There’s no reason to believe that online hypnotherapy does not work better than face to face hypnosis.
In fact I have found that many of my clients prefer having their session in the comfort of their own home. Being in your own surroundings is often a relaxing experience and that’s a perfect environment for change to happen.
E-therapy has already had many academic articles published, a quick search on Google Scholar shows many trials have been running for over a decade. The results state that not only is online therapy as effective as other methods but it’s more accessible. People with mobility issues, social anxiety, agoraphobia and rural communities all benefit.
