Why is my older Brow Henna much darker?Updated a day ago

Once the jar has been opened, the henna comes into contact with oxygen. Over time, this causes the powder to become darker due to a natural oxidation process.

This does not affect the final colour on the brows. The result will not be darker than with a freshly opened jar.

However, the performance of the henna may gradually decrease over time. For the most consistent results, we recommend using opened henna within 6 months.
