learn Finasteride

Are there really risks with topical finasteride? Reports on topical finasteride describe scalp irritation and dermatitis as the effects specific to it, and blood levels lower than the oral drug; whether systemic side effects are genuinely rarer has not been measured in a trial powered to answer it. Both forms are prescription-only and contraindicated around pregnancy.
Topical or oral? Choosing between pills and lotions according to your case. Topical finasteride offers localized treatment with fewer systemic side effects than oral finasteride.
Do you want finasteride to penetrate better? The ideal solvent to maximize its effect. Formulation sources describe propylene glycol and microemulsion vehicles as increasing how much topical finasteride crosses the skin, but better penetration has not been shown to mean better hair results, and it also raises systemic exposure. The vehicle and strength are decisions for a prescriber or compounding pharmacist.

learn Bicalutamide

Is topical bicalutamide a safer alternative to finasteride? There is no published human trial of topical bicalutamide for hair loss, and no licensed topical product exists, so it cannot be called safer than finasteride — or shown to work at all. Oral finasteride has decades of trial data with a documented side-effect profile, and topical finasteride has a phase III trial behind it.

learn Fluridil

How is Fluridil different from other DHT blockers like finasteride? Fluridil is a topical androgen-receptor blocker applied to the scalp, while finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT throughout the body. Finasteride is FDA-approved and far better studied; Fluridil rests on one 43-man trial and is not licensed as a hair-loss medicine, so its long-term safety and effect size are unknown.
