The henna stain would last anywhere between a few days to weeks, depending on the area where you are applying and the number of times you expose the area to water. The color then fades away gradually. For example:
- If you apply it on the back of the hands or tops of the feet, the color will last nearly 2 weeks but will fade away if you wash your hands a lot.
- If you apply it on the forehead, cheeks, noses, lips, ears, scalps, and necks, the stain will last a few days to a week.
- If you use it on the shoulder, chest, back, buttock, back, belly, and upper arm, the stain will last for 7-10 days.
- If you apply it on thighs, lower legs, and lower arms, the stains will last 10 days to 2 weeks.
The stains wouldn’t last long if you:
- Are elderly
- Swim frequently
- Exfoliate regularly
