Topical dutasteride may have limited absorption due to its higher molecular mass compared to finasteride, potentially affecting its efficacy in suppressing DHT locally. Microneedling might enhance dutasteride absorption, possibly offering stronger local DHT suppression with fewer systemic effects.
The conversation discusses using propanediol as an alternative to glycerin in PG-free minoxidil for better absorption. The user also plans to try nanoxidil, which may absorb more easily due to its smaller molecule size.
The conversation discusses a prescribed hair loss treatment combining 12.5% minoxidil with tretinoin, azelaic acid, and topical finasteride, costing $55 a month. One user criticizes the packaging for degrading tretinoin, another suggests it's an overpriced option and recommends topical dutasteride as an alternative due to its higher molecular weight and lower systemic absorption.
User is on vacation in Greece and wants to buy tretinoin or isotretinoin to improve Minoxidil absorption. They are considering isotretinoin since it is available over-the-counter in Greece but requires a prescription back home.
