The causes of vulvar folliculitis in women may be due to pathogenic bacterial infections, trauma, and factors such as hair plucking and wearing tight clothing. 1. Pathogenic bacterial infection: the most common pathogenic bacterial infection is Staphylococcus aureus, if the organism is infected by the pathogenic bacterium, it may lead to vulvar folliculitis. 2. Trauma: If a woman’s vulva is traumatized, it may cause germs to infect the lesions, which may lead to vulvar folliculitis. 3. Hair pulling: If the patient vigorously pulls or plucks the local hair, it may lead to damage to the hair follicles, thus triggering vulvar folliculitis. 4.

There are many reasons for women to suffer from folliculitis vulvae, so it is recommended to consult a doctor in a regular hospital to clarify the relevant issues.
