Dealing with thinning hair? DHT — dihydrotestosterone — shrinks hair follicles in people with genetic hair loss. Blocking DHT can slow that process. Here are natural options that people use, the real evidence behind them, and simple tips for trying them safely.
Saw palmetto: One of the most common choices. Small clinical trials show saw palmetto can reduce scalp DHT and improve hair counts for some men. Typical doses are 160–320 mg daily of standardized extract. Expect at least 3–6 months to see changes.
Pumpkin seed oil: A 2014 randomized trial reported better hair growth with pumpkin seed oil versus placebo after 24 weeks. Try 1 tablespoon (about 10 mL) daily of cold-pressed oil or a standardized capsule dose used in studies.
Stinging nettle: Often paired with saw palmetto. Nettle root may block enzymes that convert testosterone to DHT. You can find it as capsules or tincture; follow product dosing on the label.
Green tea (EGCG): The catechin EGCG can interfere with DHT activity in lab studies and may support scalp health. Drink 2–3 cups of green tea daily or use an EGCG supplement if needed.
Rosemary oil: Topical rosemary oil is a practical option. A 6-month study showed rosemary oil was as effective as minoxidil 2% in improving hair growth, with less itching. Mix a few drops into a carrier oil or buy a rosemary scalp serum.
Pygeum and beta-sitosterol: Both contain plant compounds that can influence androgen pathways. They're used more often for prostate health but can help DHT-related issues. Products typically combine them with saw palmetto.
Dietary zinc and lycopene: Zinc supports healthy hormone balance and enzymes that process androgens. Lycopene from cooked tomatoes or supplements may help too. Don’t exceed recommended zinc doses—high intake causes problems.
Start one change at a time so you can tell what helps. Use standardized extracts when possible — that means consistent active ingredient. Be patient: hair cycles move slowly; give any approach at least 4–6 months. For topical oils, massage the scalp to improve circulation and product contact.
Watch for side effects: saw palmetto can cause stomach upset and interact with blood thinners; high zinc can cause nausea and copper deficiency. If you’re on hormones, blood thinners, or have prostate issues, check with your doctor first.
Combining natural blockers with proven treatments (like topical minoxidil) often gives better results than relying on one method. Track progress with photos every month so you can judge changes realistically.
If hair loss is sudden, patchy, or accompanied by other symptoms, see a healthcare pro — that could signal a different condition that needs testing or prescription treatments.
Lifestyle matters: quality sleep, regular exercise, and less sugar help hormones and inflammation, which can reduce DHT activity. Avoid tight hairstyles and harsh chemical treatments. Natural blockers usually slow hair loss rather than fully regrow thick hair, so set realistic goals and keep tracking progress for better results. Stay consistent.
