A. Hair pulling in babies can be due to curiosity, self-soothing, or a disorder called Trichotillomania (baby trich). Pica is a disorder where children persistently eat non-food items, including hair, which can be dangerous. Toddlers might pull hair to express anger or frustration, or as a learned behavior from others.
