I dont know anything about the newest version of tricomin but from what I see in reviews its absolute garbage. It has really bad ratings, its more money and you get less. I used the first version i thought was great, second version still thought it was good, but admittedly after seeing all these new terrible reviews for this new one, and you can just see ingredient wise it has different stuff in it so you know something must have changed.
I know a lot of people here apparently think shampoos etc dont really matter from what I read but I can say for me personally. I have had a lot of health problems, and untill i started having all these lupus problems specifically(which now nothing seems to work no matter what I do and my hair just continues to thin)I had people that use to think I wore a wig. Sure I still had thin spots from where I had some cancer stuff taken out, and it had a natural wave to it when it grew back from radiation etc. But point is tricomin kept me having a lot of hair.
Ive used a lot of different shampoos, tested them, paul mitchell, some nioxin stuff, regenepure, 2% nizoral(ive actually though recently of maybe trying the 1% since 2 % was just to harsh for me made me shed but will see), blah blah... And at best the shampoos are just a cosmetic difference.. and by that I mean I can tell with in just one washing my hair "looks" thicker, but say in the shower and through out the day I notice me shedding more. But when I used tricomin, hair looks thicker, and its not shedding more. Which is one of the biggest differences i personally find with a lot of these so called volumizing shampoos etc, lose more hair while using them, but it just like coats your hair or something and it gives you a fake fullness if you will.
So in short ya I do think copper stuff works. Or at least the shampoo was good.
