In daily life, folliculitis can be a troublesome skin issue, especially in a humid environment like Hong Kong, where its occurrence is more frequent.
First, folliculitis can be considered a type of skin inflammation that is closely related to common acne. It usually manifests as small pustules or rashes on the skin, particularly when hair follicles are stimulated. In this process, microorganisms like bacteria and fungi present on the skin’s surface can also affect hair follicles, leading to more problems.
Folliculitis can be categorized into several different types, with the most common being bacterial folliculitis caused by Pseudomonas aeruginosa. Fungal folliculitis is also a common condition, characterized by relatively uniform size and noticeable itchiness. It is noteworthy that folliculitis can occur in areas of the body that are more humid and warm, such as the armpits, elbows, and behind the knees.
Regarding the causes of folliculitis, there are mainly three factors: First, a decline in local or systemic immunity, which can result from factors like staying up late, stress, and poor diet; second, blockage of the hair follicle’s opening, often caused by excessive sebaceous gland secretion; and third, excessive proliferation of local microorganisms. In this context, athletes or those who sweat frequently are particularly susceptible to folliculitis, as the humid environment provides a breeding ground for fungi.
Many people may experience folliculitis on their calves or beards, usually due to improper shaving techniques. Additionally, the use of certain hair gels or lotions may also lead to follicle blockage.
To effectively prevent folliculitis, doctors recommend avoiding tight clothing and opting for breathable fabrics. Moreover, it is essential to dry off and change clothes promptly after exercising to avoid prolonged exposure to moisture. For individuals who frequently experience folliculitis, using body washes and shampoos containing antibacterial or antifungal ingredients can significantly reduce unnecessary skin problems.
If folliculitis symptoms become severe, topical antibiotics or antifungal ointments may be used. Should the condition not improve, consulting a doctor for further treatment is necessary. Using exfoliating products containing alpha hydroxy acids or salicylic acid can also help reduce the occurrence of hair follicle blockage.
Finally, maintaining good lifestyle habits is crucial in preventing folliculitis. Ensuring adequate sleep, a healthy diet, and regular exercise can enhance the body’s resistance and reduce the risk of inflammation.
