Semi-permanent dye doesn’t completely cover grey hair in the same way that permanent dye does. Instead, it works to blend the grey with your natural hair color. This dye stains the grey hairs to make them appear highlighted against your natural color.

Your stylist will blend a shade just for you, so you’ll need to know how to replicate that color if you want your roots to match the rest of your hair. You can purchase dye treatments that are specifically designed for touching up the roots. Alternatively, you can use just a small amount of your regular hair dye.
