The following two main points should be noted for the thorough treatment of pediculosis: first, thoroughly kill the fungus, and second, pay attention to life care to avoid recurrence. For the first point, you should carefully observe whether the toenails of both feet have been involved, if the toenails have been involved, with a thickened, cloudy gray nail appearance, it is recommended to take oral itraconazole capsules or terbinafine tablets as early as possible and carry out systematic antifungal treatment, which can generally be completely cleared in 3-4 months. If the toenail is not yet invaded, only the skin can be treated. It is recommended to apply topical miconazole cream and boutinafine ointment once a day at night, alternately, for 3-4 weeks, and if the effect is not good, repeat the treatment once after an interval of 1-2 weeks. The second point, the main life is to wear breathable shoes, pay attention to personal hygiene, do not share bath towels, foot basin, etc. with others.
