Noticed this and picked it up in act of 'oh what the hell'...haven't found much feedback at all online which is surprising as it's been out for a few years...although the lack of noise does suggest it's not all that great. But it's sold exclusively at Boots which in the UK is a respected pharmacy who also have their own hair retention programme, so you would hope they wouldn't stock any old crap...but then again, i did see the 'caffeine' shampoo next to it :/
Not sure whether to try it or get back my £30. I'll have a think over the next few days.
