For long term results we advise clients to do a course of 15-20 salt therapy sessions. The sessions should be frequent; about three a week is suggested. With irreversible conditions you may need to come for more sessions.
In most patients, after a course of Salt Therapy, airways become normal and symptoms disappear. The treatment's efficacy is estimated at 75-98%. Most clients do 1-2 Salt Therapy courses a year. In between they might come back for some top-up sessions, if they start to feel poorly, e.g. they are coming down with a cold.
