Every treatment below targets a different biological driver of hair loss, and most patients do best on a combination rather than any single option. This table is a quick reference — follow the link on each treatment name for the full clinical detail, dosing, and expected timeline.

A side-by-side summary of evidence strength, how each treatment is administered, how often, and what it costs — before you read the detail on each individual treatment.
| Treatment | Evidence level | How it's taken | Treatment frequency | Approx. cost |
|---|---|---|---|---|
| Cetirizine | Moderate | 1% topical foam, applied to the scalp | Once daily | ~$1 / day |
| Minoxidil | Strong | Low-dose oral tablet (preferred), or topical solution/foam | Once or twice daily | ~$0.80 / day |
| Dutasteride | Strong | Intradermal scalp injection | Every 3 months | ~$200 / treatment |
| LP-PRP | Strong | Series of scalp injections using the patient's own plasma | Every 3 months | ~$350 / treatment |
Dutasteride and LP-PRP frequencies above refer to ongoing maintenance dosing. LP-PRP typically begins with a more frequent initial course (see the LP-PRP page for the full protocol) before settling into 3-monthly maintenance. Costs are approximate, in AUD, and will vary based on individual assessment and dosing.
