Overview
Platelet-Rich Plasma (PRP) therapy is a non-surgical hair restoration treatment that uses your body’s own growth factors to stimulate hair follicle activity, slow hair thinning, and promote thicker, healthier hair growth. PRP has emerged as one of the most promising non-surgical options for patients experiencing early to moderate hair loss who want to take action before hair loss progresses to the point of requiring surgical transplantation.
At The Ferguson Clinic in Honolulu, PRP hair restoration is administered under the supervision of Dr. John C. Ferguson, MD, FACS — a quintuple board-certified cosmetic and facial plastic surgeon whose training in head and neck surgery includes a deep understanding of scalp biology, blood supply, and the tissue environment that supports hair growth. This is not a cosmetic treatment administered in a vacuum — it is a medically supervised procedure performed by a team that understands the science of hair loss and the full spectrum of treatment options.
Am I a Good Candidate?
You may be a good candidate for PRP hair restoration if you are in the early to moderate stages of hair thinning or loss; have miniaturizing hair follicles (follicles that produce progressively finer, shorter hairs); want to complement a hair transplant to enhance graft survival and growth; are looking for a non-surgical treatment option; or want to maintain and strengthen existing hair.
PRP is most effective when hair follicles are still present but weakened — producing thinner, finer hairs rather than no hair at all. For areas of complete baldness where follicles have been absent for years, PRP is unlikely to regrow hair, and surgical transplantation may be more appropriate.
Patients with certain blood disorders, active scalp infections, or who are on blood-thinning medications may not be candidates for PRP. Dr. Ferguson evaluates each patient individually during the consultation.
The Procedure — What to Expect
PRP hair restoration is performed in-office at The Ferguson Clinic in Honolulu and takes approximately 60 to 90 minutes.
Step 1 — Blood Draw: A small amount of blood (typically 30 to 60 milliliters) is drawn from your arm, similar to a routine blood test.
Step 2 — Centrifugation: The blood sample is processed in a centrifuge, which separates the blood components and concentrates the platelets. The resulting platelet-rich plasma contains a high concentration of growth factors — including platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and transforming growth factor (TGF) — that play key roles in tissue repair and regeneration.
Step 3 — Injection: The concentrated PRP is injected directly into the scalp at the level of the hair follicles using a fine needle. Injections are distributed across the treatment area in a precise pattern. A topical numbing agent or local anesthetic block is used to minimize discomfort.
The entire process uses your own blood, eliminating the risk of allergic reactions or rejection. There is no synthetic material or foreign substance involved.
Recovery and Results
PRP has essentially no downtime. Most patients return to their normal activities immediately after treatment.
Day 1: Mild soreness or tenderness at the injection sites. Slight redness may be present. Patients can wash their hair the following day.
Weeks 1–4: The growth factors begin to work at the cellular level, stimulating follicular activity. There are no visible changes yet during this initial phase.
Months 2–3: Early signs of improvement may become noticeable, including reduced hair shedding and a sense that existing hair feels thicker or stronger.
Months 4–6: More noticeable improvement in hair thickness, density, and coverage. New hair growth from previously dormant follicles may become visible.
Months 6–12: Continued improvement with ongoing treatment. Results are cumulative and build over time.
A typical initial treatment protocol involves three to four sessions spaced four to six weeks apart, followed by maintenance treatments every four to six months. Dr. Ferguson customizes the treatment schedule based on each patient’s response and degree of hair loss.
Frequently Asked Questions
Does PRP really work for hair loss?
PRP has a growing body of clinical evidence supporting its effectiveness for androgenetic alopecia (pattern hair loss) in both men and women. Multiple peer-reviewed studies have demonstrated improvements in hair count, hair thickness, and the growth phase of the hair cycle. While individual results vary, the majority of patients experience measurable improvement. Dr. Ferguson at The Ferguson Clinic in Honolulu monitors your response and adjusts the treatment plan accordingly.
How many PRP sessions will I need?
Most patients begin with three to four sessions spaced four to six weeks apart, followed by maintenance treatments every four to six months. Dr. Ferguson tailors the protocol to each patient’s response and severity of hair loss.
Does PRP hurt?
A topical numbing agent or nerve block is applied before the injections. Most patients describe the discomfort as mild — a series of small pricks with brief pressure. The treatment is well-tolerated.
Can PRP be combined with a hair transplant?
Yes. PRP is an excellent complement to hair transplant surgery. When administered before, during, or after transplantation, PRP can improve graft survival, accelerate healing, and enhance the growth of transplanted follicles. Dr. Ferguson frequently recommends this combination for hair restoration patients in Honolulu.
Is PRP safe?
PRP uses your own blood, so there is virtually no risk of allergic reaction or rejection. The most common side effects are mild soreness and temporary redness at the injection sites. When performed by a qualified physician like Dr. Ferguson, PRP is a very safe procedure.
When will I see results from PRP?
Most patients begin to notice improvement in hair thickness and reduced shedding within three to six months. Full results develop over six to twelve months with continued treatment. Patience and commitment to the treatment protocol are important.
Why Choose Dr. Ferguson for PRP Hair Restoration
PRP for hair restoration is widely available, but the quality and effectiveness of treatment vary based on the preparation protocol, injection technique, and the treating physician’s understanding of scalp biology. Dr. Ferguson’s training as a head and neck surgeon includes a detailed understanding of scalp anatomy, blood supply, and tissue biology — knowledge that informs how and where PRP is delivered for maximum effect. His approach is clinical and evidence-based, monitored with objective assessments of hair density and quality, not marketing promises. For patients in Hawaii exploring non-surgical hair restoration, Dr. Ferguson offers the combination of scientific rigor and clinical expertise that produces the best possible outcomes.
