Folliculotropic Mycosis Fungoides (FMF) is a rare variant of Mycosis Fungoides involving the scalp leading to alopecia. The clinical and trichoscopic features in 18 patients were analyzed and compared with the reports in the literature. Gender, age, disease stage, site of onset were taken into consideration. Clinical and trichoscopic analyses were performed on each patient. From a clinical point of view, Folliculotropic Mycosis Fungoides lesions involving the scalp presented as generalized alopecia (27.8%) or patchy-plaque alopecia (72.2%). Trichoscopic analysis revealed six most frequent features: single hair (83.3%), dotted dilated vessels (77.8%), broken-dystrophic hairs (66.7%), vellus hairs (61.1%), spermatozoa-like pattern vessels (55.6%), and yellow dots (55.6%). Additional identified trichoscopic patterns were dilation of follicular openings, scales-crusts, purpuric dots, short hair with split-end, pigtail hairs, perifollicular hyperkeratosis, milky-white globules, black dots, white dots/lines and absence of follicular dots. These trichoscopic features were further correlated to clinical presentations and stage of the disease. The rarity of the disease is a limitation. The relatively high number of patients allowed to identify several clinical and trichoscopic patterns that could be featured as specific or highly suspicious for FMF in order to consider trichoscopy as a complementary diagnostic approach and improve the differential diagnoses between FMF and other scalp disorders.

Male androgenetic alopecia (MAA) is quite common and worsens with age, with a significant impact on quality of life, and is increasingly a reason for consultation with a dermatologist. The etiopathogenesis of MAA is multifactorial and genetic and hormonal influences stand out. MAA starts with the process of follicular miniaturization in diverse phenotypic patterns.

Background: Scalp seborrheic dermatitis (SD) is a chronic, recurrent inflammatory skin condition associated with scalp sebum secretion and dysbiosis.
Aims: The aim of this study is to evaluate the efficacy and safety of a topical salicylic acid/piroctone olamine/zinc salt of L-pyrrolidone carboxylate (Zinc PCA) scalp pre-application gel in combination with a salicylic acid/piroctone olamine/antimicrobial peptide cleansing lotion for the treatment of moderate to severe scalp SD.
Patients/methods: In this prospective cohort study, 20 patients with moderate to severe scalp SD were treated with a combination of the scalp pre-application gel and cleansing lotion for 4 weeks (one tube of the pre-application gel per week and the cleansing lotion used every 1-3 days depending on the frequency of hair washing).

Introduction: Alopecia areata (AA) is a non-scarring autoimmune disease characterized by patchy hair loss. The aim of this study was to validate a novel trichoscopic scoring tool, the Severity TRichoscopy Index for Alopecia Areata (STRIAA), for rapid assessment of AA severity.
Methods: Anonymized images from 340 patients were scored by two independent raters who analyzed four scalp areas (vertex, occipital, and left and right parietal) for trichoscopic signs: black dots, yellow dots, exclamation mark hairs, broken hairs, and short vellus hairs.
