It will vary on what you want to achieve. Some conditions can be healed in one session and others may take 2 or 3. The therapist that you see can advise you at your first treatment.
The time between treatments will vary according to the corrections that have been made and can be anything from one to six weeks. Sometimes only one healing session is required to heal problems such as food intolerances, allergies etc. and no repeat visit is necessary.
Clients have found it very useful to have a regular annual MOT to clear potential problems before they lead to physical difficulty.
