How long were you using minoxidil and how long ago have you stopped using it? For me it was almost exactly the same time as starting Trinov (couple of days overlap).Our situations are very similar. I'm a pattern diffuse thinner as well and I've been on trinov about 11 weeks. I've also noticed an uptick in shedding lately. Not nearly as bad as when I was shedding from stopping minoxidil or when I first started trinov but I'm back to a few too many hairs on my pillow and in the comb. I'm still committed to seeing through trinov for at least 6 months but, today at least, I'm not feeling terribly encouraged.
Even the crapola study sponsored by Fidia points to a cessation of hair loss, increased percentage of hair in anagen phase and, yes, even an increase of nearly 10% in hair diameter by the 6th month. At this point, even that would feel alright.
Also I don't think I experienced a shed from Trinov itself. Unless it's the one I'm having now. It's more likely to be caused by stopping minoxidil though.
Let's both hang in there!
