Wondering whether to start oral minoxidil or finasteride first? We compare their roles and help you decide the right order for your hair loss treatment.
Quick answer
Start with finasteride if you want to block the hormone DHT that causes male-pattern hair loss. Add oral minoxidil later if you need a growth stimulant. For most men, using both together — as in a combined plan — gives the best results because they tackle different root causes.
How finasteride and oral minoxidil work differently
Finasteride is a prescription medication that blocks the conversion of testosterone into DHT, the hormone that shrinks hair follicles in male-pattern baldness. By lowering DHT levels, it helps stop further hair loss and can maintain existing hair. Oral minoxidil, on the other hand, is a vasodilator that increases blood flow to the scalp, stimulating hair follicles to grow thicker, longer hair. It does not affect hormones, so it works well alongside a DHT blocker.
Because they address separate parts of the hair loss process, many treatment plans combine both. For example, the Core Plan from Sons UK pairs finasteride with minoxidil in a single regimen, giving you the two clinically proven treatments for male-pattern hair loss in one step.
Which should you take first?
If you are new to hair loss treatment, start with finasteride. It targets the underlying hormonal cause, and you can assess how your hair responds before adding a growth stimulant. For men who have already been on finasteride for several months and want more regrowth, adding oral minoxidil can boost results.
That said, many men choose a combined plan from the beginning to save time and simplify their routine. The Advanced Plan and Ultimate Plan from Sons UK include both finasteride and minoxidil plus a Hair Growth Complex, giving you a complete solution without having to decide the order yourself.
Key trade-offs
- Start with finasteride alone: You address the root cause (DHT) first, which may be enough to stop hair loss. It's a simpler, lower-cost starting point. Best if you want to minimize medications and see if a single treatment works.
- Start with oral minoxidil alone: You stimulate growth without affecting hormones. This can work for some men but won't stop the underlying DHT-driven loss. Less effective as a standalone for male-pattern baldness; consider combining with finasteride.
- Start both together: You tackle both causes simultaneously, which often yields faster and more noticeable results. Plans like the Core Plan or Advanced Plan make this easy. Most effective route for men committed to a long-term hair loss strategy.

- Men who prefer a combined, all-in-one regimen — start with a plan that includes both finasteride and minoxidil.
Not for
- Men who want only a growth stimulant without addressing hormonal causes — oral minoxidil alone won't stop DHT-related loss.
- Men who are not ready for a daily medication routine — both finasteride and minoxidil require consistent use.
