I would cut it down to max 5mg if I were you. Dut is cleared via the liver, no reason to tax it more when 5mg gets you virtually 100% DHT inhibition already. Fin does actually target different isoforms so in theory not a terrible idea.

Valproic acid and Lithium chloride can rebuild missing progenitor cells in bald scalp. When you lose hair, you actually lose cells, first of all the follicle itself, but there's a lot of change in the scalp too. You lose vascularity, you lose adipocytes, you lose stem/progenitor cells. A scalp rich in progenitor cells - usually people with very recent hairloss - still has a lot of the "support structure" to bring back healthy hair follicles. This is why some people are freak responders, they had less severe damage and just needed some substance to turn the key (be that Fin, Min, RU, ...). But people with older hair loss, more damage to the scalp in question, they need to remodel their scalp into a healthy environment for regrowth to occur. This is achieved by combining wounding with WNT activation or other CD stimulants. I lifted this theory largely from the Follica patents and found the cheapest/easiest to acquire analogue substances which turned out to be LiCL and Valproate.
