I would like to know what you thing about a bleach bath for a fungi on my back back . i have tried different fungus?

I don't recommend it: Bleach baths with a very small amount of bleach (no more than 1/2 cup of bleach to a full bathtub). However, they are typically used for eczema and bacterial infections. Also, even at at such a weak strength it can cause irritation in some people. I recommend seeing a local medical provider for medication.

Antifungal : Low concentration bleach baths can sometimes help people with eczema. With a fungal infection such as tinea corporis or yeast such as tinea versicolor, see a dermatologist. They may do a culture or scraping to identify the type of organism and then give you oral and/or topical treatment.
