This review discusses the cosmetic use and safety of Hypericum Perforatum Extract and Oil, finding that current data are insufficient to support their safety in formulations due to a lack of comprehensive testing.

This review found no evidence that DHEA improves quality of life or decreases menopausal symptoms in peri- and postmenopausal women, but it may slightly enhance sexual function compared to placebo.

This study found that minoxidil prevents long-term serotonergic toxicity induced by MDMA in rats, primarily by opening mitochondrial KATP channels and involving Akt and MAP kinases in its neuroprotective mechanism.

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 Rumex japonicus extract may help reduce symptoms of atopic dermatitis by inhibiting inflammatory responses in both cell cultures and a mouse model.

In this study, PTH-CBD effectively prevented and partially reversed chemotherapy-induced alopecia in mice, with pretreatment offering a better cosmetic outcome compared to therapeutic administration after hair loss onset.

This study found that inhibiting EGFR signaling in mice can prevent alopecia caused by cyclophosphamide treatment, highlighting its potential role in managing chemotherapy-induced hair loss.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This study reports that the novel small molecule IM176OUT05, by modifying stem cell metabolism, promoted hair regrowth and increased hair follicle numbers in mice.

In this narrative review, the researchers reported that the overall safety profile of drugs used for treating spondyloarthritis is generally good, with serious adverse events being rare, but emphasized the need for rheumatologists to tailor treatments and closely monitor patients for potential adverse events.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.

This study found that glycine treatment inhibited melanogenesis in B16F0 melanoma cells and reduced melanin content in C57BL/6J mice by down-regulating tyrosinase protein levels.

This review discusses the pathophysiology, diagnosis, and management of functional hypothalamic amenorrhea in adolescent girls and reports no new clinical results.

This study found that TSA restored the hair-inductive capacity of skin-derived precursors in mice by enhancing BMP gene expression and signaling through histone acetylation.

This study found that dihydrotestosterone (DHT) regulates the degradation of p27 in MCF-7 breast cancer and OVCAR-3 ovarian cancer cells, involving SKP2 as a key factor.

In this study, 17β-estradiol increased VEGF production in differentiated THP-1 cells, while dihydrotestosterone counteracted this effect by modulating adenylate cyclase activity.

This study found that manipulating AKR1D1 expression in human liver cells effectively regulates glucocorticoid clearance and receptor activation, highlighting its role in liver-specific steroid hormone regulation.

This study found that neonatal finasteride treatment in male rats altered hippocampal GABAA receptor subunit expression and led to increased anxiety-like behavior in response to progesterone in adulthood.

This study found that 6-gingerol, a component of ginger, suppresses hair growth rather than promoting it, both in vitro and in vivo, suggesting potential use in hair removal treatments.

This article provides a guide for surgeons on repairing poorly executed hair transplants, emphasizing meticulous techniques and optimal use of limited hair supply to achieve cosmetic improvements.

This study found that PEGylation of nanoparticles enhances their penetration into hair follicles, with higher molecular weight PEG resulting in deeper follicular delivery.

Clotrimazole, an antifungal cream, may safely reduce skin pigmentation by breaking down the enzyme needed for making melanin.

This study found that ATM protein plays a crucial role in protecting human hair follicle melanocytes from oxidative stress, which is linked to the greying of hair.

In this study, adipose tissue secretome was shown to enhance oxidative stress resistance and promote cell proliferation in vitiligo cells, suggesting a potential natural treatment approach.

This laboratory study found that activated platelet‐rich plasma supernatant enhanced hair growth signaling pathways in cultured human dermal papilla cells, suggesting potential for treating androgenic alopecia.

This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

This study found that mice lacking myelin protein zero-like 3 (Mpzl3) had reduced body weight and adiposity despite increased food intake, which was linked to higher energy expenditure and improved glycemic control.

This review discusses the roles of epithelial-mesenchymal interactions and dermal papilla in hair follicle growth and cycling, but it reports no new clinical results.

This study found that procyanidin oligomers from apples and barley may stimulate hair growth by promoting hair epithelial cell proliferation and protecting them from apoptosis via MEK activation in a murine model.

This study found that exosomes from hair follicle mesenchymal stem cells overexpressing lncRNA H19 promoted diabetic skin wound healing by enhancing cell proliferation, migration, and reducing pyroptosis.
