When you come to your initial Patch Test appointment you should be sure to do the following things:
Bring with you a list of any medication(s) you may be taking including herbal supplements
Print a map for the designated centre so that you are able to find it and reach your appointment on time
Leave the area to be treated in its natural state (IE do not shave, wax, pluck or remove the hair) prior to the session as the practitioner will need to see this area in order to assess it fully.
