Pressure alopecia (PA) is an uncommon type of hair loss due to ischemic changes of the scalp, as a result of prolonged immobilization. Clinically, it often appears within the 1 month of the trigger and tends to resolve spontaneously within 4 months. If the duration of the immobilization is longer, irreversible alopecia can be developed. Trichoscopy is usually nonspecific, being black dots, broken, and dystrophic hairs the most frequent findings. However, yellow dots and thin hairs have also been reported. We herein present two patients with PA, one with a recent development and another one with a long-lasting alopecia. Both of them showed keratotic follicular plugs and thin hairs as the main trichoscopic findings.

Article Synopsis
- Lichen planopilaris (LPP) is a type of hair loss condition caused by lymphocytic activity, leading to various patterns of permanent hair loss.
- Trichoscopy is a crucial diagnostic tool that helps identify specific signs of LPP, aiding in the diagnosis of different types of lichenoid alopecia.
- Early recognition of trichoscopic signs is essential for timely treatment, which may help prevent the progression of LPP to irreversible scarring.

Background: Frontal fibrosing alopecia (FFA) is a scarring hair loss condition primarily affecting the frontotemporal hairline and often leading to partial or complete loss of eyebrows in a significant number of cases. It is characterized by slow progression and typically shows poor response to available treatments. Diagnosis relies on clinical, trichoscopic, and histopathological assessments, with specific criteria proposed by Vañó-Galván et al.

Article Synopsis
- Dermoscopy and trichoscopy are noninvasive diagnostic tools used to identify structures and conditions related to hair and scalp disorders that aren't visible to the naked eye.
- A study involving 200 Egyptian children with focal non-cicatricial alopecia identified alopecia areata and tinea capitis as the most common diagnoses, with trichoscopy highlighting specific features that aid in distinguishing these conditions.
- The findings suggest that incorporating trichoscopy into routine evaluations greatly enhances diagnostic accuracy and helps in the effective treatment of hair loss disorders in children.
