Stability Indicating Method Development and Validation of Finasteride by High-Performance Thin-Layer Chromatography Studies

Finasteride maintains its efficacy over time, slowing hair loss but not completely stopping it. Long-term users often experience stability, though natural aging may cause gradual decline; additional treatments like minoxidil, RU58841, and others may be needed for aggressive hair loss.

A 22-year-old male experiencing diffuse hair thinning has been using finasteride, initially at 0.5mg and then 1mg daily, but sees no improvement. Despite correcting a vitamin D deficiency and noticing some new hair growth, he questions the effectiveness of finasteride.

Finasteride may be losing effectiveness for the user after 4.5 years, possibly due to intense workouts or a synchronized hair shedding cycle. Suggestions include switching to Dutasteride or continuing with Finasteride while considering a hair transplant for hairline density.

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.

A 21-year-old is experiencing aggressive hair loss and questions the effectiveness of finasteride after 45 days of use, with high DHT levels. A user advises that scalp DHT, not serum DHT, is important for hair loss assessment, and suggests monitoring hair improvement over time.

A 26-year-old has been using finasteride for over two years, initially at 1.25mg daily and later at 5mg weekly, resulting in stable hair condition with some regrowth and minimal side effects. The user reports high libido and a protein and vegetable-heavy diet, with initial watery semen as the only side effect.
