair preservation strategies.

This study found that deleting the ATR gene in adult mice led to rapid onset of age-related traits such as hair graying and osteoporosis through reduced regenerative capacity.

This study found that dermal sheath stem cell characteristics are lost with aging in humans, affecting skin rejuvenation and structure, and identified specific proteins like Activin A influencing keratinocyte and fibroblast activity.

This study analyzed changes in hair diameter and density with age in Caucasian women, highlighting variations in perception of hair amount over time.

Female pattern hair loss in women can be due to hormones or aging.

This paper discusses using homoeopathic treatments combined with trichology techniques to diagnose and treat various types of hair loss, including those linked to conditions like anemia and stress, but does not report specific results.

This review discusses types of hair loss in elderly women, highlighting diagnostic challenges and treatment limitations, but does not present new research findings.

This review highlights morphological factors contributing to age-related alopecia and suggests further research to understand and potentially mitigate cellular aging processes affecting hair quality.

This study observed that among patients with PCOS, hirsutism was present in 75.63%, acne in 65%, and other skin conditions such as female pattern hair loss, acanthosis nigricans, and seborrhea in varying proportions, highlighting the dermatological impact of PCOS on patients' quality of life.

This study found that androgen inactivation pathways in scalp sebaceous glands change with age, specifically noting that AKR1C expression, including AKR1C4 previously thought liver-specific, declines with age and is sex dependent, which could impact hair follicle health during aging.

This summary reviews the conflicting reports regarding 17β‐estradiol's effects on hair follicle growth, highlighting potential estrogen receptor-mediated impacts and calling for further research.

This study found that dietary supplementation with collagen, chondroitin sulfate, low-molecular weight hyaluronic acid, Pycnogenol®, and coenzyme Q10 significantly improved skin hydration, elasticity, nail hardness, and hair condition in patients with age-related dermatological changes after 12 weeks.

This review discusses the development and potential therapeutic effects of nitroxide small molecule agents for age-related macular degeneration and cardiovascular disease, but reports no new clinical results.

This review discusses how extracellular vesicles play a dual role in age-related diseases by contributing to both disease pathogenesis and potential therapeutic strategies through the transfer of specific molecules.

This study found that perceptions of scalp micropigmentation and awareness of its side effects vary significantly by gender and age, influencing attitudes and intentions toward the procedure.

This review examines the potential of alpha-ketoglutaric acid as an anti-aging agent and for treating age-related diseases, emphasizing its metabolic, immune, and cosmetic benefits but reports no new clinical trials.

This study found that genomic instability in mouse models impair hair follicle regeneration, suggesting potential parallels in age-related hair loss in humans.

In this community-based study, the researchers found high prevalence rates of hair loss, baldness, dandruff, and greying among men aged 18-50 in Thiruvallur district, India.

In this study, researchers found that SIRT7 activates quiescent hair follicle stem cells to promote hair growth in mice by triggering the telogen-to-anagen cycle transition, with potential implications for age-related hair loss.
