This study found that minoxidil stimulates hair follicle growth by promoting dermal papilla cell survival and activating ERK and Akt pathways, which leads to increased proliferation and reduced cell death.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

In this study, tapering prednisone followed by 2% topical minoxidil helped limit hair loss in some patients with alopecia areata, with 30% to 47% showing over 25% hair regrowth initially.

This study found that neuroactive steroids like DHEA and pregnenolone influence cocaine-induced appetence in mice through their interaction with the ς₁ receptor, suggesting a role in individual vulnerability to addiction.

This study suggests that oxidative stress may contribute to androgenetic alopecia by inducing premature senescence and secretion of hair growth inhibitors in dermal papilla cells from balding scalp.

In this study, latanoprost significantly increased hair density in young men with mild androgenetic alopecia after 24 weeks, suggesting it may stimulate hair follicle activity and treat hair loss.

This study suggests that minoxidil activates PGHS-1, which may explain its hair growth-stimulating effects and could aid in designing more potent hair growth-promoting drugs.

This review discusses how changes in hair and skin may indicate underlying vitamin deficiencies and emphasizes the need to identify populations at risk for these deficiencies; it reports no new results.

This study found that topical formulations including extracts from Cuscuta reflexa, Citrullus colocynthis, and Eclipta alba significantly accelerated hair growth initiation and completion in rats, indicating potential benefits for treating alopecia.

The researchers reported that the petroleum ether extract of Cuscuta reflexa may promote hair growth in testosterone-induced alopecia in mice by inhibiting the enzyme 5α-reductase.

This review analyzes the traditional Iranian medicine uses of Citrullus colocynthis and compares them with modern phytotherapy findings, reporting no new clinical results but noting safety concerns and dosage considerations.

This review discusses the nutrient profile and potential health benefits of pumpkin and watermelon seeds, concluding they are underutilized and could be developed into various nutraceuticals.

This study found that polyamines enhance genome integrity by facilitating homologous recombination-mediated DNA repair, suggesting a novel role for polyamines beyond promoting cell growth and proliferation.

This study found that both 2% and 3% topical minoxidil were more effective than placebo in promoting hair growth for men with male pattern baldness over 12 months.

This study found that dimethylpabamidopropyl laurdimonium tosylate, a quaternary ammonium surfactant, adsorbs onto human scalp hair with kinetic and isotherm behaviors fitting specific models, changing hair fiber wettability from hydrophobic to hydrophilic.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

Topical minoxidil is a safe and effective treatment for hair loss caused by androgenetic alopecia.

This review discusses recent advances in the role of dermal papilla cells and adipocyte lineage cells in hair regeneration, but it reports no new clinical results.

In this in vitro study, minoxidil, diazoxide, and the novel compound NNC 55-0118 increased hair follicle growth, supporting deer follicles as a viable bioassay for ATP-sensitive potassium channel modulators.

This review discusses the current evidence and highlights gaps in research needed for the wider acceptance of low-level laser therapy as a treatment for hair loss; no new clinical results are provided.

This study found that melatonin's effect on HaCaT keratinocyte proliferation varied with concentration and incubation time, with no cytotoxic effects observed at suitable concentrations for skin treatment.

This study found that Scutellaria baicalensis extract and its main component baicalin inhibited androgen activation signaling and promoted proliferation of human dermal papilla cells, suggesting potential use in treating androgen-associated disorders.

This study found that conditioned media from epidermal progenitor cells improved skin aging signs in a clinical trial and protected fibroblasts from oxidative stress in vitro.

This literature review reported that fractional lasers, like the 1550-nm nonablative erbium-glass laser, may enhance hair regrowth by stimulating a wound healing process, but more randomized controlled trials are needed to confirm their effectiveness and optimize treatment parameters.

This research studied the effect of local testosterone propionate applications on rabbit epidermal mitotic activity but reports no new results.

In this review, the authors summarize the phytochemistry, pharmacology, and medicinal uses of Hibiscus rosa sinensis, highlighting its various benefits such as hypotensive and anti-inflammatory effects, while noting the need for more research on its specific mechanisms and potential toxicities.

This article reviews the impact of UV radiation and visible light on human hair structure and summarizes protective strategies, reporting no new clinical results.

This review discusses skin diseases in transgender patients receiving gender-affirming hormone therapy and procedures, highlighting unique conditions and the underdiagnosis that affects their quality of life and mental health.

This study found that male pattern hair loss may be associated with differences in serum levels of androstenedione, cortisol, 17 beta-estradiol, and luteinizing hormone, compared to controls.

This article reviews the challenges in treating PCOS, noting the potential benefits of insulin sensitizers on ovulatory function and pregnancy outcomes, and calls for more long-term studies on metabolic interventions.
