But whether you’re a hair dyeing fanatic or a newbie, it’s always best to learn proper techniques to dye your hair safely. In this article, we’re going to tackle how long to leave hair dye in your hair, whether it’s a permanent or semi-permanent dye.

How long to leave hair dye on roots?Whether you’re touching up your roots or doing an all-over color, the hair on your roots processes differently compared to the rest of your hair. That’s because the hair on your roots is healthier compared to the mid-length and ends of your hair since it hasn’t been exposed to UV, heat, or chemicals as much as the rest of your hair. So it’s recommended to leave the hair dye in for a few extra minutes as it takes the hair dye longer to penetrate your hair shaft. If the label on the box says to leave it on for 20 minutes, add an extra 10 minutes. Also, if you’re doing an all-over color, make sure to apply hair dye on your roots last to avoid hot roots, as the heat from your head will make the dyeing process faster.
