GC Determination of Eleven Kinds of Residual Solvents in Finasteride

The conversation discusses the potential use of HMI 115 for hair loss and whether it could replace or be used alongside finasteride, minoxidil, and RU58841. The user is experiencing scalp inflammation and continued hair shedding despite using finasteride for 8 years.

A user is making a homemade topical finasteride solution by dissolving crushed finasteride tablets in ethanol and PG. They are unsure if the final solution maintains the intended concentration after filtering and are considering adding more ethanol to ensure accuracy.

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

OP asked if a product from Amazon is sufficient to dilute finasteride. A user advised against using propylene glycol alone, suggesting a pre-made solution instead.

The user experienced persistent acne and skin issues with dutasteride, leading them to stop its use. They switched to finasteride, which caused mild acne and potential liver concerns, prompting consideration of alternative treatments like topical finasteride and GHK-Cu.

Finasteride pills don't fully dissolve in a DIY topical solution due to fillers, resulting in residue. Users suggest shaking well before application and note that commercial solutions appear clearer.
