This study found no consistent differences between the posterior vertex and occipital region for hair hormone analysis, but noted significant variations in specific hormone concentrations, highlighting the need for standardized sampling practices.

This study found that polyamine levels were higher in the vertex hair than in occipital hair among patients with pattern baldness, suggesting a relation to hair loss development in the scalp's vertex region.

This study found that hair from the vertex posterior is a reliable sampling region for detecting zolpidem intake, showing consistent drug concentration and peak position compared to other scalp regions.

Congenital triangular alopecia can occur outside the typical fronto-temporal region.

This study found that low level laser therapy with a HairMax LaserComb improved hair counts and tensile strength in patients with androgenetic alopecia, particularly in males and vertex areas.

This article reviews conventional and alternative treatments for hair loss, noting FDA-approved drugs like Minoxidil and Finasteride, but reports no new clinical findings; the authors highlight concerns about side effects, spurring interest in herbal remedies.

This case report describes a 54-year-old man diagnosed with fibrosing alopecia in a pattern distribution, presenting with follicular inflammatory lesions and scleroatrophy on the scalp.

This proposal presents a standardized system for naming areas of the balding scalp to improve communication among hair restoration professionals, defining major regions and introducing new landmarks.

This study observed that 54% of men with male pattern hair loss showed hair growth improvement in the vertex region after 6 months of treatment with oral finasteride.

This study reports that quantitative trichoscopy, while noninvasive and convenient, provides less accurate hair density data compared to invasive histopathologic examination, which was demonstrated in a sample of adult Chinese individuals without alopecia.

This abstract reviews existing hair loss treatments, highlighting FDA-approved drugs like Minoxidil and Finasteride while noting growing interest in herbal alternatives due to concerns about potential long-term side effects.

This study captured digital images of hair regions in healthy individuals and patients with androgenetic alopecia to analyze and compare the number of follicular units and hairs using software.

This study reports that a new multi-slit knife for hair transplant procedures reduces surgical time and increases precision by enabling quick creation of equidistant "brick-pattern" sagittal slits.

This study found that combining PRP with topical minoxidil or finasteride significantly improved hair density and thickness, with patient satisfaction highest for multiple treatment combinations and longer durations.

In this research, a thorough review of hair loss issues and treatments identified the effectiveness of minoxidil and finasteride for alopecia in the scalp's vertex region, but noted concerns about their potential long-term effects, leading to increased interest in herbal therapies.

In this randomized clinical trial, oral minoxidil was not superior to topical minoxidil in increasing hair density in men with androgenetic alopecia over 24 weeks, though photographic analysis suggested oral minoxidil may work better on the vertex area of the scalp.

This article discusses conventional and alternative treatments for hair loss but presents no new findings, highlighting concerns about the unknown long-term effects of approved drugs.

Human hair growth involves active, resting, and intermediate phases, and examining plucked hairs can teach students about hair biology and diseases.

This study found that topical minoxidil 5% remains the most common treatment for androgenic alopecia due to its high tolerability and patient satisfaction, but topical sildenafil 2% shows promise as an alternative, especially with positive hair thickness outcomes in certain areas.

This article proposes a standardized naming system for areas of the balding scalp to improve communication among hair restoration professionals, but it reports no clinical results.

This study found that platelet-rich plasma therapy may offer a simple and cost-effective treatment option for androgenetic alopecia in men, with around 70% of participants showing mild to excellent improvement.

This study reported that a new PRP application protocol with two treatments enhanced hair growth metrics in the vertex region of androgenetic alopecia patients within six months.

This article suggests a hypothesis that scalp neuropathy may contribute to androgenetic alopecia, focusing on the potential role of the arrector pili muscle's innervation in maintaining hair health.

This review discusses the surgical methods of hair restoration, highlighting the density benefits of scalp reduction and rotation, but reports no new clinical findings.

In this study, topical finasteride 0.25% showed sustained effectiveness over 52 weeks, especially in the frontotemporal areas of men with androgenetic alopecia, while maintaining an excellent safety profile.

This article reviews current diagnostic and treatment approaches for androgenetic alopecia but reports no new results, focusing on its progression and medical management options.

This study examined 15 female patients with hypothyroidism to investigate the characterization of their alopecia and ruled out other causes, using medical histories, and clinical, trichoscopic, and histologic findings.

In this study, researchers used trichoscopy to establish standardized findings for normal hair and scalp characteristics in 360 healthy males, noting significant age-related differences in hair diameter variability and identifying potential pathological indicators like colored dots and scarring not present in healthy individuals.

This study found that quantitative trichoscopy is a simple and effective method for determining hair density and thickness in Egyptians, establishing baseline values for clinical hair loss investigations.

This study suggests that collecting hair samples from all scalp regions may be a viable alternative for measuring cortisol in individuals with Afro-textured or extremely short hair, aligning results with traditional methods.
