Does folliculitis have a cure? what is the best treatment for folliculitis in hair and beard (face)?

Need to examine: It is not feasible to provide a meaningful opinion without examining you and your symptoms warrant evaluation by a physician. You may visit this site for info and discuss it with your doctor. https://www.mayoclinic.org/diseases-conditions/folliculitis/symptoms-causes/syc-20361634

Folliculitis: For recurrent folliculitis, you can attempt decolonization of the bacteria on the skin. After a course of antibiotics, you can use a combination of hibiclens- wash 1-2 times per week and use mupirocin ointment twice a day to the inner nostril and under the finger nails. I agree with seeing your physician for evaluation.

Beard folliculitis: Wash your face twice daily with an antibacterial soap. Use a clean towel each time and pat face dry. Shave with an electric shaver. Shave in direction of hairs. Sterilize shaver after use. If red bumps and pimples are present a course of an antistaphyloccoal antibiotic like dicloxacillin(if you're not allergic to penicillin) should help. Discuss with your MD. See a dermatologist as needed.
