The Root Cause Hair Restoration Protocol is a physician-designed PRP hair restoration program in Wellington, FL that begins with endocrine-informed evaluation, then delivers customized PRP prepared on the EmCyte PurePRP SupraPhysiologic system in a structured, physician-supervised series with a maintenance plan.
Why most PRP for hair disappoints
Patients arrive at our Wellington office having already tried PRP somewhere else more often than you might expect. They paid for a package, sat through the sessions, and finished the year with hair that looked roughly the same. The conclusion they usually draw is that PRP does not work. The more accurate conclusion is that PRP was delivered to them as a product rather than as medicine, and the three reasons it underperforms are consistent enough that they are worth naming plainly.
1. Weak single-spin preparation
PRP is not a standardized product. What ends up in the syringe depends entirely on the system used to prepare it, and inexpensive single-spin tubes produce a dilute concentrate that still carries a substantial load of red blood cells. Platelets are the point of the treatment, because they carry the growth factors that signal the follicle. A preparation with a modest platelet concentration is delivering a modest signal, and no injection technique compensates for that. Two clinics can both accurately say they offer PRP and be delivering materially different treatments.
2. No evaluation of why the hair is thinning
Hair loss is a symptom, not a diagnosis. Thyroid dysfunction, androgen patterns, iron and vitamin D status, insulin resistance, thyroid medication changes, postpartum shifts, rapid weight loss, and several common prescriptions all suppress hair growth, frequently more than one at a time. A treatment aimed at the scalp while an active internal driver goes unexamined is working against a headwind. That is not a failure of PRP. It is a failure to ask the medical question first.
3. No structured protocol and no maintenance plan
Hair follicles cycle over months, so a treatment plan built around whenever the patient happens to rebook does not match the biology. Nor does a plan that ends the moment the initial package is used up. Follicles that respond to PRP need continued signal, and the patients who hold their gains are the ones on a defined cadence with a maintenance schedule set in advance. Without that structure, the early response fades and it looks, from the outside, like the treatment simply stopped working.
The protocol below exists because each of those three failure modes is fixable. None of them requires a new technology. They require a physician designing the plan, a serious preparation system, and the discipline to follow a schedule.
Medical evaluation, before anything is injected
Every protocol starts with a consultation that looks like an endocrine visit rather than a sales appointment. Dr. Anna Frisch, MD, PhD, is a board-certified endocrinologist with more than 26 years in practice, and the evaluation she designed reflects that training: history first, pattern of loss second, and laboratory assessment where it is clinically indicated.
We take a careful history of when the shedding began, whether it followed a pregnancy, an illness, a surgery, a period of rapid weight loss, or a medication change. We look at the pattern itself, because diffuse thinning, a widening part, temporal recession, and patchy loss point in different directions. Where the history warrants it, screening may include thyroid function including reverse T3, TPO and TG antibodies, androgen markers, ferritin and iron studies, vitamin D, and metabolic markers such as fasting glucose and insulin. When Dr. Frisch determines a panel is warranted, the blood is drawn in-house at the practice and she interprets the results herself, and recent labs from your own physician are welcome. Where iron repletion is indicated it is started and monitored under physician supervision rather than left to over-the-counter guessing, because iron overload carries real risk. For how this plays out in autoimmune thyroid disease, see Hashimoto’s, hair loss and PRP.
We do not promise that a cause will be found. Hair loss is frequently multifactorial, and in a meaningful number of patients the evaluation returns nothing dramatic and the genetic pattern is the dominant story. That is still useful information, because it changes what we expect from treatment and how we talk about the timeline. What we will not do is skip the question. When a correctable contributor is present, addressing it makes every subsequent session more productive, and when it is absent, you proceed knowing rather than guessing.
This step is also where candidacy is decided honestly. Some patients are better served by a dermatology or surgical referral, and where that is the right recommendation, that is what you will hear at the visit.
What we test, and the numbers we actually treat to
Lab work is not part of every visit. When Dr. Frisch determines a panel is warranted by your history, the blood can be drawn in-house and she interprets the results herself as a board-certified endocrinologist. If you already have recent results from your own physician, bring them and your plan can be built on those.
- Thyroid
- TSH, free T3, free T4 and reverse T3
- Autoimmunity
- TPO and TG antibodies
- Iron status
- Ferritin
- Vitamin D
- 25-hydroxy vitamin D
- Micronutrients
- Zinc, selenium, biotin and vitamin B12
Ferritin is where most plans quietly fail
Standard laboratory ranges often report a ferritin of 25 ng per mL as normal. For hair regrowth, Dr. Frisch looks for ferritin consistently above 70 ng per mL. A ferritin that is technically in range and clinically too low is one of the most common reasons topical treatments fail, and no serum, device or injection compensates for it.
Vitamin D is targeted to 50 to 80 ng per mL. Iron repletion is started only when ferritin is below 70 ng per mL, and always under physician supervision, because iron overload carries real risk and is not something to self-treat from a supplement aisle.
Formulation on the EmCyte PurePRP SupraPhysiologic system
Once the evaluation is complete, the second variable we control is what is actually in the syringe. Your blood is drawn in-office and concentrated on the EmCyte PurePRP SupraPhysiologic system, an advanced FDA-cleared concentrating system used at the point of care. It is a deliberate choice and a more expensive one than the alternatives, and it is the reason our preparation is not comparable to a basic single-spin tube.
Supraphysiologic platelet concentration
The system concentrates platelets well above their baseline level in whole blood, which means more of the growth factors that signal the follicle are delivered in each session.
Over 99% red blood cell removal
Red blood cells are contaminant, not therapy. Removing more than 99% of them produces a cleaner preparation and, in most patients, a more comfortable treatment and a calmer recovery.
Customization per treatment area
The formulation is adjusted per patient and per area treated, including neutrophil-poor preparations where delicate work calls for them. Scalp, hairline, and facial applications are not interchangeable.
Closed-system sterility
Processing happens in a fully closed system at the point of care. Your blood is never exposed to open air between the draw and the treatment.
To be precise about the regulatory language, because it matters: the system used to prepare your PRP is FDA-cleared as a concentrating device. PRP is not FDA-approved as a treatment for hair loss, and any practice telling you otherwise is being careless with words. We would rather describe the treatment accurately and let the preparation quality speak for itself.
A structured, physician-supervised treatment series
Treatment runs on a defined cadence rather than an open calendar. Most patients begin with a series of three to four sessions spaced four to six weeks apart, with visible density changes from about three to four months and results assessed at six months, timed to the follicle cycle rather than to convenience. Every session is delivered under physician supervision and follows the protocol Dr. Frisch designed, which means the depth, the pattern of placement, and the volume are consistent from visit to visit instead of improvised.
The intent of the series is to reawaken dormant follicles and encourage thicker growth from follicles that have miniaturized. Growth factors delivered into the scalp signal the follicle environment, and because follicles cycle over months, the response accumulates across sessions rather than appearing after one. A single treatment is a sample, not a plan.
There is no surgery and no meaningful downtime. A session takes under an hour from draw to finish, topical numbing is used, and most patients return to work or the rest of their day immediately afterward. Mild tenderness or pinkness of the scalp for a day is the usual extent of it.
Progress is documented rather than remembered. We photograph under consistent conditions at intervals, because the change is gradual enough that patients living with their own scalp every day are poor judges of it. Most people notice reduced shedding first, with density changes building from roughly 90 to 120 days onward. Individual results vary, and where a patient is not responding as expected, that becomes the conversation rather than another quiet round of the same treatment.
Maintenance, because hair keeps cycling
The initial series is the beginning of the plan, not the whole of it. Follicles continue to cycle, and the underlying tendency toward thinning does not disappear because a series has ended. Maintenance sessions, typically scheduled at intervals set for your response, keep the signal going and are the main reason some patients hold their gains for years while others watch them fade within months.
Where appropriate, maintenance also includes physician-directed support beyond the scalp itself. That may mean nutraceutical support, correcting an iron or vitamin D deficiency the evaluation identified, addressing thyroid management directly with Dr. Frisch, or medical therapies chosen for your situation. These are recommendations made case by case at a medical visit.Your series is planned at consultation.
Because the same regenerative logic applies to skin, some patients continue maintenance across both. Our PRP and PRF services cover facial and under-eye applications, our PRF page covers platelet-rich fibrin specifically, our Wellington PRP page covers the local logistics, and the Collagen Rebuild Protocol is the skin counterpart to this program.
Why an Endocrinologist Designed Our PRP Protocol
Hair loss is rarely just a hair problem. Thyroid function, androgens, insulin resistance, and nutritional status all drive thinning, and a standard med spa is not equipped to consider any of them. Dr. Frisch built the Root Cause Hair Restoration Protocol™ the way an endocrinologist builds any treatment plan: evaluation first, then a customized PRP formulation on the EmCyte PurePRP system, then a structured series with a maintenance plan. It is the difference between buying injections and following medicine.
Dr. Anna Frisch is a board-certified endocrinologist with an MD, a PhD, more than 26 years in practice and internationally cited research. Endocrinology studies how hormones govern hair, skin, weight and energy, which is why the questions asked here differ from those asked where the scalp is treated as a surface.
She designs every regenerative protocol at Palm Beach Cosmetic Medicine and performs every PRP injection herself. The evaluation, the preparation, the formulation, the cadence and the maintenance schedule are hers. Topical PRP with microneedling is provided by our medical aesthetician, working to her protocol.
PRP Hair Restoration + Internal Hair Support
PRP hair restoration at PBCM is designed to support the scalp environment using platelet-rich plasma prepared from the patient's own blood. For patients interested in a more complete hair wellness plan, PBCM may introduce VitellaMD Foundation+™, a physician-developed nutraceutical designed to support hair strength, visible fullness, collagen formation, and nutritional pathways involved in healthy-looking hair. Foundation+™ may be discussed as part of a broader hair wellness routine for men and women seeking internal support alongside their aesthetic treatment plan.

What patients ask about PRP hair restoration
- When do results appear?
- Hair grows slowly, so change is gradual. Most patients notice reduced shedding first, often within the first couple of months, with visible density changes appearing over three to six months as the follicle cycle turns over. Individual results vary, and we photograph at intervals rather than relying on memory.
- Who is a candidate for the Root Cause Hair Restoration Protocol?
- Adults with thinning, widening part lines, reduced density, or increased shedding are the usual candidates, including women in the postpartum and perimenopausal windows and men with early to moderate pattern thinning. Candidacy is confirmed by a physician. Where PRP is not the right tool, or where surgical referral is the honest recommendation, that is what you will hear.
- Why does the endocrine evaluation matter for hair loss?
- Thyroid function, androgens, iron and vitamin D status, insulin resistance, medications, and recent weight loss all influence hair growth. Treating the scalp while one of those drivers is active produces a partial result. We screen for them where clinically indicated first, so the treatment is working with your physiology rather than against it. We cannot promise a cause will always be identified.
- How is your PRP different from a med spa PRP treatment?
- Two differences. First, the evaluation: your protocol is designed by a board-certified endocrinologist and begins with the medical question of why the hair is thinning. Second, the preparation: our PRP is concentrated on the EmCyte PurePRP SupraPhysiologic system, an advanced FDA-cleared concentrating system, with over 99% of red blood cells removed and the formulation adjusted per treatment area.
