I have been pleasantly surprised by this. I genuinely bought it safe in the knowledge that it has a great returns policy and, to be honest, thought I would be exercising my right to send this back after a couple of months. My husband has been using this, as instructed, and there has been definite improvement. His hair was only thinning and the progress is slow (although any faster and it may be a little alarming not to mention Wayne Rooney-esque) so don't expect miracles and I don't think it claims to bring back hair from the dead. He will persevere though so will write a follow up review if anything changes. For now, I am pleased we invested in this and at that price it is an investment. But like all investments they prove to be worthwhile if they deliver the dividends and this is yielding new hair!
