Current and future treatments of alopecia areata and trichotillomania in children.

INTRODUCTION: Treatment options for hair disorders are generally very limited. These options are even more limited in children due to the lack of trials and clinical research. Moreover, physicians are sometimes scared to treat children with drugs without safety data, especially because most hair disorders are benign. AREAS COVERED: The objective of this paper is to review current and future treatments for alopecia areata and trichotillomania, two disorders that are sometimes encountered in differential diagnosis or even occur together and probably affect the mental condition of the patient involved more than others. EXPERT OPINION: Hair disorders are very stressful in paediatric population. Both physicians and families are often unsatisfied leading to non-compliance. New drugs with less side- effects are needed to increase the percentage of cure. It is also crucial to refine genetic studies on alopecia areata in order to identify new potential drugs worth studying. Moreover, studies on trichotillomania should not be evaluated only by psychiatrics, but also by dermatologists.
