This review summarizes current knowledge on the role of the JAK/STAT signaling pathway in alopecia areata and suggests moderate efficacy of systemic inhibitors, with low adverse events but high recurrence rates.

This study investigated the use of spironolactone in patients with estrogen-dependent cancers, aiming to determine if it is linked to increased cancer recurrence risk, but results are not reported.

The authors concluded that preoperative treatment with finasteride for a month effectively reduced perioperative bleeding and shortened hospital stays in patients undergoing transurethral resection of the prostate.

This meta-analysis reported that photobiomodulation therapy may improve hair density and stimulate hair growth in patients with androgenic alopecia compared to sham treatments, but larger studies are needed to confirm these findings.

This study developed and validated tissue-specific and age prediction models using epigenetic markers, achieving up to 83.69% correct classification for tissue origin and a median absolute error of ±3.66 years for age estimation.

This study developed a prototype device that suggests potential for diagnosing changes in hair quantity, diameter, and density, though formal clinical studies are needed to confirm these findings.

This study developed new genetic prediction models for male pattern baldness with improved accuracy by utilizing a large set of markers and independent datasets, making them the most reliable available for this trait.

This study found that hair follicles and urine cell pellets from noninvasive samples may be the most promising for transcriptomic analyses due to their consistent quality and applicability to disease-relevant research.

This article argues that esthetic dermatology could benefit from a more biologically informed approach through the integration of advanced biomarkers and imaging technologies, but cautions that many tools are not yet fully validated for clinical use.

This study found that the BASP classification is an effective and easily remembered method for diagnosing and treating male and female pattern hair loss in the Indian population.

In this study, researchers in Baghdad, Iraq found that men with hair loss had higher body fat mass and haematocrit values, and lower blood pressure compared to men without hair loss, suggesting potential links between metabolic and hematologic changes and baldness.

This review explores the evaluation methods and biological parameters involved in hair growth assessment, highlighting their distinct applications and advantages, but presents no new clinical findings.

In this study, nearly 5% of anti-TNF-treated patients with IBD developed psoriasiform skin lesions, with smoking identified as a main risk factor, and ustekinumab proved highly effective in severe cases.

This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.

This study observed that while PrEP was effective among transgender women if taken, adherence was low, especially among those at higher risk.

This study found that SZ95 sebocytes and HaCaT keratinocytes exhibit distinct enzyme expressions and activities, implicating their different roles in androgen metabolism and homeostasis in vitro.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

In this study, researchers found that p75 neurotrophin receptor signaling affects apoptosis during hair follicle regression in mice, and altering its activity might help manage disorders involving early catagen entry.

This review examines the role of nuclear hormone receptors in skin wound repair processes and reports no new clinical results, highlighting the importance of their interaction with skin cells for effective healing.

This study found that daily use of 1% pyrithione zinc shampoo modestly improved hair growth over 26 weeks, although these effects were less than those of 5% minoxidil.

This review discusses the potential applications and challenges of small molecules in regenerative medicine, but it reports no new research findings.

This study found that hydroxysafflor yellow A-rich Carthamus tinctorius extract promoted hair growth and gene expression linked to hair proliferation in both cell cultures and mouse models.

This study found that etretinate treatment led to an increase in plucked telogen hair counts, suggesting a reduction in the duration of anagen as the primary cause.

This study suggests that the androgen receptor locus on the X chromosome may play a role in the pathogenesis of early-onset female pattern hair loss.

This study found that men appearing in photos after a hair transplant were perceived by observers as younger, more attractive, more successful, and more approachable compared to their pretransplant images.

This study found that recombinant hepatitis B vaccine may increase the risk of alopecia areata onset in older predisposed mice but larger trials suggest this effect might lie within normal variation.

This review detailed the types and mechanisms of injectable "skin boosters" and evaluated their effectiveness and safety for mitigating age-related skin changes, providing insight into their use in contemporary dermatological practice.

This study found that human umbilical cord blood mesenchymal stem cells promoted hair growth by advancing anagen onset and increasing hair follicle regeneration in an in vivo model.

This study found that dutasteride completely suppressed the formation of 5alpha-dihydro metabolites in cultured human skin cells, suggesting its potential use in acne and androgenetic alopecia.
