I was approached a couple of years ago by a guy who wanted to "train me up" (over Skype!) so I could start doing teeth whitening. He has beauticians hosting teeth whitening parties for him and he takes a % of the profits (!?!) At the time I didn't know anything about it (and certainly didn't know it was illegal !) but when I looked into it I was horrified at the prospect of me being let loose on someone's teeth with a load of chemicals. It's kind of up there with me starting to offer Botox parties after a quick demo via You Tube. This guy is still going strong in the UK and has no shortage of customers ready & willing to pay (very little) for sparkly white teeth. No thanks! x
