I thought the same thing - however I said what the heck I will give it a try lipogaine, microneedle and regenepure. It has been just over 2 months and I can tell you that when I shampoo there is maybe 2-3 hairs in my hand v.s. have over 15 prior to me starting.
I really believe the microneedle and lipogaine work (check out the ingredients of lipogaine impressive). But I too wondered/wonder if he is paid - regardless what he is saying works.
Also some other reviews are negative - he rates regenepure much better than revita. And has some negative things to say about other products.
