There are a variety of products on the market to dye a beard or moustache, but the procedures involved are often the same. Some of the many popular men's hair colouring products include Just for Men, Grecian Formula and Grey Remover. Most grey facial hair can be covered by using a beard and moustache dying kit.
Purchase a beard and moustache dye kit. Read the box for instructions and match your desired hair colour with the colour on the box. Some brands show two or more optional colouring selections. Your moustache or beard should match the hair on your head. Do not assume that the instructions are exactly the same for every hair dye kit.
See if you have to mix. Many brands of beard and moustache dye require you to combine a colour with an activator. These should be mixed thoroughly for the dye to work. Wear the plastic gloves (they usually come with the kit) to protect your hands from staining. The mixture should be applied within 2 minutes after opening the tubes.
Apply the dye with the small brush that comes with the kit. Brush only your hair, not your skin. Hair dye is hard to remove once it dries. Brush from the roots and work to the tips of your hair.
Apply the mixture lightly since you can dye your moustache or beard again to darken the colour, but you can't lighten your hair once it's too dark. Apply the dye evenly to cover your entire beard or moustache. Your hair will darken more the longer you keep on the dye. Most dyes should be left on from 5 to 15 minutes. Check the instructions.
Rinse and dry your moustache or beard thoroughly. Discard the plastic gloves and rinse your mixing tray and brush. Clean any dye from your sink and counters. The dye can be difficult to remove it once it dries. If your hair is too light, try another hair dying session until you attain the shade you want.
Most men will need to dye their facial hair once every four weeks.
Hair dye contains harsh chemicals that can harm your hair.
