By contrast, stem and leaf hairs can be unicellular or multicellular. Root hairs of older portions of roots are destroyed over time, and only at a certain region near a growing apex (called the root-hair-region) are root hairs seen. Although microscopic, root-hairs can be observed by the unaided eye in chili and Brassica seedlings.

Contact with the eye can cause considerable destruction and with the mouth a rash, swelling, and peeling of the skin.
