Shocking Folliculitis Pictures
Fungal & Bacterial Infected Follicles
The infection can be in the whole follicle (deep) or just a part (superficial) of the follicle.
When you look at the folliculitis pictures (by following the links) it is very easy to see where the superficial and where the deep infections are.
I must stress that an ingrown hair and folliculitis is not the same thing, because infection is absent with ingrown hair.
An ingrown hair can be a little red and swollen, because the follicle is irritated. There can even be a little inflammation. Folliculitis is serious, because infection by fungus or bacteria is present.
