Although finasteride is one of only two treatments licensed for the treatment of male pattern hair loss, there are still plenty of ways to treat hair loss without it. Although it’s effective in up to 90% of men at stopping hair loss, it might not be the right fit for you.
We’ll recommend some alternatives that may work instead of finasteride, based on why you might be looking for something different.
Worried about side effects?
As with any medication, finasteride can potentially cause side effects. If you’ve experienced side effects before, or you’re concerned about them, here are some other options.
Minoxidil
Minoxidil is the other licensed treatment for male pattern baldness, clinically proven to stop hair loss in up to 84% of men. It’s non‑hormonal – unlike finasteride, it doesn’t directly lower DHT levels. Instead, it works by improving blood supply to the hair follicles, helping deliver oxygen and nutrients, extending the hair’s growth phase, and promoting growth factors.
When combined with finasteride, it can be effective in up to 94% of men at stopping hair loss, but it also works well on its own. Minoxidil Spray is available over the counter, so no prescription is needed.
Natural alternatives
Many men want to address hair loss but are wary of taking medication. Plant extracts such as saw palmetto, rosemary oil, and pumpkin seed oil show some promise in research, with potential anti‑androgen effects that may reduce DHT levels.
For example, a clinical trial compared finasteride (1mg daily) with saw palmetto (320mg daily). Saw palmetto improved hair growth in 38% of participants, while finasteride improved hair density in 68%. Finasteride was also effective at both the hairline and crown, whereas saw palmetto appeared to work mainly at the crown.
Rosemary oil is another popular option. In one study, rosemary oil performed similarly to minoxidil 2% in increasing hair count. However, minoxidil 5% is the strength with the strongest evidence for effectiveness – something we explain in more detail in this blog.
Some men adopt a “supplement stacking” approach, combining multiple natural treatments to maximise potential benefits. However, there’s currently limited clinical evidence to support how effective this strategy is.
Topical finasteride
Finasteride is typically prescribed as a 1mg tablet for male pattern baldness, but it’s also available in an unlicensed topical spray. Applied directly to the scalp, topical finasteride targets hair follicles while reducing systemic absorption. This may lower the risk of side effects while still reducing scalp DHT levels.
Not seeing results?
Finasteride works well for many men, but results can take time. Before switching treatments, it’s worth checking a few key factors.
1. Hair regrowth takes time
Hair growth is slow. Most men need 3–6 months to notice early signs such as reduced shedding, with clearer results often taking up to 12 months.
2. Your starting point matters
If hair loss is more advanced (around Norwood 4 or higher), finasteride’s main benefit is often stabilisation rather than regrowth. Results vary between individuals.
It’s also important to keep expectations realistic, as follicles that have been inactive for a long time may not fully recover.
If you’re in the early to mid stages of hair loss and have given finasteride a fair try, these alternatives may be worth exploring.
Dutasteride
Dutasteride is a stronger DHT blocker than finasteride. It inhibits both type I and type II 5‑alpha‑reductase enzymes, leading to up to 93% suppression of DHT. However, it’s currently unlicensed for hair loss in Ireland and has a longer half‑life, which may increase the risk of side effects.
In‑clinic treatments
Treatments such as PRP, AMT, red light therapy, and microneedling have become increasingly popular. These typically require clinic visits and can be costly, but may suit those looking for medication‑free options.
At‑home procedures
You don’t always need to visit a clinic for some treatments. With the right equipment, certain options can be done safely at home.
Microneedling: Using a derma roller can create controlled micro‑injuries that may stimulate hair growth and improve minoxidil absorption. Learn more here.
Low‑level light therapy: Devices emitting red light (600–900nm) may improve blood flow and extend the hair growth phase. Be wary of incorrect wavelengths – otherwise, results are unlikely.
We hope this guide helped you explore alternatives to finasteride. While finasteride and minoxidil have the strongest evidence, some off‑licence treatments may still be effective. Always research carefully before investing, as costs can add up.
