Which infection is commonly associated with improper waxing techniques?

Folliculitis is a skin condition characterized by inflammation of the hair follicles, often appearing as red bumps or pus-filled blisters. It is commonly associated with improper waxing techniques because the process of waxing can lead to trauma and irritation of the hair follicles. When the skin is not properly prepared or when the wax is applied or removed incorrectly, it can create an environment conducive to bacterial infection, resulting in folliculitis.

In contrast, athlete's foot is a fungal infection that typically affects the feet, while psoriasis is a chronic skin condition that leads to red, flaky patches. Nail fungus is a fungal infection that occurs in the nails and is not related to waxing practices. Each of these conditions arises from different causes and is not linked to the technique of hair removal, making folliculitis the most relevant answer in the context of improper waxing techniques.
