Follow the instructions on the box. Do not rinse the dye out before the minimum time or leave the dye in past the maximum time. Make sure to follow the directions exactly. If you have a lot of grey hair, it’s best to leave the dye in for the maximum amount of time. It may help to sit under a heated dryer, as well. Never leave hair dye in overnight. Leaving it in overnight will dry out your hair and it may cause severe skin irritation as well.
