HAIR LOSS MEDICATION
Every treatment plan starts right here.
Before PRP. Before a transplant. Before anything. Medication is the foundation, and skipping it is the most common mistake people make when they start looking at hair restoration options.
Minoxidil and finasteride are the two medications with the strongest clinical evidence for treating androgenetic hair loss. Prescribed and monitored by Dr Jai, they slow DHT-driven progression, stimulate follicle activity, and in many cases produce real, visible improvement without any further intervention
Stop the loss before you think about
replacing it.
Medication changes that equation. By targeting DHT, the hormone responsible for shrinking follicles and shortening the growth cycle, finasteride slows or stops the progression at a physiological level. Minoxidil works on the anatomical level, improving blood flow to the scalp and stimulating follicle activity. Used together, they address the condition from both directions.
Dr Jai's approach is consistent: medication is always the first conversation. For many patients, it produces results meaningful enough that surgery is never needed. For those who do proceed to transplant, medication before the procedure reduces the area that needs to be treated and continuing it afterwards protects the rest of the hair from the progression that hasn't stopped.
The hormone behind
most hair loss.
The key distinction: follicles that have been miniaturised by DHT are often still alive and recoverable. Once they are gone, the follicle completely inactive, and they cannot be stimulated back into growth. This is why the timing of treatment matters. The earlier medication begins, the more there is to protect.
Hair at the back and sides of the scalp is not affected by DHT, which is why this hair is used in transplant procedures. It retains its growth characteristics regardless of DHT levels. Hair on the crown and frontal scalp does not have that resistance and is where progression is felt first.
Two mechanisms. One shared goal.
- Applied topically to the scalp: drops or foam, once or twice daily depending on formulation
- Works at the anatomical level: directly improving the scalp environment for follicle growth
- Effective for both male and female hair loss: one of the few treatments clinically validated for women
- Converts thin, miniaturised vellus hair into thicker terminal hair: patients often notice increased hair density before visible growth
- Must be continued: stopping medication typically leads to reversal of the benefit within months
Form: Topical solution or foam
Frequency: Once or twice daily. Dr Jai advises on appropriate formulation and dose
Onset: Initial shedding is common in the first 4–6 weeks
Results visible: Typically 3–6 months of consistent use before meaningful density improvement
- Oral tablet: once daily, requires a prescription from a qualified medical practitioner
- Works at the physiological level: targets the hormonal cause of hair loss directly
- Primarily indicated for male androgenetic alopecia: not typically used in women of childbearing potential due to teratogenic risk
- Most effective when started early: while there are still viable follicles to protect
- Must be continued for sustained effect: hair loss typically resumes within 6–12 months of stopping
- Carries documented side effects: requires medical assessment, monitoring, and ongoing follow-up
Form: Oral tablet. Prescription required
Monitoring: Regular follow-up with Dr Jai for side effects assessed and dose adjusted if needed
Onset: 3–6 months before visible benefit; full effect at 12 months of consistent use
Results visible: Slowing of loss first; density improvement in suitable patients over 6–12 months
What Medication Achieves
Ordering online is not the
same as treatment.
Medical history affects suitability
- Minoxidil is a blood pressure medication. For patients already on antihypertensives or with cardiovascular conditions, the combination can cause hypotension.
- Finasteride interacts with hormone levels. Neither should be started without a proper medical assessment.
Side effects need monitoring
Finasteride carries documented psychiatric side effects. In 2024, the European Medicines Agency launched a safety review of its link to suicidal ideation, particularly in younger men. The UK's MHRA updated labelling requirements. These are real risks that require ongoing doctor oversight, not a subscription service with an automated check-in.
Dose and formulation need adjustment
What works at month three may not be the right approach at month nine. A doctor who is tracking your progress can adjust dosage, change formulations, add PRP where appropriate, and recognise when the situation has changed and the plan needs to change with it.
It is part of a plan, not a standalone product
Medication is most effective when it forms part of a considered treatment plan, not purchased in isolation. Understanding where you are in your hair loss journey, what the medication can and cannot achieve, and how it connects to what comes next requires a clinician, not a checkout page.
Progress needs to be tracked
Without baseline photography and regular review, it is impossible to know whether medication is working. Patients who self-manage often either stop too early (before results are visible) or continue indefinitely without knowing whether the treatment is actually doing anything.

Frequently Asked Questions
Minoxidil is available over the counter in Australia, though a prescription is required for some formulations. Finasteride is a prescription-only medication; you cannot legally obtain it without a doctor's assessment and authorisation. Both should be taken under medical supervision, regardless of how they are obtained.
They work differently and complement each other. Minoxidil improves blood flow to the scalp and directly stimulates follicle activity; it works anatomically. Finasteride blocks the conversion of testosterone to DHT, removing the hormonal driver of hair loss; it works physiologically. Together, they address hair loss from both directions and are more effective in combination than either alone.
Initial shedding in the first 4–8 weeks is common, and normal follicles are cycling. Visible slowing of loss typically occurs within 3 months. Meaningful density improvement takes 6–12 months of consistent use. Clinical trials show superior results at 24 weeks or longer. Stopping early significantly undersells the outcome
Minoxidil is available without prescription; finasteride technically requires one, though online platforms have made it easier to access without proper oversight. The issue is not whether you can; it is whether you should. Finasteride in particular carries documented psychiatric risks, interacts with other conditions, and should not be started without a medical history review and ongoing monitoring.
For both minoxidil and finasteride, the benefits are not permanent; they depend on continued use. Stopping minoxidil typically causes the hair gained to shed within 3–6 months. Stopping finasteride removes the DHT block and progression resumes, usually within 6–12 months. If you need to stop for any reason, discuss the transition with Dr Jai rather than stopping abruptly.
Most patients tolerate long-term finasteride without significant issues, but it carries documented risks that require monitoring. The most important are sexual side effects (affecting a minority of users) and psychiatric effects, including depression and, in rare cases, suicidal ideation. In 2024, the European Medicines Agency launched a formal safety review. Regular check-ins with Dr Jai are part of how these risks are managed.
Topical minoxidil is used for female hair loss and is one of the most clinically validated treatments available for women. Finasteride is generally not prescribed to women of childbearing potential due to teratogenic risk, it can affect foetal development if the patient is or becomes pregnant. The appropriate medications for women are assessed individually at consultation.
Yes, before and after. Before surgery, medication reduces the area that needs to be treated. After surgery, it protects the existing hair around the transplanted grafts. Without it, the surrounding hair continues to thin due to DHT, eventually leaving the permanently transplanted hair increasingly isolated. Dr Jai includes medication review as part of every transplant consultation.
Yes, this is a documented outcome. The transplanted hair is permanent and unaffected by DHT, but the existing hair around it is not. If medication is stopped and progression continues, the natural hair thins progressively until only the transplanted islands remain, creating an unnatural halo effect. This is one reason medication is considered a permanent part of the treatment plan, not a temporary measure.
Yes, and this combination is more effective than either alone. Medication addresses the hormonal cause and maintains the scalp environment; PRP directly stimulates follicle activity and improves hair calibre. Dr Jai designs protocols that combine both, where the clinical picture calls for it.
