In this study, researchers found that hair alterations such as frontal-occipital inversion in males and a high occipital hairline may aid in diagnosing the uncommon condition TRPS.

This case report highlights that trichoscopy facilitated early diagnosis of discoid lupus erythematosus of the scalp in a 9-year-old boy, with oral prednisone minipulse therapy leading to complete remission and hair regrowth.

This study found that trichoscopy is a valid and sensitive tool for diagnosing and evaluating eyebrow involvement in lichen planopilaris and frontal fibrosing alopecia.

In this study, patients with androgenetic alopecia who received type A botulinum toxin treatment showed increased follicle width and length at the vertex and left frontal area over three months, but no significant changes in follicle or hair count compared to the control group.

This pilot study detailed the use of Hair-to-Hair-matching technology™ in a clinical trial to assess botulinum toxin's efficacy in treating male androgenetic alopecia, providing a precise method for evaluating hair count and thickness changes over time.

This chapter reviews the use of trichoscopy in hair transplantation, offering tips for hair restoration surgeons and assisting pathologists in understanding the procedure, but reports no new clinical results.

This review discusses how trichoscopy is becoming a preferred non-invasive diagnostic tool over trichograms for evaluating hair disorders, although it reports no clinical results.

This article reviews the complexities and challenges in hair transplant procedures, emphasizing the role of micro-inflammation and the usefulness of trichoscopy for detecting complications, and reports no new clinical results.

This study found that infrared thermography might be a useful non-invasive tool to help diagnose frontal fibrosing alopecia by identifying active phases of the disease.

This article reviews the use of trichoscopy for diagnosing and monitoring various scalp conditions, but it presents no new experimental findings; the authors emphasize its precision in noninvasive evaluation.

This review discusses how trichoscopy, a hair and scalp examination method, helps in diagnosing various hair diseases by identifying specific structural features but provides no new clinical findings.

This study reported that Asian patients have few racial differences in trichoscopy compared to Caucasian patients, except for certain features like greater mean hair diameter and masking effects by normal skin color.

Trichoscopy is a helpful and quick method to identify different types of hair loss in women.

This source discusses the characteristics and clinical presentation of androgenetic alopecia, emphasizing the importance of early recognition and grading for administering therapy and the role of trichoscopy in diagnosis and monitoring treatment response.

This study found that among women with frontal fibrosing alopecia, 100% showed dermoscopic elements suggestive of the condition, with perifollicular erythema often indicating disease activity.

This letter discusses congenital triangular alopecia (TTA), a non-scarring hair loss condition often seen in children, without reporting new clinical findings.

In this case report, researchers describe a 44-year-old woman with refractory patch alopecia areata achieving complete hair regrowth using a multi-modal approach of systemic and topical cholecalciferol with microneedling, although systemic vitamin D repletion remains a significant confounder.

This study found that growth factor concentrate provides quicker improvements for patterned hair loss, but platelet-rich plasma offers more sustained benefits after treatment.

This study found topical finasteride and minoxidil both improved hair loss clinically and trichoscopically more effectively than spironolactone in women with female pattern hair loss.
