Is it bad to stroke your beard?
While lightly stroking your facial hair won't typically cause a lot of damage, if you do it very often, especially in one area, it won't be long until you start pulling your hairs out. This may cause bald patches to appear on your face, and will ruin all your hard work in growing and maintaining your magnificent mane.
What stimulates beard growth?
You can stimulate your beard growth speed with things like proper nutrition, exercise, sleeping more, applying 3% dilution of peppermint oil to the face, trying Minoxidil for beard, improving cheek circulation, and through microneedling with a Derma Roller.
