Hair PRP, minoxidil and finasteride are among the approaches used to manage male androgenetic alopecia. These treatments do not act in the same way: PRP stimulates cells surrounding the hair follicle, while minoxidil and finasteride act through specific pharmacological mechanisms.
The treatment choice depends on the stage of hair loss, the patient's age, medical history, treatment tolerance and objectives. In certain cases, several approaches may be combined within a comprehensive strategy.
PRP, minoxidil and finasteride: what are the differences?
Criterion | Hair PRP for men | Minoxidil | Finasteride |
|---|---|---|---|
Main objective | Stimulate still-active follicles and improve hair quality | Promote the hair growth phase and slow hair loss | Reduce the action of DHT involved in follicular miniaturisation |
Type of treatment | Medical treatment with platelet-rich plasma injections | Topical treatment applied directly to the scalp | Oral medication |
Mechanism of action | Growth factors contained in the patient's platelets | Action on the follicular cycle and prolongation of the anagen phase | Inhibition of 5-alpha-reductase, reducing testosterone conversion to DHT |
Use | In-clinic sessions following a personalised protocol | Regular application needed to maintain the effect | Regular use required under medical supervision |
Timeframe for assessing results | Several months, according to the natural hair cycle | Gradual results after several months of use | Results generally assessed after several months of treatment |
Best candidates | Men with follicles still present and mild to moderate loss | Men with progressive alopecia requiring continuous treatment | Men selected after medical assessment of the benefit–risk balance |
Action on a completely bald area | Limited if follicles are no longer functional | Limited without active follicles | Cannot recreate lost follicles |
Possible side effects | Temporary redness, tenderness or discomfort after injection | Possible scalp irritation, dryness or itching | Possible sexual or psychological adverse effects in some patients |
Treatment requirements | Maintenance sessions needed according to progress | Continuous application needed to maintain benefits | Continuous treatment needed to retain its effect |
After stopping | The natural progression of alopecia gradually resumes | Benefits gradually decrease after stopping | Alopecia-related hair loss may gradually resume |
PRP, minoxidil or finasteride: which treatment should you choose for male hair loss?
These three treatments should not be considered equivalent or competing. They address different mechanisms of male hair loss.
PRP has the advantage of using the patient's own blood components and acting directly to stimulate still-active follicles. However, effectiveness depends strongly on the stage of alopecia: it is less suitable when hair loss is too advanced.
Minoxidil has documented effectiveness in male androgenetic alopecia, but requires regular, prolonged use. Stopping treatment gradually leads to loss of the benefit achieved.
Finasteride acts on the hormonal component of alopecia by reducing DHT production. This treatment may be effective in certain patients, but requires a prescription and full medical information about possible adverse effects. Swissmedic notably mentions precautions concerning certain sexual side effects and mood disorders reported in some users.
A medical consultation selects the most suitable strategy: PRP alone, medication, a combination of approaches or referral for a hair transplant when follicular stimulation is no longer sufficient.
