This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

In this study on Iranian patients with non-scarring alopecia, researchers found that androgenetic alopecia was the most common subtype, with perifollicular inflammation observed more in males. They reported that transverse sectioning is generally sufficient for diagnosis, but combining with vertical sectioning provides more comprehensive information.

In this study using human cell cultures, type 1 5α-reductase was found to vary in both protein heterogeneity and expression levels across different types of skin cells.

This study observed that patients with androgenetic alopecia in a western Indian population had a significantly higher prevalence of metabolic syndrome compared to a matched control group, suggesting that individuals with this type of hair loss may benefit from screening for metabolic syndrome.

In this study, significant improvements in Androgenetic Alopecia were observed with both PRP and SVF therapies, with SVF showing greater effectiveness in increasing terminal and vellus hair counts.

In this study, trichoscopy was highlighted as a valuable diagnostic tool for traction alopecia, particularly in black women, revealing common signs like vellus hair and hair casts, although it requires a suggestive clinical history for effective use.

This review discusses the increased prevalence of androgenic alopecia in men and women, highlighting the limited FDA-approved treatment options, and reports no clinical results; the authors note adherence challenges due to prolonged drug use.

This study found that a notable percentage of COVID-19 patients experienced post-infection telogen effluvium, although no significant associations with infection-related factors were identified.

Frontal fibrosing alopecia is a scarring hair loss condition mainly affecting postmenopausal women, with unclear causes.

Dermoscopy helps diagnose frontal fibrosing alopecia by identifying specific scalp features.

This review discusses various therapeutic options for frontal fibrosing alopecia and highlights the need for more research, as existing data are largely retrospective and lack precise treatment guidelines.

This review discusses post-COVID hair loss, attributing it to potential pathogenic factors like cytokines and viral effects, and suggests that full recovery without specific treatment is expected.

This review presents European expert guidelines for diagnosing androgenetic alopecia across genders but reports no new clinical findings; it emphasizes the importance of trichoscopy for differentiating similar conditions.

This study observed that mature neutrophils and their extracellular traps inhibit wound-induced hair follicle neogenesis in mice, despite being stimulated by pro-regenerative cues.

This review discusses traction alopecia, its causes, and common treatments, noting a lack of data on effective treatment options; the authors emphasize altering hair care practices to potentially reverse early-stage alopecia.

This review discusses the diagnostic features of androgenetic alopecia through trichoscopy and reports no clinical results; it emphasizes hair shaft variability and yellow dots as key indicators.

This review examines the clinical presentation of alopecia areata in children and compares it to adult-onset cases, noting that data on pediatric cases is scarce and often varies, with reported onset typically between ages 6 and 12.

This case report documents a rare instance of triangular temporal alopecia in an adult woman, emphasizing the importance of correct diagnosis to avoid unnecessary treatments, and reviews the literature on TTA.

Some types of hair loss can be reversed, others are permanent, and treatments vary by type.

This report describes the first known case of frontal fibrosing alopecia in a genetically unrelated couple, suggesting the potential role of environmental factors in its development.

This case series reported that telogen effluvium may reveal underlying traction alopecia, emphasizing the importance of recognizing this to ensure accurate diagnosis and treatment.

This study found that Vitamin B12 deficiency was more common in patients with chronic telogen effluvium than in healthy controls.

This article discusses the mechanisms of androgenetic alopecia and explores possible explanations for minoxidil's effect on hair growth but reports no new results.

This review highlights potential therapeutic mechanisms of natural products for androgenetic alopecia, suggesting they may modulate signaling pathways and have anti-inflammatory and antioxidant effects.

This case report describes an unusual trichofolliculoma in a 54-year-old man, notable for its prominent mucinosis, which is typically not as abundant in such tumors.

In this study, researchers found that adults with alopecia areata exhibited trichoscopic features of empty follicular openings and tulip hair, while children showed more honeycomb pigment patterns and pohlpinkus constriction on their scalp lesions.

This review addresses the causes, mechanisms, and treatment options for the most common non-scarring alopecias in females, including telogen effluvium, alopecia areata, and female pattern hair loss.

This placebo-controlled study found that topical procyanidin B2 significantly increased total and anagen hair counts in men with androgenetic alopecia over 16 weeks compared to placebo, suggesting it as an effective and safe treatment option.

This review highlights that alopecia areata, a common type of hair loss, currently lacks preventive or curative treatments, and traditional therapies such as minoxidil and corticosteroids offer inconsistent results, necessitating patient-consensual treatment planning.

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.
