Minoxidil
Applied to the scalp for suitable pattern hair loss. Some people notice early shedding; visible benefit commonly takes around 2–4 months, and continued use is normally required to maintain it.
Read the minoxidil guide →Assessment of hair-loss pattern, duration, medical causes and suitability for licensed or established treatment.

The aim is to identify the pattern and likely cause first, then choose a realistic treatment and review plan. Treatment can slow further loss and may improve density, but no medicine works for everyone or restores follicles that are no longer active.

Read the minoxidil guide →Reduces DHT and is licensed for suitable men with early male-pattern hair loss. Stabilisation usually requires 3–6 months; benefit is maintained only while treatment continues. Suitability and possible sexual or mood effects must be reviewed.
Read the finasteride guide →Dutasteride also lowers DHT but is authorised for prostate treatment, not hair loss. Any off-label consideration requires an individual medical decision, careful risk discussion and is never an automatic prescription.
Read the dutasteride guide →It may slow progression and can improve hair count or density when follicles remain active. Long-standing complete baldness is much less likely to regrow.
No. Hair grows in cycles. Baseline photos and consistent use are important because meaningful comparison usually takes several months.
No. Response depends on the diagnosis, duration, pattern, adherence and individual biology. Sudden or patchy loss may need examination or blood tests instead.
The first appointment establishes the diagnosis, checks safety and agrees how progress will be measured. Stable treatment can then move to a simpler renewal route.
Review onset, family history, scalp photographs, medicines, health conditions and whether examination or blood testing is needed.
If suitable, the doctor explains the medicine, correct use, side effects, realistic expectations and when to make contact.
Review consistent photographs, shedding, density, adherence and side effects. Treatment may be continued, changed or stopped.
When the diagnosis, medicine and dose are established and unchanged, suitable renewals may use the focused repeat-prescription service. New symptoms, side effects or dose changes need another doctor consultation.

No. Treatment can slow progression and may improve density while follicles remain active, but it cannot guarantee regrowth and is less likely to restore long-standing complete hair loss.
Visible benefit commonly needs two to four months of consistent use. Some users notice temporary increased shedding early in treatment, and benefit usually requires continued use.
Finasteride commonly needs three to six months before stabilisation or visible benefit can be assessed. Continued treatment is generally required to maintain the effect.
No. Dutasteride is authorised for benign prostate enlargement rather than hair loss. Any off-label discussion requires an individual medical assessment and does not guarantee prescribing.
The doctor reviews the pattern, timing, family history, scalp photographs, medicines, health conditions and previous treatment, then decides whether treatment, examination or blood testing is appropriate.
Not always. Once treatment and dose are established, unchanged and well tolerated, suitable renewals may use the focused repeat-prescription service. Changes, side effects or new symptoms require another doctor consultation.
A useful comparison often occurs after three to six months using consistent photographs. The doctor may recommend a different interval according to the treatment, diagnosis and safety considerations.
Sudden, patchy, inflamed or scarring hair loss, scalp disease, systemic symptoms or suspected nutritional or hormonal causes may require examination, blood tests or specialist referral.
