Recent modalities in treatment of telogen effluvium: Comparative study.

Telogen effluvium is one of the most common forms of diffuse, non-scarring hair loss for which patients present for clinical evaluation. It is usually a reactive and reversible disorder. Identifying and correcting the underlying cause is the most important component in management, yet there is always a need for therapeutic options. This study aims to evaluate the efficacy of single session botulinum toxin A injection versus multiple sessions of multivitamins mesotherapy in the treatment of telogen effluvium. A randomized clinical trial was conducted in the Dermatology, Venereology, and Andrology Department, Faculty of Medicine, Zagazig University Hospitals. Twenty-four patients with telogen effluvium were randomly divided into two groups each group included 12 patients. Group I received a single session of Botulinum toxin A injection and group II received multiple sessions of multivitamins mesotherapy injection. Both botulinum toxin A and multivitamins mesotherapy are effective in the treatment of telogen effluvium, which was reflected on the improvement of hair parameters as terminal hair and multiple follicular units. Both treatment modalities had minimal and well-tolerated side effects. Although both therapies have equivalent success rates, single session of botulinum toxin A is a better choice than multiple mesotherapy sessions.
