Referring to Affirmed
Affirmed Medical is a physician-owned practice in Midtown Manhattan that focuses on a single procedure: PRP for Hair Growth.
Our practice is evidence-based, and we publish our full research literature review on our website.
In the last few years, the amount and quality of data for PRP has grown, and its use has increased significantly in the world of dermatology and hair loss.1–6
PRP use has also increased in non-licensed, cosmetic settings that violate New York State regulation and endanger patient safety. New York State maintains that PRP is a medical procedure that requires licensed providers.7
We strive to offer:
- the highest quality PRP
- on the most consistent schedule
- at the most transparent price point
This page is designed to share:
- The current state of evidence for PRP for hair growth along with the sources
- Information on how to refer your patients to a physician at Affirmed
We'd also like to extend an invitation for you to meet with our Medical Director, Paolo Dib, MD.
Dr. Dib can share his perspective on our protocol, literature, and practices, or answer any questions you may have.
ABOUT THE PRACTICE
Physician-Owned and Led
Affirmed Medical is owned and managed by physicians. Decisions about how care is delivered, which protocols we follow, how long visits take, and how often a patient is seen are made by physicians.
Every patient you refer to Affirmed is seen by a physician before confirming they are a candidate for treatment. We offer consultations virtually and in-person.
One procedure
We exclusively offer PRP for hair growth. This focus allows us to perfect the process and to strive for gold-standard quality.
Why membership
Adherence is the biggest challenge when it comes to PRP: patients sometimes get it done, are happy with results, then are disappointed when they go back to their pre-treatment baseline.8–9
And a main barrier to adherence is cost. Derm offices charge well above $1,000-$2,000 per treatment. We took that number, broke it down, and rebuilt it while keeping an evidence-based, gold-standard protocol, and eliminating luxury premiums that are often folded in to the higher procedure prices.
Another barrier to adherence is the logistics that come with any procedure that's simultaneously painful and delayed in effect or even just preventative in effect. Patients might understandably choose not to do the orchestrating it takes to overcome those barriers.
That's why we work exclusively with a membership model. It makes it clear to the patient that if they're medically a candidate and choose to move forward with PRP, they should expect to continue treatment if they see results and would like to maintain them.8–9
Another benefit of that model is that cost is spread out to reduce the burden of intermittent or unpredictable high bills.
We don't lock patients into anything long-term. Memberships have no minimum terms to serve out, and no cancellation fees. A patient who stops owes only the visits they've already received.
This design accounts for non-responders (~10%) as well as for inevitable changes in financial situations.
THE PROTOCOL
Evidence indicates the most important factor for PRP for hair growth results is the platelet dose that reaches the target area. Specifically, the clinically effective target number of platelets is about 5 billion.10–15
Assuming a patient on the lowest end of the platelet reference range, to reach that many platelets from the blood, we'd need to inject up to 33 mL.10–13,16–17
Since the scalp can only comfortably take about 5 mL, the platelets must be concentrated into an injectable amount of PRP.10–15
This means the target concentration is about 1 billion platelets per mL.10–15
Platelet concentration in the blood varies from person-to-person and cannot practically be measured before every treatment, so we make the safe assumption that every patient is at the lowest end of the reference range or at about 150 (million plts/mL of blood).10–13,16–17
7 mL of blood × 150 million plts/mL = 1 billion platelets
Additionally, PRP preparation typically recovers about 80% of the platelets in the blood (i.e. 20% are lost), and we prepare ours with FDA-cleared EmCyte devices. We operate with a safe margin and assume 65% of the platelets are preserved.10–13,18
In order to make sure we get enough platelets from the blood draw, we draw 54 mL of blood.10–13
54 mL × 150 million platelets/mL × 65% = 5.27 billion platelets
We then produce the concentrated PRP using a double spin method. Put together, every patient gets at least the target dose of 5 billion platelets in 5 mL of PRP.10–13,19

Cadence
Ramp-Up
While we generally recommend patients receive PRP for Hair Growth about once every three months, for new patients, we often recommend and offer a “ramp-up” consisting of a treatment each month for the first three months to accelerate the results.24–27
Steady-State
At steady-state, we typically recommend patients receive PRP every three to four months. This cadence may be updated based on the patient's goals and response. Results are maintained for as long as the patient continues receiving PRP.8–9
What we tell patients to expect
Visible improvement typically starts 3 months in. Without the ramp-up, results come more slowly, starting around 6 months, and full results take around 12 months. Without maintenance, effects start to wear off at 12 to 16 months. We do not promise regrowth, and long-dormant areas (>1-2 years) are unlikely to respond to PRP.24,28–33
YOUR PATIENT'S FIRST VISIT
A consult is a 30 min office visit with a physician, during which we go over history, prior and current alopecia treatments, then we conduct a scalp exam as well as digital trichoscopy to measure hair density.
Even though most patients who see us have already been evaluated by a provider before or are already on pharmacotherapy for alopecia, there's a small chance we may opt to rule out underlying etiologies that might be contributing to alopecia.34
That assessment may be done prior to or in parallel with PRP at the recommendation of the physician. If upon assessment a patient is deemed not to be a candidate medically, they aren't charged, because your referral link bypasses the $70 consultation fee.
WHO IS A CANDIDATE
- Pattern hair loss in men and women, where follicles are miniaturising rather than gone.1–2,4,14,16,19,24,31–33,35–40
- Diffuse androgenetic thinning in women, including patients who do not want or cannot take systemic medication.26,28,31–33,35–36,39,41–43
- Patients on testosterone whose androgenic thinning follows the same pattern as any other androgenetic loss.17,31–33
- Post-hair-transplant patients, for the graft and for the native hair around it — there is a whole page on that at PRP After a Hair Transplant.10,31–33,44–50
- Patients who were quoted a per-session price they cannot sustain, and so stopped. PRP requires consistent maintenance, which is a cost problem as much as a clinical one.8–9
- Many other indications now have evidence to support them, including some scarring alopecias, alopecia areata (autoimmune), and chronic telogen effluvium.5,34,51
- If you are unsure, we are happy to evaluate the patient and determine if they are a candidate.
Who is not a candidate: a patient who wants one-time treatment. Scalp areas with >1-2 years of no hair growth whatsoever (not even miniaturized follicles).8–9,31–33
Before you refer
In patients with known or suspected thyroid disease, iron deficiency, or vitamin or mineral deficiencies, labs would help inform their overall, likely multifactorial picture.34,52
A patient with a known derm diagnosis affecting the scalp that is not currently well controlled, or with a new rash that is undiagnosed, would also benefit from management prior to referral.34
WHAT PRP COSTS
We operate with a membership model, which means we don't offer per-session pricing. Receiving only a few PRP sessions is a waste of time and money.8–9
Our pricing breaks down to $600/treatment. This is not an amount the patient pays, it is spread out because of the membership.
Paying your doctor, medical assistant, and technician
Your single-use PRP Kit and medical supplies like gloves and syringes
Facility, practice margin, and insurance
The membership plans multiply the $600/treatment cost by the number of treatments in a year, then spread the total evenly into monthly payments. For example, if a patient opts for a Q3 months maintenance plan over a year:
4 treatments × $600/treatment12 months = $200/month
There are no extra fees or costs. Everything is captured in that membership fee.
We accept FSA and HSA cards, and the patient's benefits plan decides whether the payment itself is authorized. Hair loss is a medical condition, and we document the diagnosis and its medical management so a patient can show their plan if it asks.
MAKING REFERRALS
A patient who schedules a consult using your link bypasses the $70 consultation fee. You can refer a patient in two ways:
- Using the refer a patient form. We'll reach out at the phone number you provide within one business day.
- Give the patient our QR code or link. To do that, request a referral link and we'll email you the QR code, the link, and a one-page handout to print or send to your patients.

Not yet. PRP is not FDA approved for the treatment of hair loss, though PRP preparation systems have earned FDA clearance for other medical applications. A growing body of research supports PRP as an effective treatment for hair loss with no known long-term risks. For those reasons, PRP has been increasingly used off-label in medical settings for hair restoration and preservation
Even though some people space maintenance out to a wide range of every 3 to every 12 months, we currently offer membership for the 3-month and 4-month frequency as we believe it sets you up for success and prevents losing results from prior treatments. We continue to monitor high-quality studies comparing the different frequencies and update our practice accordingly9–10,24
Three things can keep PRP from working. It acts only on follicles that are still alive, so it might not work on skin that has been bare for years. Its effects wear off after treatment stops, so results depend on keeping up maintenance. And most commercial PRP systems do not reach the platelet concentration generally considered effective, which is why Affirmed uses a protocol that ensures every preparation is made to meet the evidence-backed platelet concentration target8–13,19,27,31–33,53
Platelet-rich plasma is not a standardized product, meaning it can look very different in one clinic than another clinic18,53
Experts agree that PRP should have a target concentration of at least a 1 billion platelets per mL to be effective. However, when you look at what various clinics use, that target is often missed.10–13
A review of 33 commercial preparation systems found platelet concentrations ranging from 0.52× to 9.7× of baseline platelets. Only ten of them reached the target concentration considered effective. Some of them even had plasma less concentrated than the blood it came from.18,53
We use the EmCyte PurePRP double-spin system, which reaches the target platelet concentration, with 78 to 81% platelet recovery. The entire process is designed and overseen by a board-certified physician19,55
There are 3 reasons that could explain it
- The kits we use to make PRP are the highest quality on the market and probably the most expensive at about $190
- Our procedures are exclusively done by licensed medical professionals
- We don't use PRF (Platelet Rich Fibrin). PRF bypasses the need for a kit altogether, but it isn't nearly as well-studied as PRP7,56–57
We continuously monitor research studies to keep our practice up to date
