β-agonists are prohibited substances for athletes according to the World Anti-Doping Agency and are banned as growth promoters for livestock in most countries. The illicit use of β-agonists is a significant concern for both human and animal health. Hair analysis serves as a valuable material for monitoring the abuse of β-agonists. This manuscript aims to provide a comprehensive overview of the application of hair analysis in monitoring β-agonist abuse. The morphology, structures, and composition of hair are summarized, along with an introduction to the mechanisms of β-agonist incorporation into hair. Considering various factors, the treatment procedures for β-agonist detection in hair, with special attention to the authentic matrix, are outlined. Additionally, diverse screening and confirmatory methods are reviewed. Particular emphasis is placed on novel purification processes and innovative analytical technologies employed for the analysis of β-agonists in hair.

This subgroup analysis of the ALLEGRO phase 2b/3 study (NCT3732807) assessed the efficacy and safety of multiple doses of ritlecitinib, an oral JAK3/TEC family kinase inhibitor, in Asian patients with alopecia areata (AA). Patients aged ≥12 years with AA and ≥50% scalp hair loss received once-daily ritlecitinib 50 or 30 mg (with or without 4-week 200-mg loading dose ["200/50" or "200/30"]) or 10 mg or placebo for 24 weeks, followed by a 24-week extension, in which patients initially assigned to placebo switched to 200/50 or 50 mg. In this subgroup analysis, Asian patients with response based on achieving a Severity of Alopecia Tool (SALT) score ≤20, SALT ≤10, ≥2-grade improvement or normal score on the eyebrow assessment (EBA) scale, and ≥2-grade improvement or normal score on the eyelash assessment (ELA) scale were evaluated through week 48.
