Henna Tattoo Chemistry
One can avoid this part by re-coating the design again with mehendi as sugar and lemon syrup makes the palms stickier creating other possible problems. The mehandi is worn three to six hours, or sometimes kept overnight and then removed by simply with the fingers. When first removed, the henna design is pale to dark orange in colour and gradually darkens the colour within the next 24 to 72 hours. This final reddish brown colour can stay on hands or feet from one to three weeks depending on the quality and type of henna paste applied.
