How to use

  1. 01

    Step 1

    Take once daily

    Take one tablet at the same time each day, with or without food. Oral finasteride is available as 1 mg tablets for hair loss. If you are taking topical finasteride, apply it to the scalp as directed.

  2. 02

    Step 2

    Consistency is key

    Hair growth treatments take time. Take your medication every day without skipping. Set a daily reminder if needed.

  3. 03

    Step 3

    If you miss a dose

    Take it as soon as you remember. If it is almost time for your next dose, skip the missed one. Do not take two doses at once.

Treatment pathway

Your finasteride pathway

  1. Months 1-3

    • One 1 mg tablet daily

      Same time every day, with or without food. DHT suppression starts within days; visible change takes months.

  2. At 6 months — do your photos show less shedding, stabilisation or regrowth?

    Yes

    Continue daily

    Full effect is judged at 12 months; benefits persist only while treatment continues.

    No

    Doctor review

    Your doctor may add topical minoxidil or reassess the diagnosis.

    Months 1-3
  3. Optimising results

    Keep it simple

    • Finasteride alone

      Effective for most men at the crown and mid-scalp.

    Best results

    • Add topical minoxidil

      The combination outperforms either treatment alone in clinical studies.

Report mood changes or sexual side effects — your doctor can adjust the plan.

Combining a DHT blocker with topical minoxidil outperforms either alone in men; your doctor will advise the right combination.

Side effects

01

Less common side effects

Some patients may experience decreased libido, erectile dysfunction, or reduced ejaculate volume. These are uncommon and usually resolve when treatment is stopped. If you experience any of these, discuss with your doctor.

02

Scalp irritation (topical)

If using topical finasteride, you may experience mild scalp irritation, dryness, or itching. This usually improves with continued use.

06 / 10 · Do not use if

  • Women — finasteride 1 mg is for men only; women who are or may become pregnant must not handle crushed or broken tablets
  • Under 18 years old
  • Allergy to finasteride or any tablet ingredient
  • Severe liver disease
  • Already taking finasteride or dutasteride for prostate enlargement

Tell your doctor before any prostate (PSA) blood test — finasteride roughly halves PSA values and the lab must correct for it.

07 / 10 · When to contact your doctor

Contact your doctor if

  • Persistent side effects that concern you (sexual, mood changes, breast tenderness or enlargement)
  • Any scalp reaction that does not improve (topical form)
  • No visible improvement after 12 months of consistent use

08 / 10

Storage

Store at room temperature below 25°C. Keep in the original packaging to protect from light and moisture. Do not use after the expiry date on the carton.

09 / 10

What to expect

Finasteride works by blocking the conversion of testosterone to DHT, the hormone that causes hair loss in men. It stops further hair loss in most patients and can promote regrowth. Results take time — consistent daily use for 6-12 months is needed before judging effectiveness. Treatment is long-term; if you stop taking it, hair loss will return within 6-12 months.
