White vinegar is an effective home remedy for folliculitis. White vinegar is very cheap and available in grocery stores everywhere. White vinegar can be applied to the infected areas with cotton balls. It can also be added to a spray bottle for easy application to a larger area of infection.
White vinegar is strong and may burn if you have broken skin. In this case, dilute the vinegar with water, using equal parts of vinegar and water. If this solution still stings, you can follow up your vinegar treatment with castor oil or coconut oil, two oils that are also healing to folliculitis.
