Hair loss affects millions of people worldwide — and one of the top culprits is DHT (Dihydrotestosterone). This potent hormone, a derivative of testosterone, binds to hair follicles and causes them to shrink over time. The result? Thinner strands, receding hairlines, and patchy bald spots.
The good news is that DHT blockers can help fight back. Whether you're dealing with male pattern baldness, female hair thinning, or early signs of hair fall, using the right DHT blocker can slow down shedding and promote regrowth.
In this guide, we break down the 7 best DHT blockers for hair loss you can buy online in 2025 — including topical treatments, oral supplements, and shampoos that actually work.
What Are DHT Blockers?
DHT blockers are products that help prevent DHT from binding to hair follicle receptors. By reducing DHT levels or blocking its effects, these treatments help stop follicle shrinkage and support stronger, healthier hair growth.
There are two types:
-
Internal DHT Blockers: Usually taken as pills or capsules (e.g., Finasteride, Saw Palmetto)
-
Topical DHT Blockers: Applied directly to the scalp via shampoo, serum, or foam
