title: Neem oil: an herbal therapy for alopecia causes dermatitis.
abstract: For more than 2,000 years, the neem tree has been considered one of the most useful and versatile plants in the world. Neem oil has been used for both homeopathic remedies and as a pesticide. Both systemic and contact reactions have occurred with the use of neem oil. We report a patient who presented with an acute case of contact dermatitis on the scalp and face after the use of neem oil for alopecia and present a review of the literature regarding its uses, toxicity, and regulation.
