This study found that repeated microneedle stimulation in mice promoted hair growth and increased the expression of hair-growth-related genes, suggesting potential therapeutic uses for alopecia.

This study found that palmitoylethanolamide may stimulate allopregnanolone synthesis and reduce oxidative stress in astrocytes through PPAR-α activation, suggesting a neuroprotective role.

This study found that diagnosing nonclassic congenital adrenal hyperplasia in women based solely on serum 17OHP measurements can lead to false positives, suggesting the need for urinary steroid profiles and genetic testing for confirmation.

This study found that macrophage-stimulating protein (MSP) enhanced hair growth in both human hair follicles cultured in vitro and in mice through the promotion of anagen phase induction.

In this study, researchers found that petroleum ether extract of Eclipta alba significantly stimulated follicular keratinocyte proliferation and reduced TGF-β1 expression in nude mice, suggesting potential use for certain types of alopecia.

This study concluded that neither basal nor ACTH-stimulated 17-OHP concentrations effectively indicate carrier status for 21-hydroxylase deficiency among Slovenian hyperandrogenic women, recommending molecular analysis of the CYP21 gene for reliable screening.

This study found that stimulation with certain neurotransmitters and hormones suggests the involvement of 5α-reduced neurosteroids in glial cell differentiation in rat C6 glioma cells.

Higher thyroid hormone levels may be linked to certain types of polycystic ovary syndrome.

This study found that testosterone propionate increased hair mass in female hamsters' flank organs, while cyproterone acetate applied topically reduced androgen-stimulated hair in a dose-dependent manner.

This study found that centrifugally spun scaffolds with higher concentrations of platelet-derived bioactive molecules enhanced melanocyte metabolic activity and proliferation, suggesting potential for improving vitiligo treatment.

This study found that while both natural and bioengineered salivary glands showed similar protein concentrations in response to taste stimulation, their protein compositions and amylase concentrations differed, which may affect nerve signal balance.

This study demonstrated that electrical stimulation via a polypyrrole-modified electrode enhanced trichogenic gene expression in human dermal papilla cells, leading to increased hair growth in a mouse model.

This study found that activating TRPV4 in the skin of mice induced hair follicle regeneration by promoting anagen transition, suggesting potential treatment strategies for hair loss.

This study found that the FSHR Ser680Asn (rs6166) gene polymorphism is associated with an increased risk of PCOS in the examined population and could serve as a molecular biomarker for identifying risk.

This review suggests that dihydrotestosterone pretreatment may improve cosmetic outcomes in hypospadias repair, but more randomized trials are needed to determine its effectiveness due to currently limited evidence.

This study reported that novel adipose slurry injections improved rhytides and dermis density in patients receiving facial wrinkle treatments based on evaluations at multiple follow-up intervals.

Low-dose pulsed electric fields in a rat model shifted hair follicles from resting to active growth, with voltage as the most influential factor.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

In this study, researchers demonstrated that human hair follicle outer root sheath cells release ATP, serotonin, and histamine in response to mechanical stimulation, which subsequently activates surrounding sensory neurons.

This study found that stimulating dermal papilla cells with specific adipo-osteogenic factors and growth factors helped maintain their viability and restored their hair-forming activity in vitro.

In this study, researchers observed that in nude mice, exogenous stimulations lengthened the hair-existing phase and shortened the no-hair phase, with minoxidil influencing male and female mice differently.

This study observed that the Pilogics Hairegen device increased total hair count by 23.2% and terminal hair count by 21.1% in 289 patients with androgenetic alopecia after approximately 20 weeks of use, with no adverse effects reported.

In this study, topical dehydroepiandrosterone (DHEA) doubled sebum production in women without systemic side effects, suggesting it may be a safe treatment for reduced sebum output related to menopause.

This narrative review from the authors discusses mechanical scalp stimulation as a potential treatment for androgenetic alopecia, suggesting it has a biologically plausible mechanism but immature clinical evidence; marketing of these devices currently outpaces their supporting data, indicating a need for better-controlled trials.

This narrative review suggests that while mechanical scalp stimulation has a plausible mechanism for aiding androgenetic alopecia, its clinical evidence is insufficient, and the marketing of stimulation devices currently outpaces their efficacy data.

This study reported that a newly designed multifunctional conductive hydrogel, PrM, combined with electrical stimulation significantly accelerated wound healing, achieving 95.9% healing in a mouse model on day 10, by enhancing regenerative processes and downregulating TNF-α signaling under electrical treatment.

This narrative review concluded that facial aging involves complex anatomical changes that require multimodal rejuvenation approaches, integrating fillers, collagen stimulators, botulinum toxin, and energy-based devices for effective results, while emphasizing the need for scientific evidence and patient safety in aesthetic treatments.

In this study, subthermal RF-CRET currents were found to alter key molecular mechanisms in dermal papilla cells, promoting proliferation and survival while enhancing markers associated with hair growth and maintenance, suggesting potential benefits for hair regeneration.

The correction does not change the conclusion that 2-deoxy-D-ribose helps hair regrowth.

In this study, researchers found that both oral and percutaneous applications of melatonin and lyotritone in laboratory rats enhanced hair quality and growth rate compared to a control group, which showed slower hair growth and lower hair quality.
