Yes, I'm using Folligen and minoxidil at the same time. I usually apply them within minutes of each other.
I started Tricomin and minoxidil at the same time, in August. I started dutasteride later. My regrowth was noticeable (to me) after about three months of using minoxidil and Tricomin, and I have been using Folligen only for the last month or so, and the Lasercomb for only the last few weeks. Regrowth seems to be picking up steam now, I'm even getting some along my hairline, but my earliest regrowth occured before dutasteride would have had a chance to be effective. I attribute it to the Tricomin and minoxidil. The reason I think that Tricomin played at least a role in it is because I've been using Pickart's CP Serum on my face, and as I mentioned in another thread, recently I have noticed that my beard is starting to come in a bit thicker. So apparently for me anyway copper peptides are acting as a regrowth agent.
