PRP Hair Restoration in Scarsdale, NY

In androgenetic hair loss, follicles do not vanish overnight — they miniaturise, producing progressively finer, shorter hairs over years. PRP delivers concentrated growth factors from your own blood into the scalp to support those weakening follicles while they are still viable. That is the essential point about timing: PRP can support a struggling follicle, but it cannot resurrect one that is gone. Treating early, when thinning is visible but the area is not yet bare, is where results are best.

PRP is a treatment for early-to-moderate thinning where living follicles remain. If an area is completely bare, the honest answer is that grafting — not PRP — is what will put hair there, and we will tell you so.

• Early androgenetic thinning in men, particularly the crown and mid-scalp
• Female pattern thinning with widening of the part
• Increased shedding after pregnancy, illness, rapid weight loss or significant stress
• Thinning that started alongside a hormonal change, including perimenopause
• Patients who want to support a hair transplant result
• People who would rather not take a daily medication, or cannot tolerate one

PRP for hair has a real evidence base, and also real variability between studies. Both things are true and you should know both before you commit to a course.

Does it work?. Most randomised trials and the systematic reviews pooling them show PRP increasing hair density and shaft thickness compared with placebo, with statistically significant differences at three and six months. It is one of the better-supported non-pharmaceutical options for androgenetic alopecia.

Why results vary. Because the treatment is not standardised. Platelet concentration, spin protocol, activation and injection technique all differ between clinics and between studies, and reviews consistently identify that variability as the main reason outcomes are inconsistent. PRP is not one treatment; it is a family of them.

How it is prepared here. Comparative work favours double-spin preparation over single-spin for hair, and activated over non-activated PRP. We prepare accordingly. It is a small technical decision with a real bearing on whether you see a result.

Timing and expectations. Expect a series of sessions spaced over several months, then maintenance. Improvement is measured in reduced shedding and increased density over months, not in visible regrowth within weeks. Anyone promising the latter is selling.

What it will not do. PRP does not restore hair to a scalp with no viable follicles, and it does not stop the underlying genetic process. It supports what you still have. For an area that is already bare, a transplant is the honest recommendation.

Find the cause first. Not all hair loss is genetic. Thyroid dysfunction, low ferritin, vitamin D deficiency, hormonal shifts and post-partum telogen effluvium are all common, all treatable, and all missed if nobody runs the bloodwork. We run it before assuming the answer.

Your own blood, nothing synthetic. Prepared from a small draw at your visit. No drug, no implant, no daily medication if you would rather not take one.

For men and women. Female pattern hair loss is common, under-treated, and often dismissed. It is treated here with the same seriousness as male pattern loss.

Works alongside other treatments. PRP combines with minoxidil, oral therapies and nutritional correction. It is also used to support hair transplant results rather than competing with them.

We look for the cause, not just the symptom. Thyroid disease, iron deficiency, hormonal shifts and post-partum changes all cause hair loss and all respond to treating the underlying problem. We test rather than assume it is genetic.

Preparation quality matters, and ours is deliberate. Trial evidence shows double-spin preparations outperforming single-spin for hair. That is a technical decision most patients never get told about.

Physician-performed. Your scalp is assessed and injected by a physician, in a medical clinic, not by a technician in a salon setting.

Roughly an hour in our Scarsdale office, with no downtime that stops you going back to work.

1. Scalp assessment and bloodwork. We examine the pattern and density of loss and run labs to rule out thyroid, iron and hormonal causes before assuming the loss is genetic.
2. Blood draw. A small volume drawn in office, exactly as for any lab test.
3. Double-spin preparation. The sample is processed to concentrate the platelet fraction, using the preparation approach the comparative literature supports for hair.
4. Scalp injection. A series of small injections across the thinning areas. Topical numbing is used and most patients describe it as very tolerable.
5. Series and maintenance. Sessions are spaced over several months, with review to assess density before planning maintenance. You will be told the expected schedule before you start.

For androgenetic hair thinning, the pooled evidence is positive. A meta-analysis of nine trials in 257 patients found a standardised mean change in hair density of 1.21 — a large effect by conventional thresholds. Most trials show increased density and shaft thickness versus placebo, with differences most consistent at three and six months.

Because PRP is not a standardised product. Preparation method changes the result dramatically: in the same meta-analysis, double-spin preparation produced an effect of 2.66 against 0.52 for single-spin, and the double-spin trials agreed with each other far more closely. Ask any clinic whether they use a double-spin protocol — it is a better question than price.

No. PRP supports follicles that are still alive but miniaturising. It cannot resurrect a follicle that is gone. For an area that is already bare, grafting is the honest recommendation, and we will say so rather than sell a course that will not work.

A series over several months followed by maintenance. Published protocols cluster around three sessions at monthly intervals, with some running to six. No single regimen has been established as optimal, so you should be told your expected schedule before you begin.

Yes. Female pattern thinning is common and frequently dismissed, and it is treated here with the same seriousness as male pattern loss. In women the underlying causes — iron, thyroid, and hormonal change — are often more relevant, which is why bloodwork comes first.

Because not all hair loss is genetic. Low ferritin, thyroid dysfunction, vitamin D deficiency, hormonal shifts and rapid weight loss are all common, all treatable, and all missed if nobody looks. Injecting a scalp while ignoring a thyroid problem wastes the treatment. If a clinic offers hair PRP without bloodwork, you are being sold a procedure rather than treated for a condition.

Yes to both. PRP is commonly used alongside minoxidil and oral therapies rather than instead of them. As a transplant adjunct, a review of three controlled studies in 217 patients reported graft survival of 82.2% with PRP against 74.0% without, and earlier onset of growth.
