I’ve been on fin for 6 years. Want to switch to DUT

Hey guys, I’m 35 and I’ve been on finasteride and minoxidil foam for 6 years. I’ve responded very well as my crown was thinning and it filled it great and things have been good. I don’t know if I’m being paranoid or not but I think my crown is starting to thin again. Considering I’ve had no side effects from fin I would hope dut would not give me any side effects. Anyone made the switch? Did it help? Did it make things worse? I’m based in the U.K. thanks for reading
