This article reviews the history, biology, genetics, prevention, conventional treatments, and herbal alternatives for hair loss, but reports no new research findings.

This study found that a testosterone patch and gel showed bioequivalent testosterone levels in hypogonadal men, but the patch mimicked a natural circadian profile, while the gel resulted in higher dihydrotestosterone levels.

This review highlights the traditional use and potential therapeutic activities of Asiasari Radix in drug discovery, but it reports no new clinical results.

This study found that miniaturized hair follicles from pattern alopecia can regenerate rapidly when transplanted onto mice and may grow as well as or better than terminal hairs.

This source highlights the essential role of androgens in women's health, noting their impact on various body systems and the critical need for more research on androgen therapies regarding side effects, patient selection, and laboratory standardization.

In this study using a rat model, discontinuing dutasteride improved some relaxant responses but did not fully restore erectile function, indicating a potential time-dependent detriment of the drug.

Finasteride effectively blocks rat enzymes, but with varying methods and strength.

This review discusses the clinical applications and adverse effects of 5-alpha reductase inhibitors for treating benign prostatic hyperplasia and androgenic alopecia, noting controversies around their implications for other diseases, without reporting new results.

In this study, high-dose dutasteride significantly reduced several core symptoms of PMDD compared to placebo, supporting the role of neurosteroids in this condition.

This review discusses various prostate cancer prevention strategies and reports no new clinical results; the authors highlight the need for ongoing research in this area.

This article discusses the benefits of follicular unit transplantation for male hair restoration, highlighting its ability to achieve natural-looking results with minimal recovery time and low risk of complications, and reports no new clinical results.

This study found a very strong positive correlation between sebum levels and the severity of androgenetic alopecia in men.

This study concluded that dutasteride 0.5 mg/day improved hair growth in patients with androgenetic alopecia over six months but was associated with a higher prevalence of sexual dysfunction.

In this study, low-dose oral minoxidil was found to have a favorable safety profile for treating alopecia, with mostly mild side effects, in both general and hypertensive populations.

This study found that LY320236 is a competitive inhibitor of type I and a non-competitive inhibitor of type II steroid 5alpha-reductase, indicating its potential as a dual inhibitor with differing modes of activity.

This study found that Phyllanthus urinaria extract displayed significant anti-alopecia properties in a mouse model, showing potential as an anti-5α-reductase agent for androgenic hair loss.

Scale created to measure hair loss in men and women; MK-386 reduces acne; Niaspan treats dyslipidemia; minoxidil increases heart rate.

Minoxidil given intravenously caused small changes in diastolic blood pressure and increased heart rate at higher concentrations in patients with high blood pressure.

This phase II study found that a 0.05% topical dutasteride solution was more effective than oral finasteride (1 mg/day) in increasing hair count and width in males with androgenetic alopecia over 24 weeks, without causing irritation.

This study analyzed the formulation and stability of pomade containing peppermint oil and minoxidil, determining that a particular formulation with 1% paraffin yielded optimal physical and stability characteristics for promoting hair growth, making it the best choice among the tested options.

This review discusses nearly 70 patent applications for the treatment of androgenetic alopecia and other hair conditions, highlighting the mechanisms of action explored but reports no clinical results.

In this randomized study, intradermal injections of dutasteride effectively improved androgenetic alopecia in 15 male patients, showing significant clinical improvement within one month and being well-tolerated without notable side effects, though the improvement was negatively correlated with longer disease duration.

This review discusses the pharmacologic effects, safety, and efficacy of dutasteride and finasteride for BPH, finding similar clinical benefits but greater DHT reduction with dutasteride and reports no new trial results.

This study found that co-administration of ketoconazole significantly altered the pharmacokinetics of dutasteride in rats, suggesting an interaction potential between dutasteride and azole antifungal drugs.

This study found that dutasteride was more effective than finasteride in reducing total prostate volume and PSA levels and improving symptoms in patients with benign prostate hyperplasia.

This study found that combining oral minoxidil, oral dutasteride, and dutasteride mesotherapy was the most effective treatment for androgenetic alopecia, with improved outcomes at 12 months and a favorable safety profile, compared to other treatment combinations.

This review highlights the need for a deeper understanding of 5alpha-reductases and neuroactive steroids to reduce potential adverse effects of 5alpha-reductase inhibitors used for conditions like benign prostatic hyperplasia and androgenic alopecia, but reports no new clinical results.

This review concludes that finasteride and dutasteride are the most evidence-supported oral treatments for androgenetic alopecia, with dutasteride offering slightly greater hair count improvements and both affected by genetic response modifiers.

This study reviews the effectiveness and safety of finasteride and dutasteride for treating androgenetic alopecia, highlighting that dutasteride reduces DHT more deeply than finasteride, with genetic factors influencing patient response and both drugs being evidence-supported options for men and women.

This review outlines the physiological roles of 5a-reductases and highlights the need for further research to better understand their function and minimize adverse effects from their inhibitors used in treatment.
