How Do I Remove Semi Permanent Dye From My Scalp And Face?
May be you should wash lt off
Next time apply conditioner to the area around your hairline and on your part to prevent this mishap. It comes off eventually like marker does.
Try using a little hair dye on a damp rag. Rub it in and then rinse. Next time put some cream or conditioner around your face and it will prevent the dye from soaking into your skin.
Try perming lotion ( any brand ). Squeeze the perming lotion on your scalp and massage gentle for a few minutes then rinse thoroughly .It might bleach a little of your coloured hair. I myself had tried and it worked.
