Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.
Finasteride reduces scalp DHT significantly even at low doses, with 0.2 mg reducing it by about 55%, but higher doses like 1 mg and 5 mg offer only marginally more reduction. Users discuss side effects, with some experiencing none and others reporting issues like low libido, and they also mention using other treatments like minoxidil and dutasteride.
The conversation discusses using different concentrations of topical treatments for hair loss, specifically Minoxidil, Finasteride, Dutasteride, and Tretinoin. The user is considering higher concentrations after previous treatments were ineffective.
Minoxidil can initially cause hair shedding but often leads to increased hair count over time, with some users experiencing noticeable improvements within weeks. Combining Minoxidil with Finasteride may enhance hair health, though individual results vary.
Finasteride is prescribed at 1mg because it is FDA-approved and proven effective, despite evidence that 0.2mg may similarly reduce DHT. The 1mg dose is more effective for hair growth, and lower doses are less available.
Finasteride and dutasteride can show initial hair count increases within 12 weeks, but visible improvements often take longer, with many users reporting noticeable changes after a year or more. While early results may be seen under a microscope, significant cosmetic improvements typically require more time for hair to thicken and become visibly denser.
