Thoughts On Adding Topical Fin/Min Spray To Oral Dut?

Currently take oral dut and topical min. The Hims spray has fin as well as 6% min (which is another bonus). I have very aggressive loss and am aiming to get a transplant this year but want to maximize any potential regrowth first.

Would topical fin help reduce more scalp DHT even if I’m already on dut? And would the 6% min be noticeably more effective than 5%?
