Finasteride, a 5α-Reductase Inhibitor, Potentiates Antinociceptive Effects of Morphine, Prevents the Development of Morphine Tolerance and Attenuates Abstinence Behavior in the Rat

Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.

The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.

The user discovered their previous hair loss medication was counterfeit and switched to Propecia, which significantly lowered their DHT levels. They plan to continue using Propecia and add oral Minoxidil to their routine for better results.

Finasteride helps with hair loss by lowering DHT levels in the scalp, which is more important than blood DHT levels. If finasteride is not effective, consulting a doctor or considering switching to dutasteride may be advisable.

Finasteride is the most effective treatment for reducing DHT and addressing hair loss compared to fish oil and saw palmetto. Topical treatments like RU58841 and minoxidil are also discussed, but finasteride remains the most effective option.

A 25-year-old male experienced significant hair regrowth after one year of using 0.5mg daily finasteride, with plans to add 1.25mg oral minoxidil and microneedling for further improvement. He also uses Nizoral shampoo weekly and reports no current side effects.
