I have folliculitis on my back. Will IPL laser hair removal work to get rid of it? Any possible negative effects? (photo)

Antibiotics only work slightly and it comes back so I'm not sure what kind of folliculitis I have. There are no pustules and its only in areas I have shaved before. From what I've researched, I can not afford any therapy other than IPL. I'm sure the folliculitis in my scalp is bacterial so I'm not sure if that relates at all and I have dandruff but I use medicated shampoo. I have coarse dark hair and its pictured with my skin and the bumps won't go away for the treatment unfortunately.
