I currently have Folliculitis and am taking antibiotics.
My skin is uber sensitive naturally, and therefore I venture to propose my infection resulted from infected razor burn
even after Brazilian waxing.If you still want to go in for Brazilian waxing ,then apply cold compresses(ice cubes wrapped in a towel) on the rash and take some antihistaminic like benadryl or claritin.You can also apply calamine lotion on the rash.It will help in soothing the skin.A mild corticosteroid cream like dermacort will also help.
Also you can go in for laser hair removal which causes permanent reduction of hair and does not cause folliculitis also.Pls consult a good cosmetologist/dermatologist for that.
Hope it helps.Take care and pls do keep me posted if you have any additional doubts.Kind regards.
