Which more effective: topical finasteride/dutasteride vs oral Finasteride/dutasteride?

Question

Hello, Hair loss expert Doctors. What is more effective for treating androgenetic alopecia in males. Oral versions of finasteride/dutasteride or the topical versions of finasteride/dutasteride?

Audrey G. Bauer, MD · Answer

The improvement seen with topical DHT blockers was similar but with lower serum concentrations of medications seen in the group using topicals. Hope this helps

Jeff Donovan, MD, PhD · Answer

Thanks for the question. It depends on the dose. There are 3000 different versions and formulas of topical finasteride so it’s important to state which one you are referring to. Some formulas of topical finasteride and dutasteride probably work much worse than oral finasteride and dutasteride. Others are likely pretty similar. I see some formulas of topical finasteride with 0.01 %. I doubt these are as effective as 1 mg. I see some formulas where the finasteride seems to be coming out of solution in the bottle. I doubt these are as effective. In summary, there is no such thing as “standard topical finasteride.” Everyone makes it up differently. One is making a big mistake to assume all formulas of topical finasteride and dutasteride are the same effectiveness and one is making  a big mistake to assume all have the same side effects.
