Finasteride / Dutasteride vs Myo-Inositol (+ D-Chiro)
Both are used for skin & hair. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Finasteride / Dutasteride | Myo-Inositol (+ D-Chiro) | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★☆ |
| Legal status | FDA Approved | OTC Supplement |
| How it works | Inhibit 5α-reductase (SRD5A2), blocking testosterone→DHT conversion. DHT drives male-pattern hair loss and prostate growth. Finasteride hits type II; dutasteride hits I and II. | Insulin second-messenger; the 40:1 myo:D-chiro ratio improves ovarian insulin signalling, restoring ovulation and lowering androgens in PCOS. |
| In plain English | Testosterone gets converted into a stronger cousin (DHT) that kills scalp follicles. These drugs block that conversion to save hair — but for a minority, lowering DHT dents libido/mood ("post-finasteride" concerns). | Improves how ovaries respond to insulin — one of the best-evidenced natural treatments for PCOS (irregular cycles, acne, unwanted hair). |
| Bottom line | Most effective hair-loss drug; weigh the sexual-side-effect risk honestly. | — |
| Availability | Available over the counter | Available over the counter |
