Infection and inflammation of the hair follicles. This is a relatively mild condition in which the hair follicle, the little sac of cells around the root of a strand of hair, becomes infected. The condition is called Folliculitis and can be caused by any sort of irritation to the hair or its root, whether physical or chemical. The follicle fills with pus and may manifest as a reddened pimple. It might itch slightly – more often, it is simply tender. These minor infections generally heal within a week or two.
Blemishes looking like burns. This is a rather serious infection, in which erupting blisters on the skin can erode the upper layers of the skin, leaving large patches that look like raw and reddened burn marks. This is an infection known as Scalded Skin Syndrome and is caused by Staphylococcal bacteria. The condition is most common among the very young, and when it occurs in a baby or a young child, it necessitates immediate medical attention.
