Is there no way to cure athlete's foot?

My husband has athlete's foot.

It doesn't seem to be excessively itchy or anything.

My toenail has become deformed. Sometimes the color is abnormal.

It also looks distorted.

The soles of my feet are constantly shedding dead skin and look dirty.

They buy and use various antifungal medicines from the pharmacy.

It seems they don't completely disappear.

Will there be better medication if I visit the dermatology clinic?

If there is any medication sold at the pharmacy that has shown a complete cure effect,

Please recommend something~

Oh. And is athlete's foot contagious?

There are no problems with me and the children.

Sometimes, when I'm in a hurry, I even go out wearing my husband's slippers, haha.
