Is PRP Effective for Hair Loss?
Yes — PRP (Platelet-Rich Plasma) therapy is clinically effective for hair loss, with the strongest evidence supporting its use in androgenetic alopecia (pattern hair loss) and alopecia areata. It works best as a proactive, maintenance-phase treatment or as an adjunct to hair transplant surgery. It is not a standalone replacement for transplantation in cases of significant hair loss. For early stages of hair loss, PRP helps improve thinning and density of hairs.
PRP has moved well beyond the “experimental” category. It’s now one of the most prescribed non-surgical hair loss interventions in Perth and across Australia — and with good reason. But it’s also one of the most misunderstood. Patients arrive expecting miraculous regrowth after one session; others dismiss it entirely as a wellness fad. The truth is more nuanced — and more useful.
Here’s the honest clinical picture.
What Is PRP Hair Treatment?
Platelet-Rich Plasma therapy uses your own blood to stimulate hair follicle activity. The process involves:
- Blood draw — a small sample (typically 20–60ml) is taken from your arm
- Centrifugation — the blood is spun in a centrifuge to separate platelets from red blood cells, concentrating growth factors
- Injection — the platelet-rich plasma is injected directly into the scalp at follicle depth across the target area
The growth factors in platelets — including PDGF, VEGF, EGF, and FGF — stimulate dormant or miniaturised follicles, increase blood supply to the scalp, and prolong the active (anagen) phase of the hair growth cycle.
There is no foreign substance involved. No synthetic chemicals. It’s your biology, concentrated and redirected. With PRP procedures, hair thinning can be addressed effectively, especially at early stages of hair loss.
What Does the Research Say?
Multiple peer-reviewed studies support PRP’s efficacy for androgenetic alopecia. A 2023 systematic review published in the Journal of Cosmetic Dermatology found statistically significant improvements in hair density, thickness, and patient satisfaction scores across most study populations treated with PRP over 3–6 sessions.
Importantly, results are strongest in patients who:
- Are in the early to moderate stages of hair loss
- Still have active follicles (miniaturised, not dead)
- Commit to a full treatment protocol of at least 3 sessions
- Use PRP in combination with other treatments (minoxidil, finasteride, or post-transplant)
PRP cannot regrow hair from follicles that have been completely dormant for years. Think of it as fertiliser — it helps what’s alive grow stronger, but it can’t plant new seeds.
Who Is PRP Really For?
PRP is best suited for:
- Men and women with androgenetic (pattern) hair loss in early to mid stages (Norwood II–IV, Ludwig I–II)
- Post-transplant patients looking to protect native hair and accelerate graft growth
- Diffuse hair thinning patients not yet candidates for surgical intervention
- Alopecia areata patients (emerging strong evidence base)
PRP is less effective for:
- Advanced hair loss where large areas of scalp show no follicular activity
- Scarring alopecias (e.g., lichen planopilaris) where follicles are permanently damaged
- Patients on blood thinners or with platelet disorders
How Many PRP Sessions Do You Need?
The standard PRP protocol recommended by most Perth hair specialists in 2026 is:
- Initial phase: 3 sessions spaced 4–6 weeks apart
- Maintenance phase: 1–2 sessions per year ongoing
Results are typically visible from 3–6 months after commencing treatment, as hair growth cycles are slow. Patients who stop after a single session and report “no results” have not given the treatment a fair trial.
Some patients with more aggressive hair loss or those combining PRP with transplant surgery may benefit from more frequent early sessions. Your specialist will tailor the protocol to your scalp assessment.
How Much Does PRP Cost in Perth?
PRP pricing in Perth varies by clinic type, the centrifuge system used, and whether sessions are sold individually or as packages.
| Session Type | Average Cost (Perth, 2026) |
| Single PRP session | $400 – $600 |
| Package of 3 sessions | $1,100 – $1,600 |
| Annual maintenance session | $400 – $600 |
| PRP combined with hair transplant | Often bundled — ask your clinic |
Clinics using medical-grade centrifuge systems (which produce higher platelet concentration) may charge at the upper end of this range — and the quality difference is clinically meaningful. Ask your clinic about their platelet concentration protocol and system.
PRP vs Other Non-Surgical Hair Loss Treatments
| Treatment | How It Works | Best For | Typical Cost (Perth) |
| PRP | Growth factor injection | Early–moderate hair loss | $400–$600/session |
| Minoxidil (topical) | Vasodilator; extends anagen phase | Pattern hair loss | $30–$80/month |
| Finasteride (oral) | DHT blocker | Male pattern hair loss | $30–$60/month |
| Exosome therapy | Stem cell-derived growth factors | Advanced non-surgical cases | $400–$600/session |
| Low-level laser therapy | Photobiomodulation | Adjunct use | $50–$200/session |
What to Expect During and After a PRP Session
During: The blood draw is quick. Scalp injections cause mild discomfort — similar to a standard scalp sensitivity. Most patients rate pain at 2 or 3/10. Numbing cream or local anaesthetic is often used. Sessions take 45–60 minutes.
After: Mild redness and scalp sensitivity for 24–48 hours is normal. Avoid washing your hair for 24 hours post-treatment. Resume normal activity the same day. Avoid blood thinners for 48 hours pre-session.
What you won’t see: Instant results. PRP is a biological process, not a topical fix. Patience and commitment to the protocol are part of the treatment.
Frequently Asked Questions
Is PRP effective for hair loss?
Yes. Clinical evidence supports PRP for androgenetic alopecia and alopecia areata, particularly in early to moderate stages. It’s most effective as part of a multi-modal treatment plan.
How many PRP sessions do I need for hair loss?
Most Perth hair clinics recommend an initial course of 3 sessions spaced 4–6 weeks apart, followed by 1–2 maintenance sessions per year. Results emerge gradually over 3–6 months.
How much does PRP cost in Perth?
Individual PRP sessions in Perth typically cost between $400 and $600. A package of three sessions ranges from $1,100 to $1,600 depending on the clinic and centrifuge system used.
Does PRP hurt?
Discomfort is typically mild. Most patients experience a 2 or 3/10 sensation from scalp injections. Topical numbing cream is usually applied beforehand to improve comfort.
How long do PRP hair treatment results last?
Results from an initial PRP course can last 12–18 months. Ongoing annual maintenance sessions are recommended to sustain outcomes, particularly for patients with progressive hair loss.
The Honest Assessment
PRP is not a miracle cure. It’s a clinically supported, well-tolerated treatment that buys time, preserves existing hair, improves hair density and enhances the outcomes of surgical procedures. For the right patient, it’s genuinely excellent. For someone with advanced hair loss hoping to avoid a transplant, it’s likely to disappoint.
A good Perth hair doctor or Trichologist will tell you upfront whether you’re a strong candidate — and won’t oversell it.
