Fillers Impacting Follicles: The Emerging Complication of Filler-Induced Alopecia

The document reviews the emerging complication of filler-induced alopecia, highlighting cases where dermal fillers such as hyaluronic acid, autologous fat, and calcium hydroxylapatite have led to hair loss, primarily due to vascular compromise. It presents detailed case reports and emphasizes the importance of early intervention and precise management to prevent permanent hair loss. Treatments like hyaluronidase, minoxidil, PRP, and topical recombinant bFGF have shown benefits, with hair regrowth observed within 2-3 months in some cases. The review underscores the need for thorough patient assessment, anatomical knowledge, and careful injection techniques to minimize risks, while also calling for further research to validate treatment protocols and optimize injection techniques.
