PRP and PRF for hair: what to know before you start

Hair restoration starts with identifying the cause of thinning

PRP and PRF are regenerative treatments prepared from a patient's own blood and injected into selected areas of the scalp. They are commonly discussed for certain patterns of hair thinning, yet treatment should start with an assessment rather than assuming every type of hair loss will respond the same way.

PRP and PRF are prepared differently

Both treatments use components derived from the patient's blood. Preparation methods differ, including how the sample is processed and the resulting platelet or fibrin composition. Practices may use one method based on their protocol and the treatment plan.

Who may be considered

Candidate selection depends on the pattern, duration, and cause of hair thinning. A provider may recommend medical evaluation when hair loss is sudden, patchy, associated with scalp symptoms, or potentially connected to an underlying condition.

Regenerative injections are generally discussed as one option within a broader hair-restoration plan.

The timeline is measured in months

Hair growth cycles are slow. Patients should expect progress to be evaluated over months rather than days. A treatment series and maintenance schedule may be recommended depending on the practice protocol and response.

What the appointment involves

Blood is drawn and processed, then the prepared product is injected across selected scalp areas. Temporary tenderness, pinpoint bleeding, or swelling can occur. The practice should provide aftercare instructions for washing, exercise, and scalp products.

• Ask whether your pattern of thinning is appropriate for regenerative treatment.

• Expect progress photos to be more useful than daily mirror checks.

• Discuss the recommended series before committing to treatment.

• Seek medical evaluation when the pattern of hair loss is unusual or rapidly changing.

Westside takeaway

PRP or PRF can be worth discussing when a provider has identified a pattern of thinning that may respond to regenerative treatment. The most useful consultation covers candidacy, treatment schedule, cost, and the point at which progress should be reassessed.
