The risk of acquiring plant-related dermatitis is influenced by host susceptibility and exposure. Impairment in the barrier function of the skin may increase the propensity for sensitization. Chronically immersed hands (eg, florists' hands) may be particularly predisposed to plant-related dermatitis.

Allergic contact dermatitis requires exposure and sensitization to the causative plant products. In patch-testing conditions, more than 70% of the population in the United States reacts to poison ivy and poison oak allergens, whereas roughly 50% of the population has such reactions in nature.
