I just found out that a client I massaged on Saturday rang the clinc to ask what oil I had used as she had had an allergic reaction. I normally use organic sunflower oil for my masages but I ran out and so used my colleagues grapeseed oil. This was a new client and I've never had anyone say they've had a reaction to the oil. This would have spoiled her masage experience and so I feel bad about it. Has this happened to anyone else. I'm looking online to see what can be done about it. I don't know what symptoms she had but I'll call the clinic to see if she expalined how her skin was. Note to self - make sure you don't run out your own oil.
