Watched the live. Lots of shouting about 'qualifications', without specifying what those are or what people should be looking for. Bellowing about needle length, whilst forgetting that their line between acceptable and not acceptable is a quarter of a millimetre, as if that's going to make much difference. Lots of patronising comments about things being very scientific and difficult to explain, without considering that their audience might actually be intelligent and/or professional and perfectly able to understand it. Lots of overlap between who wouldn't use it and who should, which made no sense. Generally lots of fear around grown woman being able to make their own active choices rather than listen to 'professionals'. So far, so beauty industry.
If Hirons hadn't been in such a hurry to trash Trinny, she could have turned this into a really useful live. She could have called in all the home kits, talked about the pros and cons, how to do it, and then talked about what you get with a salon treatment that you can't get at home, and whether it's worth the outlay on a home kit or save it to spend in a salon.
