Summary
Background
Frontal fibrosing alopecia (FFA) is a chronic cicatricial alopecia with an increasing incidence and unknown aetiology.
Aim
To identify possible environmental and hormonal factors ...related to FFA.
Methods
We conducted a multicentre case–control study paired by sex and age, and recruited 664 women (335 cases and 329 controls) and 106 men (20 cases and 86 controls). Study subjects completed an exhaustive questionnaire enquiring about pharmacological, environmental, hormonal, social, job exposure, lifestyle, drugs and diet factors to which they were exposed at least 5 years prior to the onset of the disease.
Results
For women, there was a statistical association between alopecia and history of pregnancy (OR = 1.6; 95% CI 1.06–2.41), use of facial sunscreen (OR = 1.6; 95% CI 1.06–2.41) and hormone replacement therapy (HRT) (OR = 1.76; 95% CI 1.11–2.8) or raloxifene (no controls exposed therefore OR was not calculated), exposure to alkylphenolic compounds (OR = 1.48; 95% CI 1.05–2.08), and presence of rosacea (OR = 1.91; 95% CI 1.07–3.39), lichen planus pigmentosus (LPP) (OR = 5.14; 95% CI 1.11–23.6) or hypothyroidism (OR = 1.73; 95% CI 1.11–2.69). For men, there was a statistical association between alopecia and use of facial sunscreens (OR = 11.6; 95% CI 1.7–80.9) or antiageing creams (OR = 1.84; 95% CI 1.04–3.23).
Conclusions
FFA seems to be associated with hormonal exposure (pregnancy, HRT and raloxifene), comorbidities (hypothyroidism, LPP and rosacea) and environmental factors (facial sunscreens, antiageing creams and occupational exposure). Further research is required to analyse the exact mechanism in which these environmental factors participate in the development of this alopecia.

Dutasteride has been proposed as an effective therapy for frontal fibrosing alopecia (FFA).
We sought to describe the therapeutic response to dutasteride and the most effective dosage in FFA compared ...with other therapeutic options or no treatment.
This was a retrospective observational study including patients with FFA with a minimum follow-up of 12 months. Therapeutic response was evaluated according to the stabilization of the hairline recession.
A total of 224 patients (222 females) with a median follow-up of 24 months (range 12-108 months) were included. The stabilization rate for the frontal, right, and left temporal regions after 12 months was 62%, 64%, and 62% in the dutasteride group (n = 148), 60%, 35%, and 35% with other systemic therapies (n = 20), and 30%, 41%, and 38% without systemic treatment (n = 56; P = .000, .006, and .006, respectively). Stabilization showed a statistically significant association with an increasing dose of dutasteride (88%, 91%, and 84% with a weekly treatment of 5 or 7 doses of 0.5 mg n = 32, P < .005). Dutasteride was well tolerated in all patients.
Limitations included the observational and retrospective design.
Oral dutasteride was the most effective therapy with a dose-dependent response for FFA in real clinical practice compared with other systemic therapies or no systemic treatment.
Androgenetic alopecia can be challenging to treat due to the wide range of available treatments, most of which are not based on evidence from clinical trials. In addition many of the options do not ...include androgenetic alopecia among the approved indications according to their summaries of product characteristics. A panel of 34 dermatologists from the Spanish Trichology Society of the Spanish Academy of Dermatology and Venereology (AEDV) used the Delphi method to develop a consensus statement on the management of androgenetic alopecia. Over a 2-round process the experts agreed on 138 (86%) of the 160 proposed items, which were structured into 4 blocks of recommendations: general considerations, pharmacologic treatment, procedures and hair transplant, and special cases. The resulting consensus statement based on expert opinion of the scientific evidence can guide professionals in the routine management of androgenetic alopecia.

El tratamiento de la alopecia androgénica (AGA) puede ser complejo para el clínico debido a la amplia gama de terapias disponibles, en muchos casos con escasos ensayos clínicos disponibles, y con muchas de las opciones de tratamiento sin aprobación de uso en la AGA según su ficha técnica. Este documento de consenso sobre el manejo de la AGA se ha elaborado siguiendo un método Delphi, en el que han participado 34 dermatólogos miembros del Grupo Español de Tricología de la Academia Española de Dermatología y Venereología. Tras 2 rondas de votaciones, se consensuaron 138 de los 160 ítems propuestos (86%), estructurados en 4 bloques de recomendaciones: generalidades, tratamiento farmacológico, procedimientos y trasplante capilar, y casos especiales. Este documento de consenso se apoya en la evidencia científica disponible y en la opinión de expertos para ayudar a los profesionales en el manejo de la AGA en la práctica clínica diaria.

Alopecia areata is an autoimmune disease that affects the hair follicle and can present as bald patches on the scalp and hair loss in other parts of the body. Diagnosis is clinical ...but can be aided by trichoscopy, a simple, rapid technique that reduces the need for invasive procedures and can also help with monitoring treatment response. We review the usefulness of trichoscopy in alopecia areata. The most common trichoscopic findings are yellow dots, black dots, exclamation mark hairs, short vellus hairs, and coudability hairs. Other, less common, findings can also help establish a diagnosis. Good response to treatment is indicated by the disappearance of black dots, broken hairs, and exclamation mark hairs. The observation of yellow dots, by contrast, indicates chronic disease and poor response to treatment.
La alopecia areata es una enfermedad autoinmune que afecta al folículo piloso. Se presenta en forma de placas alopécicas e incluso pérdida de pelo corporal. El diagnóstico es clínico. Sin embargo, la tricoscopia, una técnica valiosa no invasiva, simple y rápida, mejora el diagnóstico, la monitorización del tratamiento y reduce la necesidad de procedimientos invasivos. Realizaremos una descripción de la utilidad de la tricoscopia en la alopecia areata. Los hallazgos tricoscópicos más frecuentes de la alopecia areata son los puntos amarillos, los puntos negros, pelos en signo de exclamación, pelos vellosos cortos y pelos acodados. Sin embargo, existen otros hallazgos menos frecuentes pero útiles para realizar el diagnóstico. La buena respuesta al tratamiento implica la desaparición de los puntos negros, los pelos rotos y los pelos en signo de exclamación, pero la presencia de los puntos amarillos indica enfermedad crónica y mala respuesta.
