PFB occurs when the hair grows out of the skin and then pierces and reenters the skin. To keep the hair from reentering the skin, you need to keep it from growing out, daily shaving is the best treatment.
According to Dr. Milton, PFB affects 60% of young black men and 10% to 15% of of white men.
Many people get an ingrown hair and quit shaving because they don't want to cut themselves when they shave. The key is to stay ahead of the growth by shaving DAILY. You can read the full article at Skin and Allergy News.
What was not mentioned in the article is that quite a few women can suffer from razor burn, whether that is in the unmentionable regions of their bodies (think brazilian) or legs.
What's a post on this blog without mentioning retinoids? One esthetician passed on this tidbit of information, she advisers her waxing clients to apply a retinol product on the ingrown hairs and the hair will pop out after a few days.
I know from personal experience that whenever I get an ingrown hair on my face, because of my daily use of a retinol product (and shaving), that the hair will unstick itself after a day or two.
