Many men, especially men with frizzy or curly hair, suffer from ingrown beard hairs.
To prevent ingrown hairs, do not shave the beard hairs too short.
Do not put too much pressure on the razor while shaving. Too much pressure can cause the beard hairs to be shaved too short.
If necessary, shave with a safety razor instead of a modern cartridge multi-blade razor.
Do not shave every day, but every other day.
Only shave in the direction of the beard hair growth. Do not shave against the direction of hair growth.
Cleanse the skin before shaving with an exfoliating cleansing gel.
If necessary, use special exfoliating creams that can prevent ingrown hairs.
