In case your clothes get stained with henna, you don’t have to worry about the fading of the fabric colour. Just follow this step-by-step process; it’s tried and tested.
Cold water. Treat the stains with cold water nicely and then rub them with some dishwash liquid on both sides.
Pour some vinegar over the stains and rub it with your finger. Let it sit for 2 hours.
Add a few drops of hydrogen peroxide to the stain on your clothes. Be careful when adding peroxide to your clothes as it can bleach the fabric.
If you can still see traces of stains, treat them with some rubbing alcohol.
Let the clothes air dry and put the garment to wash in the machine.
