The document reviews the mechanisms and treatments for non-scarring alopecia, focusing on conditions like androgenetic alopecia, alopecia areata, and trichotillomania. It highlights FDA-approved treatments such as minoxidil, finasteride, ritlecitinib, and baricitinib, noting their varying effectiveness and side effects. The paper emphasizes the need for new treatments due to the multifactorial nature of alopecia and the limitations of existing therapies. It underscores the importance of understanding the complex interplay of factors contributing to non-cicatricial alopecia to improve therapeutic interventions. The document also discusses the potential of personalized treatment approaches and the integration of traditional and modern methods, highlighting the necessity for more real-world data and longitudinal studies to evaluate the safety and efficacy of these emerging treatments.
