Make sure that your needs are matched to the therapists role of what you would like to achieve from the overall treatment. For example, what type of massage matches the results you are looking for.
If you are looking for Deep Tissue massage, tell your therapist what areas do you hold the most amount of tension and get your therapist to spend more time on these areas. It is always good to know what to expect beforehand, and that your therapist knows about your preferences and state of mind, stress levels, etc. before your treatment.
It is also important to complete a Massage Consultation Form prior to the massage treatment. You should always discuss with your therapist how deep you prefer the massage to be, depending on your stress levels and the amount of tension built up, as this would have an impact on the type of massage you do. You should also agree whether you would like massage oil in your hair or not, and similar details. Always talk to your therapist what is advised after your massage treatment.
