Filler-Induced Alopecia

The letter to the editor discussed cases of alopecia induced by dermal fillers. The authors from the Department of Dermatology at Pusan National University in Busan, Korea, highlighted instances where patients experienced hair loss following filler injections. The letter emphasized the need for dermatologists to be aware of this potential side effect and to consider it when diagnosing and treating patients who have undergone filler procedures. The authors called for further research to understand the mechanisms behind filler-induced alopecia and to develop strategies to prevent it.
