How long does Henna Hair Dye last? Henna Hair Color is a semi-permanent dye and gradually wears off over a period of approximately 8 to 12 weeks. This time period usually coincides with new hair growth, meaning that your roots will match your henna hair color for a nice, even coat most of the time.
You can find henna supplies at your local Indian or Middle Eastern grocery store. However, henna is perishable (its powdered dried plant leaves), and if it's been sitting on the shelf a long time, it may have lost it's dye strength. It might never have been good in the first place.ou just can't tell by looking at the powder what the stain is going to be like. If you want to know if your henna is dyed green to make it look good, mix henna with lemon juice and put it between two sheets of glass and leave it there for 15 minutes or so.
