Folliculitis is the condition that specifically involves inflammation of the hair follicles. It occurs when the follicles become infected, which can lead to redness, swelling, and the formation of pus-filled lesions known as pustules. This condition is commonly caused by bacteria, such as Staphylococcus aureus, but can also be triggered by fungal infections, irritation from shaving, or blockage of the follicles.

The symptoms associated with folliculitis often include itching or tenderness at the site of infection, and these manifestations are direct results of the inflammatory response occurring in and around the hair follicles. The presence of pus indicates that the body is fighting off an infection, making this condition particularly recognizable compared to other dermatological conditions listed.

In contrast, psoriasis is a chronic autoimmune condition characterized by red, scaly patches but does not primarily affect hair follicles. Eczema is primarily associated with itchy, inflamed skin but also isn’t directly tied to hair follicle inflammation. Lichen planus is an inflammatory condition that affects the skin and mucous membranes but does not have a specific relation to hair follicle infections. Thus, folliculitis stands out as the answer due to its direct involvement with hair follicle inflammation and the possibility of pus formation.
