This study examined lipid changes in rat models of polycystic ovarian syndrome, finding that letrozole and dihydrotestosterone treatments led to some lipid alterations similar to human PCOS, while other changes were unique to the models.

This study found that dihydrotestosterone treatment may be more beneficial for height in children with 5-α-reductase type 2 deficiency compared to testosterone enanthate, especially in the prepubertal period.

This study highlights the diverse applications of *Perilla frutescens* in traditional medicine, cuisine, and industrial settings, noting its significant antioxidant and antimicrobial properties in experimental models, as well as research efforts to enhance its bioactive content and ensure safety and standardization.

This study found that exosomes derived from bovine colostrum promoted hair growth in mice by activating the Wnt/β-catenin pathway, with effects similar to minoxidil but without adverse effects.

This study found that combining fructose and DHT in rats successfully mimicked the clinical phenotypes of non-lean PCOS, providing a novel rodent model for this condition.

This article describes the growth and characteristics of saw palmetto and its fruit but reports no new research results.

This chapter reviews ethosomes for targeted drug delivery to the scalp in androgenetic alopecia and reports no clinical results; the authors emphasize reducing systemic side effects.

This review discusses the causes and management of hirsutism, recommending low-dose oral contraceptives with flutamide over cyproterone-containing preparations, but reports no new clinical findings.

This article reviews the use of anti-androgens for dermatological conditions linked to androgen involvement and reports encouraging clinical experiences in females, with use in males limited to specific conditions due to toxicity concerns.

This study found that applying an ethanol extract of Prasiola japonica improved hair regrowth, length, and follicular density in testosterone-induced hair loss conditions in mice, while also promoting dermal papilla cell proliferation and reducing dihydrotestosterone production, though effects were less pronounced than those of minoxidil.

In this study, quercetin nanocrystals stabilized with glycyrrhizic acid were developed as a new treatment strategy for androgenetic alopecia, which significantly reduced DHT levels and improved hair regrowth in a mouse model, indicating synergistic potential for clinical application.

In a murine model of androgenetic alopecia, this study found that the newly designed IGF-1 biomimetic peptide Ac-GFFY-IGF led to faster and superior hair regrowth compared to minoxidil, suggesting potential for improved human therapies.

This study observed that a combination of sinapic acid and glabridin from Zhimo herbal extract improved hair growth and reduced oxidative stress in a DHT-induced model of androgenetic alopecia in mice by preventing ferroptosis and stabilizing β-Catenin, offering potential application for AGA treatment.

This study found that administering adipose-derived stem cells with ATP improved hair regrowth in male mice with androgenetic alopecia, while the combination was less effective in female mice.

In this study, the researchers reported that a novel exosome-based treatment, EX104, effectively reversed hair follicle miniaturization and promoted hair growth in a mouse model of androgenetic alopecia, showing results comparable to minoxidil and surpassing it in stimulating capillary growth and follicular proliferation.

This study found that essential oils from A. sinensis and L. sinense 'chuanxiong' were safe and significantly promoted hair regrowth in mice with dehydrotestosterone-induced androgenetic alopecia, outperforming 3% minoxidil in follicle number and dermal thickness improvements, suggesting potential use in hair loss treatments.

This study found that Kyoh®, a flavonol-rich extract from rocket leaves, may promote hair growth by enhancing the expression of hair growth-related genes in laboratory conditions.

This study found that human adipose-derived MSC exosomes (hADSC-Exos) may enhance dermal papillary cell proliferation and migration by activating the Wnt/β-catenin signaling pathway, potentially reversing the effects of dihydrotestosterone in androgenetic alopecia.

In this study, MitoQ was found to enhance hair growth and reverse DHT-induced hair loss in a mouse model of androgenetic alopecia by mediating the WNT/β-catenin pathway and increasing CYP19A1 expression, suggesting potential as a therapeutic intervention.

This study found that cell-free fat extract (CEFFE) enhanced hair growth in mice with androgenetic alopecia by increasing hair follicle density and promoting proliferation while regulating the DHT/AR pathway.

This study describes androgenetic alopecia as a common non-scarring hair loss condition primarily influenced by genetic factors and androgen sensitivity, notably impacting psychosocial well-being, especially in females and younger males seeking treatment.

This study suggests that oleanolic acid may promote hair growth in mice with testosterone-induced androgenetic alopecia by activating the Wnt/β-catenin pathway and influencing various molecular levels.

This article discusses the various administration methods and considerations for testosterone replacement therapy, highlighting the importance of individualized therapeutic monitoring and potential adverse effects, but reports no new clinical results.

This chapter reviews the role of hair transplantation in gender affirming procedures for transitioning patients but reports no new clinical findings.

This study reported that a curcumin-zinc microneedle patch improved hair regrowth and wound healing in animal models, suggesting potential as a versatile treatment for hair loss.

This article reviews the use of saw palmetto extract from a dermatologist's perspective, discussing its traditional role in treating androgenic alopecia and other androgen-related dermatological conditions, but it does not report specific research findings or results.

In this study, creatine supplementation over 12 weeks showed no effect on androgen levels or hair follicle health in healthy young males, challenging the belief that creatine causes hair loss.

This review examines the hormonal causes of hair loss, noting how androgen excess can lead to follicle miniaturization and linking estrogen deficiency and thyroid dysfunction to common alopecia types. It further discusses hormonal treatments such as finasteride, dutasteride, and spironolactone.

This study found that exosomes from adipose mesenchymal stromal cells, particularly those carrying miR-122-5p, may enhance hair follicle regeneration in androgenic alopecia by targeting the TGF-β/SMAD3 axis.

The authors conclude that optimizing hair shaft production and appearance may best be achieved by integrating biological, chemical, and physical intervention strategies.
