What to know

Clinic descriptions are not the same as evidence from controlled trials.
PDRN and polynucleotide treatment schedules differ between clinics.
One clinic reports improved thickness and density in a study of PDRN injections, but study details are limited.
Ask which product you will receive and whether other treatments are included.
Have a dermatologist assess unexplained or symptomatic hair loss before booking.

What the treatment is

PDRN scalp injections place a DNA-derived compound into tissue around hair follicles. Perfect B describes PDRN as a purified nucleotide compound derived from salmon DNA; nucleotides are the building blocks of DNA. That is the basis of the advertising phrase “salmon DNA scalp injection.” It describes the material’s source, not an established result you should expect from treatment.

Polynucleotide treatments sit alongside PDRN in clinic advertising, but you should ask which product is actually being offered. Wonder Medical Spa describes Rejuran hair treatment as polynucleotide-based, while Aura Wellness describes its polynucleotides as DNA fragments from salmon or other natural sources. Our guide to polynucleotides for hair explores the terminology; the descriptions here do not establish that different formulations produce equivalent outcomes.

The proposed benefits are mostly clinic claims, not confirmed treatment effects in the evidence available here. Perfect B claims PDRN reduces follicular inflammation and improves local scalp oxygenation. Aura Wellness makes scalp-repair claims for Rejuran. Before considering either, have a dermatologist assess sudden or patchy loss, scarring, pain, itching, scaling, or loss after illness or a new medication.

What a session involves

A session generally means a scalp assessment followed by injections into thinning areas, according to clinic descriptions. Health & Aesthetics says treatment begins with a consultation in which a doctor assesses your scalp and hair-loss condition. It then describes injecting a polynucleotide-rich solution directly into areas with thinning hair. That description does not establish the exact technique used by every provider.

Appointment length depends on the clinic and treatment area. Health & Aesthetics lists 30 to 45 minutes, while Thérapie Clinic lists 30 minutes for its Plinest Hair treatment. These are service descriptions, not findings from clinical trials. Ask whether your appointment includes the consultation and what preparation, comfort measures, and aftercare the clinic provides; those details are not established here.

Check whether your pdrn hair injection appointment is for PDRN alone or a combined service. Perfect B says its standard medically supervised protocol combines PDRN with exosomes rather than using either alone. A combined appointment is not the same intervention as PDRN alone, so ask the clinic to identify every substance it plans to use and explain the evidence for that combination.

How many sessions clinics describe

There is no single treatment schedule established by the information available here. Perfect B says its patients generally follow eight to twelve injectable PDRN sessions and claims the clinical literature supports that approach. It also reports a study involving 12 sessions. This is a clinic-reported schedule, not enough information to establish how many appointments you personally need.

Schedules for branded polynucleotide treatments differ. Aura Wellness recommends an initial series of 3 to 4 Rejuran sessions spaced 2 to 4 weeks apart, followed by maintenance every 6 to 12 months. Thérapie Clinic describes four Plinest Hair sessions with gaps of 7–14 days. These recommendations concern different services and should not be treated as interchangeable evidence-based instructions.

Ask how the clinic chose its schedule and how it will assess whether treatment is helping. Thérapie Clinic says results are seen in 4–6 weeks and describes gradual improvements in thickness and density, but those are clinic claims. A stated timetable is not a reliable personal forecast, and the evidence provided does not establish a universal maintenance plan.

What the evidence actually shows

The evidence available here is limited: a clinic’s account of a PDRN study and a case report involving exosomes. Perfect B reports that a 2015 study found improved hair thickness and density after 12 sessions of injections into tissue around hair follicles, using PDRN independently of PRP. The study’s design, participant details, comparison treatment, and size of the reported changes are not established by that account.

The supplied case report is not a scalp PDRN trial. It describes a 35-year-old man with refractory beard alopecia areata treated with human umbilical cord-derived exosomes, with or without PDRN. Although the authors reported improvement, a case report cannot establish PDRN’s independent contribution or predict outcomes for thinning scalp hair. Our research guide helps keep these different evidence levels separate.

Mechanism claims also need to stay separate from measured outcomes. Perfect B claims PDRN affects adenosine receptors, inflammation, and capillary formation; Aura Wellness makes cellular-repair claims for Rejuran. The available facts do not provide randomized trials or meta-analyses establishing scalp PDRN effectiveness. Perfect B’s claims of added benefit alongside minoxidil or finasteride likewise do not establish that adding injections will help you.

Side effects and safety uncertainties

Mild redness and swelling are reported by Health & Aesthetics, which says they typically resolve within a day or two. The clinic also says most patients experience minimal discomfort and can resume regular activities immediately. These are clinic descriptions, not adverse-event rates from a controlled study, and they do not establish how every person will respond.

Claims that a treatment is minimally invasive or naturally derived do not settle its safety. Wonder Medical Spa describes Rejuran as safe and professionally administered, while Aura Wellness claims its naturally derived polynucleotides reduce allergic-reaction risk. The information available here does not quantify that risk or provide a complete safety profile. Ask what evidence supports the clinic’s reassurance for the exact product being offered.

Before booking, ask who assesses your suitability, who performs the injections, and whom you should contact about an unexpected reaction. Get the clinic’s aftercare instructions rather than assuming normal activities are suitable for everyone. If you have scalp pain, itching, scaling, scarring, or sudden or patchy hair loss, see a dermatologist before treating the problem as a cosmetic concern.

Cost: what the clinic actually lists

The available pricing is for Thérapie Clinic’s Plinest Hair polynucleotide service, not a general PDRN injection price range. The clinic lists a single treatment session at £245, a four-session package at £195 per session, and an eight-session package at £195 per session. Keep those listed prices attached to that specific service rather than applying them to Rejuran or PDRN elsewhere.

The prices are stated in pounds sterling (£), but the country of treatment is not established in the pricing facts available here. Confirm the country, location, and currency with the clinic before comparing quotes. No supported country-specific PDRN price range is available in this brief, so there is no sound basis for averaging these prices or converting them into another currency.

Ask for a written quote that identifies the product, planned appointments, and what is included. Check whether consultation, follow-up, maintenance, or combined treatments are included or separately charged; the listing here does not establish those details. Our scalp treatment cost guide can help frame your comparison, but your quote should describe the actual service you would receive.

Questions to ask before booking

Start by asking what is causing your hair loss and why this treatment is being proposed for you. Perfect B identifies people with surviving follicles as candidates, while Health & Aesthetics says polynucleotide treatment requires existing hair and will not work on bald patches or total baldness. These are clinic statements, not a diagnosis or a validated way to predict your response.

Ask for the exact product name, whether it is PDRN or another polynucleotide formulation, and whether exosomes or other treatments are included. Then ask which evidence supports that exact service: a clinic claim, a case report, or a controlled study. If you are comparing options, our PDRN versus PRP guide can help you separate the procedures rather than treating all scalp injections as equivalent.

Finish by asking how progress will be documented, when the plan will be reviewed, what happens if there is no meaningful change, and what the full cost includes. Request clear aftercare and contact arrangements. These questions do not turn early evidence into certainty, but they help you understand what you are buying. This guide is informational, not medical advice.

Common questions

Do PDRN scalp injections work for hair loss?

A clinic-reported study offers a signal, not a settled answer. Perfect B reports improved hair thickness and density after 12 PDRN injection sessions in a 2015 study. The study design and size of the changes are not established here, so that report cannot predict your outcome or establish effectiveness across different causes of hair loss.

How many PDRN scalp injection sessions do I need?

There is no universal schedule established here. Perfect B describes eight to twelve PDRN sessions. For Rejuran, Aura Wellness recommends 3 to 4 sessions spaced 2 to 4 weeks apart. Those are clinic recommendations for different services, not a personalized treatment plan. Ask why the proposed schedule fits your assessed condition.

Are PDRN scalp injections painful?

Health & Aesthetics says most patients experience minimal discomfort during polynucleotide scalp treatment. It also reports mild redness or swelling afterward, typically resolving within a day or two. These are clinic descriptions rather than controlled safety data. Ask your provider about comfort measures and the aftercare for your specific procedure.

Is Rejuran scalp treatment the same as PDRN?

The clinic descriptions do not establish that they are identical. Wonder Medical Spa describes Rejuran scalp treatment as polynucleotide-based, and Aura Wellness describes polynucleotides as DNA fragments from salmon or other natural sources. Perfect B describes PDRN as a purified nucleotide compound derived from salmon DNA. Ask for the exact formulation rather than relying on the advertising label.

Can a PDRN scalp serum replace injections?

The available facts do not establish equivalent effects. Perfect B says injections deposit PDRN directly around follicles and claims topical products cannot reach the dermal papilla, a structure it places 3 to 4 millimeters below the skin surface. That is a clinic claim, not a supplied head-to-head trial comparing a serum with injections.
