This review highlights the increasing use of herbal cosmetics for maintaining healthy hair growth and preventing premature greying, influenced by rising living standards and interest in personal care.

This study found that mitochondrial dysfunction in T cells led to defective hair follicle stem cell function and premature skin aging signs in a mouse model.

This article discusses telogen effluvium, a condition where a large number of scalp hairs prematurely enter the shedding phase, and reports no new clinical results; the authors emphasize the range of potential underlying causes.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This study introduced a new classification system for distinguishing between anagen VI and early catagen stages in human hair follicle organ culture, using it to confirm eflornithine's ability to induce premature catagen.

This study found that prolactin and its receptor are expressed in the murine hair follicle epithelium, influencing hair cycle phases by down-regulating keratinocyte proliferation during anagen and inducing premature catagen.

This review discusses the relationship between aging, chronic inflammation, and immunosuppression, suggesting that these interconnected processes may contribute to tumorigenesis and premature aging, but reports no new experimental results.

This study found that the absence of Sgk3 in mice leads to impaired hair follicle maturation, characterized by reduced cell proliferation, increased apoptosis, and premature regression.

This study observed that PAI-2 is consistently expressed in differentiating cells of murine hair and nail, suggesting it may function as a marker of differentiation and possibly protect against premature cell death.

This study reviewed the role of the JAK/STAT signaling pathway in skin diseases and the potential of JAK inhibitors for treating conditions like psoriasis and atopic dermatitis. Although the findings are promising, the authors concluded it is premature to establish their place in dermatological treatments.

This article reviews the clinical aspects and potential mechanisms of chronic graft vs host disease skin manifestations, describing a novel form of premature skin aging, but presents no new research findings.

This study found that in Chinese women with PCOS, pretreatment with ethinylestradiol/cyproterone acetate was associated with a lower risk of gestational diabetes, pregnancy-induced hypertension, and premature delivery compared to those without pretreatment.

This study found that brothers of women with PCOS exhibit elevated DHEAS levels, indicating a potential familial genetic trait, but did not show increased rates of premature balding.

This study found that polymeric nanoparticles retained more minoxidil and facilitated superior drug permeation compared to lipid nanoparticles, although premature drug release affected formulation performance.

In this study, a synthetic antagonist of the p75 neurotrophin receptor was found to significantly inhibit hair follicle regression in murine skin cultures, suggesting a potential role in treating hair disorders characterized by premature catagen entry.

This study suggests that prenatal exposure to THC may negatively impact ovarian health in rats by altering miRNA expression, potentially leading to reproductive issues such as subfertility or premature reproductive senescence.

This study found that stress-induced signaling from the sympathetic nervous system in mice led to the depletion of stem cells in hair follicles, resulting in premature greying.

This article reviews the limitations in current research on photobiomodulation for hair regrowth and suggests that optimal wavelengths and dosing have not yet been identified, noting that recommending these devices may be premature.

In this study, researchers found that the KLHL24-ΔN28 protein variant disrupts hair follicle stem cells in a mouse model, leading to premature hair loss by degrading keratin 15.

In this study, the researchers described a formulation process for Ratanjot hair oil using Alkanna tinctoria roots, reporting traditional uses of the oil in preventing hair loss, baldness, premature greying, and promoting hair growth, but did not present empirical results.

This study examined the formulation of an oil derived from Alkanna tinctoria roots, traditionally used for hair health, and discusses its potential benefits for controlling hair loss, baldness, and premature greying, while promoting hair growth.

This integrative literature review revealed that chronic stress, characterized by elevated cortisol levels, negatively impacts hair follicle integrity and contributes to alopecia by promoting the premature transition from the growth phase to the resting phase of the hair cycle.

This study confirmed that methimazole use is associated with agranulocytosis, pyrexia, exposure during pregnancy, and hyperthyroidism, while also identifying new safety signals like premature birth and septic shock that require further investigation.

In this retrospective cohort study, researchers found that Taiwanese mothers with atopic dermatitis face higher risks of various pregnancy complications, such as premature labor and preeclampsia, while their children have increased risks of conditions like asthma and ADHD compared to mothers without atopic dermatitis.

In this study, telogen effluvium is characterized as a common condition in women involving sudden hair shedding due to hair follicles prematurely entering the telogen phase, with potential triggers including fever, childbirth, and stress.

This study found that women treated with GnRHa for central precocious puberty had a higher prevalence of polycystic ovary syndrome in adulthood compared to those with isolated premature thelarche.

This study found no significant differences in bone mineral density or predisposing factors across hair-loss stages in women with androgenetic alopecia, though early-onset cases may warrant investigation for premature bone loss.

This study observed that men with early-onset androgenetic alopecia had increased carotid intima-media thickness and insulin resistance, suggesting a potential link to premature atherosclerosis.

This study observed that applying a GMP-grade botanical extract to the scalp increased Bcl-2 levels, potentially preventing premature hair follicle apoptosis in chemotherapy and radiotherapy-induced alopecia.

This study suggests that in alopecia areata, an altered distribution of cytokines and growth factors in hair follicles may disrupt normal cell proliferation and induce premature hair growth phases.
