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 study established standard trichoscopy norms for adult white females, providing benchmarks for hair thickness, percentage of thin hairs, and pilosebaceous units with single hair across different scalp areas.

This article reviews monilethrix, a rare genetic hair disorder causing brittle hair and alopecia, and emphasizes the need for clinical diagnosis and characteristic tricoscopic findings.

This study compared the diagnostic effectiveness of Folliscope and Trichoscope in 100 men with androgenetic alopecia, concluding that using both methods enhances diagnostic accuracy by providing complementary insights—Trichoscope highlights patterns while Folliscope offers objective measurements.

This study suggests that clinically apparent fragile hair in children is rarely linked to trichothiodystrophy, and the tiger-tail pattern is not wholly specific to this diagnosis.

This review discusses the use of trichoscopy for diagnosing alopecia and reports no new clinical results, emphasizing its role in identifying vascular and follicular features.

In this study, trichoscopic examination revealed that variations in hair diameter were more common in certain types of alopecia affecting the frontal scalp, suggesting the importance of evaluating the entire scalp for accurate diagnoses, although limitations include a single center design and small sample size.

In this study, deep phenotyping of 68 patients with XPD gene defects successfully separated individuals by clinical diagnosis and survival status, potentially improving diagnosis and prognosis for xeroderma pigmentosum and trichothiodystrophy.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

In this study, researchers evaluated trichoscopy in diagnosing non-scarring alopecia and found diagnostic value in observing diverse hair diameters in androgenetic alopecia, black dots and broken hairs in alopecia areata, and empty follicles in telogen effluvium, supporting trichoscopy's utility in differentiating alopecia types.

This case study examined a 72-year-old woman with unique hair shaft constrictions consistent with monilethrix, despite features atypical for this condition, ultimately reaching a diagnosis that led to successful improvement using oral minoxidil and reduced hair trauma.

Individualized treatment plans are crucial for managing excessive hair growth.

In this study, trichoscopy was identified as a useful non-invasive tool to aid in the diagnosis of female pattern hair loss, with peri pilar sign and hair diameter variability being common findings.

This study explores hypertrichosis, a condition of excessive hair growth, highlighting its classification, diagnostic methods, and potential treatments. The authors emphasize the importance of individualized approaches and further genetic research to enhance treatment options for this primarily cosmetic issue that can signal systemic diseases.

In this study, researchers evaluated trichoscopic features in 500 Egyptian patients with patchy hair loss and found specific patterns, such as perifollicular scale with 90% sensitivity and 99.5% specificity, which effectively aid in diagnosing primary cicatricial alopecias.

The current state and future directions of the field that studies the connection between the mind and skin are discussed.

This case report described a 12-year-old girl initially misdiagnosed with alopecia areata who showed improvement in trichotillomania symptoms after treatment with psychotropic drugs and N-acetylcysteine, highlighting the need for more research to develop standardized treatment guidelines for this chronic condition.

This article discusses the trichoscopic diagnosis of temporal triangular alopecia, but reports no new clinical results.

This study aimed to identify trichoscopic features that help differentiate between tinea capitis and alopecia areata in children, enhancing diagnosis and treatment decisions visually and non-invasively.

Different treatments are effective for hair loss conditions, but results vary by individual factors.

This study found that trichorrhexis nodosa, a cause of unexplained hair loss, is often linked to mechanical trauma rather than a metabolic defect.

This case study highlights how trichoscopy helped differentiate between diffuse alopecia areata and trichotillomania in an 11-year-old girl, demonstrating its importance in distinguishing hair disorders with similar presentations.

This paper examines three case studies of hair disorders through the lens of analytical psychology, suggesting that psychological factors and symbolic meanings may contribute to their onset and persistence.

This review outlines current treatment strategies for trichotillomania, noting cognitive-behavioral therapy's success, while highlighting the promise and limitations of various pharmacological options.

This study found that exclamation mark hairs are the only trichoscopic feature that can differentiate clinically suspicious SA from AA.

This case report identifies an association between trichothiodystrophy and a urologic malformation with primary hypercalciuria, adding to the spectrum of TTD-related abnormalities.

This paper highlights trichodynia as a distinguishing symptom of telogen effluvium, but it does not present new clinical findings.

The authors concluded that trichoscopy is a valuable noninvasive tool for diagnosing and monitoring nonscarring alopecia, aiding in the identification of new hair signs in difficult cases.
