Dutasteride might be better for hairline due to varying levels of 5AR activity in scalps. Genetic tests can determine if finasteride is enough or if dutasteride is needed.
Asteride into your routine
In this conversation, the user Icy-Indication267 was asking when they should start finasteride to treat their hair loss, which had responded well to minoxidil after two months. Other users shared advice on incorporating micro-needling and topical finasteride into their routine for optimal results.
Hair loss treatments, specifically the use of Alfatradiol as an over-the-counter topical 5AR inhibitor that has been shown to be effective in stopping hair loss without side effects. Other treatments discussed include Minoxidil, finasteride and RU58841.
Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.
Hair loss treatments, specifically 5AR inhibitors, can impact neurosteroids and sexual health. The effects of topical fin/dut on tissue-specific DHT levels are unclear.
