Objective:

To explore the therapeutic potential of intradermal botulinum toxin type A (BTA) for trichodynia unresponsive to conventional therapies in patients with different hair loss conditions.

Approach:
  • Study Design: A retrospective study assessing the effectiveness and safety of intradermal BTA in patients with trichodynia associated with hair disorders.
  • Patient Selection: Patients who declined or discontinued systemic oral therapies for symptomatic control were included.
  • Treatment Administration: BTA was administered as off-label therapy via intradermal injections using the Nappage technique.
Key Findings:
  • Intradermal BTA demonstrated rapid, significant, and sustained reduction of trichodynia severity in patients with cicatricial alopecias.
  • Minimal adverse effects were reported in patients treated with BTA.
Interpretation:

Limitations:
  • The study is retrospective, which may introduce bias.
  • The sample size and diversity of hair loss conditions were not specified.
Conclusion:
