What is henna commonly used for?

Henna is traditionally recognized for its ability to stain hair and nails, making it a popular natural dye. The leaves of the henna plant (Lawsonia inermis) contain a pigment called lawsone, which bonds with keratin in hair and skin to create a reddish-brown tint. This natural dye is often used in various cultural practices, particularly in South Asia and the Middle East, where henna is applied to hair for color enhancement and to create intricate designs on the hands and feet during celebrations such as weddings and festivals. Its effectiveness in coloring makes it a sought-after alternative to harsh chemical dyes in hair treatment, contributing to its widespread use in beauty and cosmetic applications.

The other options represent uses that are not typical for henna. While it is moisturizing for the hair, it does not serve primarily as a moisturizer for skin or a tool for skin exfoliation. Henna also does not have properties that promote hair straightening. Its main association remains firmly rooted in its ability to stain and color hair and nails.
