Make the grey hairs in your beard disappear in five minutes with the Just For Men M45 beard colour. This dark brown dye is formulated for facial hair, which is coarser than the hair on your head. It gives the beard a thicker, more even look.
Application is simple. Mix the colour base and the developer, apply with the brush supplied, then wait five minutes. Rinse and wash with shampoo. The formula contains biotin, aloe and coconut oil. This Just For Men beard colour suits the beard, moustache, goatee and sideburns.
One box allows up to three applications, depending on the length of the beard. If you are unsure about the shade, the brand advises choosing a lighter one. Always do an allergy test 48 hours before each application, as the manufacturer requires, and wear the gloves supplied. This men’s beard colour generally lasts three to four weeks.

Where we lean: for a man who wants to erase his grey hairs in a few minutes, this is a fast, well-known beard colour. If you want a single product for hair and beard, the Hairgum No. 3 below colours both. For other shades, browse our men’s and beard colour.
