Male hair loss: what works, what doesn't, and when to start
A clinician-reviewed guide to male pattern baldness — the evidence behind treatments, timelines, and the myths to ignore.
By 50, around half of men have noticeable hair loss. Male pattern baldness is hormonal and genetic: hair follicles sensitive to DHT (a by-product of the hormone testosterone) gradually shrink until they stop producing visible hair. Two honest facts frame everything else: treatments work better at keeping hair than regrowing it, and starting earlier beats starting later.
What hair loss treatments have real evidence?
Topical treatment applied to the scalp stimulates follicles and can slow loss and thicken existing hair. It’s available over the counter in the UK, takes 3–6 months to show effects, and must be continued to maintain them.
Tablet treatment that lowers DHT is prescription-only and is the more effective option for most men — the majority who take it stop losing further hair, and many see some regrowth. It requires a clinician conversation about a small risk of side effects.
Combining both is more effective than either alone, which is why many UK clinics offer combination plans. Compare tablet vs spray.
What doesn’t have good evidence?
Most “hair growth” shampoos, laser combs at consumer prices, and the majority of supplements have weak or no evidence for pattern hair loss. Supplements only genuinely help when hair loss is driven by a deficiency — iron, for example — which a clinician can check.
What timeline should you expect?
Whatever you start, judge it at six months, not six weeks. Photographs in consistent lighting are more honest than the mirror. Initial shedding in the first weeks can occur as the hair cycle resets — unsettling but often normal.
If a product promises regrowth in weeks, it’s marketing, not medicine.
When should you start hair loss treatment?
If you’re noticing recession or thinning and it bothers you, the best time to ask is now: every follicle preserved is one you don’t need to regrow.
A discreet online assessment can establish what’s realistic for your pattern and stage — see hair loss plans.
Who should skip this?
Skip online hair programmes if the loss is sudden, patchy, or from the scalp with scale and pain — that can be alopecia areata or infection, not pattern baldness. Skip if you are a woman using a male-pattern page. Skip guaranteed regrowth adverts.
NHS, high-street pharmacy, or online clinic?
GPs check thyroid, iron and medicines when the pattern is atypical. Minoxidil 5% foam or solution is a nameable pharmacy option. Daily oral tablets for male pattern hair loss are prescription-only and we will not name them in adverts. GP suits sudden, patchy, or female hair loss, or other symptoms. Skip that route if classic male pattern you already recognise.
How should you choose a route?
| Option | Best for | Skip if |
|---|---|---|
| GP | Sudden, patchy, or female hair loss, or other symptoms | Classic male pattern you already recognise |
| Minoxidil | Crown thinning, you can apply twice daily | You want a tablet class a pharmacist cannot start |
| Online clinic | Male pattern, you want a full private plan after assessment | Patchy loss that needs a diagnosis |
What should you expect if you go online?
Results take months. Shedding at the start can happen with minoxidil. Stopping usually means losing what you gained. Photos help you stay honest about progress. GP suits sudden, patchy, or female hair loss, or other symptoms. Skip that route if classic male pattern you already recognise.

Frequently asked questions
Can hair loss be reversed?
Treatment can regrow hair in many men — especially at the crown — but works best at preserving existing hair. Follicles that have been miniaturised for years may not fully recover. Starting before advanced thinning gives the best chance.
At what age should you start hair loss treatment?
Whenever pattern thinning bothers you — often mid-20s to 40s. Earlier treatment preserves more follicles. There is no benefit to waiting until hair is visibly sparse.
Is hair loss treatment permanent?
Results last while you continue treatment. Stopping usually allows pattern baldness to resume over months as DHT effects return. Think of it as ongoing maintenance, like skincare.
Do hair loss treatments work on the hairline?
Topicals often help crown and mid-scalp most. Oral DHT-blocking tablets can slow recession broadly but regrowing a deeply receded hairline is harder than preserving density — another reason to start early.
Will a £200 shampoo regrow hair?
Unlikely. Licensed minoxidil has evidence; miracle shampoos usually do not. Be sceptical of before/after ads.
Can I use someone else’s oral hair tablet?
No. It is a prescription-only pathway with sexual and mood side-effect discussions a clinician should have with you.
