Inflammation of the hair follicle, or folliculitis, can interfere with the normal growth of the hair and lead to hair loss. Folliculitis is usually caused by an infection or irritation of the hair follicle and can be caused by a variety of factors, including bacteria, fungi, and irritation from certain hair products. In some cases, folliculitis can lead to scarring of the hair follicle, which can interfere with the growth of the hair and cause permanent hair loss. Treatment for folliculitis may involve antibiotics or other medications to clear the infection and reduce inflammation, as well as topical products to soothe the scalp and reduce irritation. It is important to speak with a healthcare professional for a proper diagnosis and treatment plan.
