About Dutas 0.5 mg
Dutas 0.5 mg contains dutasteride, a medication that lowers dihydrotestosterone (DHT). Because DHT is a key driver of follicle miniaturization in androgenetic alopecia, dutasteride is sometimes used under clinician supervision to help slow hair loss and support thicker-looking hair over time. Availability may vary by country and pharmacy, and it is typically dispensed only under the direction of a licensed clinician.
Uses (hair-first)
| Use | Notes |
|---|---|
| Androgenetic alopecia (pattern hair loss) | Often used under clinician direction (off-label in many regions) |
| BPH (listed last) | Enlarged prostate; also an approved/common use in many countries |
How it works (simple mechanism table)
| Step | What happens | Why it matters for hair |
|---|---|---|
| 1 | Dutasteride inhibits Type 1 and Type 2 5-alpha reductase | These enzymes convert testosterone → DHT |
| 2 | DHT levels decrease | Less DHT signaling at susceptible follicles |
| 3 | Follicle miniaturization slows | Can reduce shedding and stabilize density |
| 4 | Over time, some follicles thicken | Possible improvement in hair caliber/density with consistent use |
