After treatment for folliculitis, if the affected area feels completely flat when touched by hand, without any protruding or proliferative hard nodules, or red bumps, and lacks any pustule-like papules, it is generally considered to be healed.

However, even though the condition has healed, it cannot be completely eradicated and there is still a risk of recurrence. It is crucial to avoid spicy and irritating foods long-term, try not to stay up late, engage in regular exercise, sweat more, bathe more frequently, and avoid soaking in public baths or swimming to reduce the possibility of bacterial infections. Also, avoid consuming spicy, greasy, or sweet foods as they can increase internal heat and dampness in the body, potentially exacerbating folliculitis. Therefore, once this condition occurs, it is essential to undergo standardized treatment.
