A PRP hair maintenance protocol is not an upsell bolted onto the end of a treatment series. It is the part of the intervention that determines whether any of the preceding sessions were worth performing — and it is the part most practices never build, because they sold a course with a finish line to a condition that does not have one.
Tatiana Sarmiento lists the failure as its own item, separate from technique, separate from diagnosis: "No maintenance plan. The patient thinks one or two treatments is enough and they don't come back. And then they come back two years later saying it didn't work — you didn't go through the whole process that we indicated to you."
Two years later is the detail that matters. That patient did not decide the treatment failed. They drifted, uncorrected, and then reconstructed the drift as a verdict on the treatment. And because androgenetic hair loss is progressive, the scalp they returned with was worse than the one they left with — which made the reconstruction feel true.
This piece is about the architecture that prevents that. It is a practice-management problem wearing clinical clothes, and it has four failure points.
Failure point one: the patient cannot perceive the thing they are paying for
Every retention problem in hair medicine starts here.
A patient buying a lip treatment sees the outcome in the mirror before they leave the building. A patient buying a hair protocol sees nothing for months, by design — the physiology of that delay is worked through in the timeline piece in this cluster. Which means that for the entire duration of the initial series, the patient is paying for an outcome they cannot verify, on the strength of your word.
Word alone does not survive four months. What survives is evidence.
This is why the measurement system is a retention instrument and not just a clinical one. A patient who is shown a baseline image and a current image side by side, with counts from the same fixed target area, is being handed the ability to judge for themselves. A patient who is only told "it's working" is being asked for faith, and faith degrades on a predictable schedule.
Tatiana ties the documentation directly to this problem: "The patient may forget what the hairline looked like… it's very important that you document the first time you see the patient, and then progressively — that's the only way they will actually see the change." Not the only way they will have a change. The only way they will see it.
The operational version: the review of the images is a booked clinical event, not a screen someone shows at the desk on the way out. Put it in the appointment. Give it time. Sit the patient in front of the comparison.
Failure point two: the series was sold as a course, so it ended
If the first conversation frames the treatment as "three or four sessions," the patient will hear a completed course at session four. Everything after that reads as an additional purchase they were not warned about — and patients resent unannounced extensions far more than they resent an expensive plan they agreed to at the start.
The fix is to state the full structure at consultation, before the first session, and never to introduce maintenance later as new information.
The structure Tatiana teaches has three distinct stages, and they do different jobs:
The initial series. "Usually I tell my patient three to four monthly sessions of PRP." Monthly spacing, and her stated rationale for the monthly interval on the facial side applies here too — the aim is to keep re-stimulating rather than to let the signal lapse between visits.
The reassessment. "And then we reassess three months later." A discrete, booked, clinical decision point — not an optional follow-up. It is the visit where the measurements are repeated in full and the plan is either continued, extended or reconsidered.
Ongoing maintenance. "I mention to my patient that this is a treatment you need to repeat every year, because you want to keep giving the growth factor to that follicle. It's like the right nutrition for a follicle that may be weak."
And the series length itself is a judgement, not a package: "Some patients need more treatments — six instead of three. That is an assessment you have to do."
Two things are worth being precise about here. This cadence is a scheduling framework, not a dosing instruction. It describes how often a patient is seen and when decisions are made. It does not specify a volume, a platelet dose or a concentration, and it should not be read as doing so. And it reflects one clinician's practice — published because she teaches it and stands behind it, not because it is a universal standard.
The practical consequence is simple and it is the highest-yield change in this article: book the next appointment before the patient leaves the room, at every visit, including the last one in the series. A maintenance plan that exists only as an intention in the patient's head is not a plan. A patient with a date in their calendar twelve months out is a patient you will see again.
Failure point three: aftercare that defeats the treatment
This is the one clinicians most often miss, because it happens entirely outside the clinic, and Tatiana raises it specifically.
"If it's a female, they use wigs — and they keep using the wigs. The tension will break their hair. So they're never going to see that hair growing back."
The mechanism is traction. Sustained mechanical tension on the hair shaft transmits force to the follicle, and chronic tension produces follicular injury. Early traction alopecia is non-scarring and is reversible if the tension is removed. Left in place long enough, the process can progress to permanent follicular loss — at which point no biologic intervention recovers it, because there is no longer a follicle to stimulate.
The sources of that tension are common, daily and rarely volunteered:
- Wigs and hairpieces secured with tight elastics, combs, clips or adhesive — and frequently worn over exactly the thinning region the patient came to you about.
- Extensions and weaves, particularly bonded, glued or sewn systems that transfer the weight of added hair onto existing shafts, and which are often placed at the temples and hairline where loss is already established.
- Tight braids, cornrows, twists and high ponytails, especially when maintained continuously.
- Chemical processing combined with tension, which compounds shaft fragility with mechanical load.
There is a bitter logic to this that is worth naming out loud to the patient: the concealment is being applied to the area of greatest loss, which is the area under the most treatment, and it is loading the follicles you are trying to rescue. The patient is paying you to stimulate follicles and paying someone else to pull on them.
How to handle it clinically:
Ready to put this into practice?
Explore Empire's hands-on, CME-accredited Functional & Regenerative Medicine courses — live patients, expert faculty, and ongoing mentorship.
Ask directly, at consultation, and examine with the piece removed. Do not rely on the patient to disclose a wig or extensions. Many will not, because the concealment is the point. The question belongs on the intake form and in the conversation, phrased without judgement.
Examine the hairline and temples specifically for the pattern of marginal loss, and record it. If you find traction changes, that finding goes into the record and into the treatment plan, because it changes the prognosis you should be quoting.
Separate "remove permanently" from "reduce load." Telling a patient to abandon concealment during the months when they have the least hair and the least visible result is a request many will not accept, and a refused instruction is worse than a negotiated one. The negotiable version: loosen the attachment, change the attachment points so tension is not applied to the same follicles continuously, avoid adhesives and sewn systems over the treatment field, give the scalp defined periods without the piece, and stop tight styling of the underlying hair.
Document the conversation and the patient's decision. If a patient elects to continue high-tension styling through the protocol, that is their choice to make, and it belongs in the chart alongside a plainly stated prognosis. It protects the patient from a false expectation and the practice from an unwinnable dispute at month twelve.
The same discipline applies to the quieter aftercare variables — concealing fibres and root sprays, which make the photographic series unusable if applied before a documentation visit, and which should be washed out beforehand.
Failure point four: nobody owns the follow-up
The first three failures are clinical. The fourth is administrative, and it is the one that silently destroys the most protocols.
Patients who miss a maintenance visit rarely cancel. They simply do not rebook, and in a practice without a recall system nothing happens. The patient is not thinking about their hair on any particular Tuesday. The system has to think about it for them.
What to build, none of which is sophisticated:
A recall list with a named owner. Every hair patient sits on it with a due date. A named person works it on a defined schedule. If nobody owns it, it does not happen.
Structured chart fields rather than free text. Date of last session, session number within the series, reassessment due date, maintenance due date, last measurement date. Free-text notes cannot be queried, and a recall list you cannot generate is a recall list you do not have.
A lapse policy. Decide in advance what happens when a patient goes past due — at what point they are contacted, how many times, and what is said. Also decide what a returning lapsed patient gets: in most cases a fresh baseline and a fresh measurement set, because the old baseline no longer describes the scalp in front of you.
An outcome-review appointment type that is distinct from a treatment appointment, with time allocated for the comparison and the decision. If the review has no appointment type, it will be squeezed into the last two minutes of a treatment visit and it will not do its job.
A consistent answer to "how long do I have to do this for?" Every member of staff should give the same one. The honest answer, for androgenetic loss, is that it is an ongoing management relationship rather than a fixed course, because the underlying process is progressive and does not stop when treatment stops. Patients accept that answer far better when they hear it at consultation than when they infer it at session four. It is also the answer that frames questions about switching to an adjacent biologic — see exosomes versus PDRN versus PRP — as a change of agent within an ongoing plan rather than as a rescue for a plan that was never completed.
What good looks like
A hair service that retains patients has all of this visible from the outside: a consultation that states the full three-stage structure before any treatment happens, a baseline capture that cannot be skipped, a next appointment booked at every visit, a booked reassessment with the images reviewed in front of the patient, a documented conversation about tension and concealment, an annual maintenance date in the system with a named owner, and a recall process that runs whether or not anyone remembers.
None of that is a marketing programme. It is the clinical protocol, written down to the end instead of stopping at session four.

Frequently Asked Questions
How often should PRP hair patients return for maintenance?
Tatiana Sarmiento's practice is an initial series of three to four monthly sessions, a formal reassessment three months later, and repeat treatment annually thereafter, with the series extended when the assessment supports it. This is a scheduling framework reflecting her clinical practice rather than a universal standard, and it specifies visit timing, not dose.
Do wigs and hair extensions interfere with PRP hair treatment?
They can. Sustained tension from wigs, bonded or sewn extensions and tight styling transmits mechanical load to the follicle and can cause traction alopecia, which is reversible early and can become permanent if the tension continues. Because concealment is usually applied over the area of greatest loss, it frequently loads the exact follicles being treated.
Why do PRP hair patients stop coming back?
Because the result is imperceptible to them for months, the plan was framed as a finite course, no next appointment was booked, and no system recalled them. Each of those is fixable: document objectively so they can see change, state the three-stage structure at consultation, book forward at every visit, and give the recall list a named owner.
Should a lapsed hair patient restart from baseline?
Usually, yes. Androgenetic loss is progressive, so a scalp that has gone untreated for a year or more no longer matches the old baseline images, and comparing against them will misrepresent the starting point. Capture a fresh photographic set and fresh target-area counts, and treat the restart as a new evaluation period.
How should the maintenance conversation be introduced?
At the first consultation, before any treatment, as part of describing what the intervention is. Introducing it after the initial series reads as an unannounced additional cost and damages trust. Framed at the start as ongoing management of a progressive condition, it is accepted as a feature of the treatment rather than a surprise attached to it.
