That’s fair enough. Sometimes you have to weigh the risks and decide to go for it or don’t. I think what can help your case is really understanding why it happened. That’s why I think attacking hair loss using a different mechanism is worthwhile. You had a bad reaction to lower dht, so maybe don’t lower dht at all, but block androgens from reaching the receptor at all.
RU is dose dependent too, so the more you use the more it blocks. The good thing about this in your case is it your hyperandrogenicity acts up, you can increase the RU dose to counteract it. I’m not entirely sure, but I’d imagine there’s a natural limit to how much your body can upregulate sensitivity and it falls short of exogenous AR blocking.
I think in your case it’s your scalp undergoing shedding because of the inconsistent use of finasteride. Once your body hormones stabilize, your shedding should go down and the oiliness would go away too. Topical probably goes into the system slower too. September 1st is around 3 months ago so I’d imagine your shedding and hair should stabilize soon. Topical dutasteride is apparently really good for a once in a week type deal. It has a long half life in tissue so it doesn’t need to be as frequent
