The authors concluded that trichoscopic examination can be useful for diagnosing syphilitic alopecia in patients with idiopathic alopecia, though the findings are nonspecific and further studies are needed.

This study found that high-frequency ultrasonography may effectively distinguish different stages of alopecia areata and differentiate it from other scalp conditions.

This study found that androgenetic alopecia was the most common cause of frontal hairline recession in Egyptian female patients, supporting the use of trichoscopy as a noninvasive diagnostic tool.

Clinical signs don't match inflammation levels in lichen planopilaris and frontal fibrosing alopecia.

This study determined that trichoscopy is a sensitive and specific tool that effectively aids in diagnosing alopecia in women, especially when clinical diagnosis is uncertain.

This study found that Follicular Maps, derived from trichoscopic images, remained consistent over time and unaffected by hair cycling or noncicatricial alopecia, offering a precise tool for diagnosing and monitoring hair and scalp conditions.

This case report found that dermoscopy, showing characteristic "comma" and "corkscrew" hairs, effectively identified tinea capitis in a 7-year-old girl, allowing for early treatment before confirmation with fungal culture.

In this study, trichoscopic examination revealed that patients with androgenetic alopecia had significantly more yellow dots, pilosebaceous units with one hair, and increased perifollicular hyperpigmentation compared to healthy controls.

In this correspondence, researchers reported that very-low-dose oral minoxidil (0.25 mg/d) showed some effectiveness in stabilizing trichoscopic parameters in male androgenetic alopecia. However, their analysis suggests that higher doses (2.5–5 mg/d) may lead to better clinical responses with similar rates of adverse events.

This review discusses the characteristic trichoscopy patterns useful in differentiating lichen planopilaris and frontal fibrosing alopecia from similar conditions but reports no new clinical results.

This case report describes how trichoscopy helped diagnose tinea capitis disguised as female pattern hair loss in cases of endothrix infection, highlighting its usefulness in avoiding misdiagnosis.

This abstract reviews the bubble hair abnormality caused by high-temperature styling tools and reports no new experimental results.

This review describes distinct trichoscopic findings for various alopecias in individuals with skin of color, but reports no new clinical results.

This study found that a deep learning model can potentially improve the diagnosis and staging of alopecia areata with high accuracy and reliability.

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 study concluded that exclamation mark hairs are the most reliable marker of disease activity in alopecia areata, with broken hairs, triangular hairs, and black dots also increasing the probability of active disease.

In this study, chemotherapy-induced alopecia in cancer patients showed specific trichoscopic patterns and abnormal hair shaft morphology, suggesting intermittent follicle damage from chemotherapy, but larger studies are needed for confirmation.

This case study suggests that trichoscopic examination of the beard can aid in diagnosing frontal fibrosing alopecia in men, especially when challenging to differentiate from androgenetic alopecia.

This pilot study found that among male androgenetic alopecia patients, 2.5 mg oral minoxidil with platelet-rich plasma led to higher patient satisfaction than 1.25 mg, though hair count improvements were not statistically significant.

In this study, researchers found that topical ketoconazole showed delayed hair growth compared to minoxidil in female pattern hair loss but had fewer side effects, though patient satisfaction was similar for both treatments.

This study found that pigmented vellus and upright regrowing hairs are the only predictive trichoscopic markers of hair regrowth in patients with alopecia totalis and universalis.

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.

This study identified two distinct trichoscopic patterns in the mid-frontal scalp of patients with frontal fibrosing alopecia who also display clinical features of androgenetic alopecia.

This study identifies specific trichoscopic features such as empty follicles and perifollicular erythema in Caucasians with frontal fibrosing alopecia, which may assist in diagnosis and monitoring, but stresses the need for further research due to limited demographic data.

This systematic review evaluated 60 studies on trichoscopy in hair and scalp disorders, revealing gaps in accounting for variables like disease stage or hair texture, and underscoring a need for more comprehensive analyses to fully understand trichoscopic patterns.

This study reviewed 39 studies with 3204 patients to identify characteristic trichoscopic findings in alopecia areata, highlighting yellow and black dots, broken, short vellus, and tapering hairs as key indicators. It found no single diagnostic trichoscopic finding but observed trichoscopy's utility in monitoring treatment response.

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 case study reports a 58-year-old woman experiencing pressure-induced alopecia with concomitant acute telogen effluvium after severe COVID-19, suggesting a potential link between prolonged hospitalization and hair loss.

This study found that metabolic syndrome negatively affected the response to intradermal dutasteride injection in female pattern hair loss, with participants showing reduced terminal hair and increased vellus hair compared to those without the syndrome.

This report describes a rare case of alopecia areata coexisting with primary scarring alopecia, diagnosed through detailed trichoscopic investigation, highlighting the importance of comprehensive examination for accurate diagnosis.
