Natural henna stains vary greatly depending on the skin thickness and location, body chemistry and other factors. Here, Audrey is wearing natural henna on her palms. The deep rich stain is typical on palms because of warmth & thicker skin layers. Henna paste was applied and remained on the palms overnight. This stain is 24 hours old, typical stain development takes between 24-48 hours. (Photo by Kimberly Teichrow Photography, Henna design & application by Allison Dickerson, Allura Henna).
