Henna has a history of use in body art for at least 5,000 years and has been influenced by migration and cultural interactions.
Some scholars suggest that the earliest documentation of henna use can be found in ancient Indian texts and images, indicating its possible origin in ancient India as an art form known as mehandi.
Initially, henna stains appear orange when the paste is removed, but they darken over the following three days due to oxidation, resulting in a deep reddish-brown color.
The thickest layers of skin on the soles and palms absorb the most lawsone from henna, resulting in the darkest and longest-lasting stains on hands and feet.
Once the henna stain reaches its peak color, it remains vibrant for a few days before gradually wearing off through exfoliation, typically within one to three weeks.
