What is the best topical Dutasteride for hair that is commercially available? I’d like to try a non-systemic treatment. Is there a certain Dutasteride concentration that I should look for in the formulation or do I need to find a compounding pharmacy? I appreciate all feedback 🫡

I stopped all testosterone (TRT) about a year ago to get ahold of my hair loss and stabilize everything. My DHT was high even though I was taking Saw Palmetto, Pumpkin seed oil and stinging nettles. Everything is now stable and I'm taking 1.25mg of oral Minoxidil but I'd like to resume some type of testosterone supplementation. My DHT is around 80-90 (ng/dl) when taking testosterone or enclomiphene and around 18-20 (ng/dl) without anything. Is finasteride the only option to reduce my DHT if the natural supplements aren't doing enough? What DHT level should I target? I appreciate all comments and feedback.
