Here's why:
* Henna is a natural dye: It stains the hair shaft with a reddish-brown pigment.
* It doesn't contain bleach: Henna doesn't have any ingredients that can strip the natural melanin from your hair, which is what causes lightening.
While henna can create the illusion of lighter hair by adding a reddish-brown hue, it won't actually change your hair's natural color.
Important Note: If you have previously used chemical dyes, henna can interact with them in unpredictable ways, potentially leading to unwanted color changes.
