5 / 244 resultscommunity Everyone is ignoring that plasma finasteride levels are 100x lower with topical compared to oral.
Topical finasteride results in plasma levels 100 times lower than oral finasteride, potentially reducing systemic side effects. Users report similar efficacy with fewer side effects, suggesting a preference for topical application.
community Fin/Dut and Metabolism Speeds…
A user speculates that a fast metabolism might affect the effectiveness of dutasteride for hair loss. Another user argues that drug response is unrelated to metabolism speed.
community 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?
Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.
community Topical finasteride now the safest possible path?
Topical finasteride is considered a safer option for hair regrowth with fewer systemic side effects compared to oral finasteride. Some users report similar efficacy and side effects between topical and oral treatments, while others prefer topical due to reduced systemic exposure.
community Why is dutasteride's volume of distribution so much bigger than finasteride? Is it more lipophilic and crosses barriers better?
Dutasteride has a larger volume of distribution than finasteride due to its lipophilic nature, allowing it to concentrate in hydrophobic areas and making it difficult to excrete. A user experiencing hair loss has been using oral finasteride for 10 months with minimal regrowth and is considering switching to dutasteride or adding oral minoxidil.
