Do you need maintenance PRP after an initial hair treatment course?
Some people with pattern hair loss are offered maintenance platelet-rich plasma (PRP), but there is no single proven lifelong schedule for everyone. The right next step is a review of diagnosis, response, tolerability and cost, not automatic renewal because a package has ended. If the first course has not produced a convincing benefit, ask what evidence supports more treatment before paying for it.
Ask The London PRP Clinic by The Wellness about a hair-loss review. Bring the dates of your previous sessions and comparable photographs. A personalised plan should explain whether further PRP is reasonable, what it is intended to achieve and when the decision will be revisited.
What the evidence supports, and what it does not
PRP has been studied mainly as a treatment for androgenetic alopecia, often called male or female pattern hair loss. A 2024 systematic review of male androgenetic alopecia included eight randomised trials and one cohort study, with 291 participants. Several studies found improvements in hair density or count, but the authors emphasised low-quality evidence, moderate risk of bias and substantial differences between studies. That supports a careful discussion of possible benefit, not a guarantee of regrowth. Donnelly and colleagues, Journal of Cosmetic Dermatology.
The same limitations matter when selling maintenance. Evidence that PRP can improve a study outcome over several months is not proof that everyone needs injections indefinitely, or that a particular interval is best for years. Ask whether the recommendation is based on your observed response, a published regimen or the clinic's usual protocol. Those are different kinds of support.
Why clinics may discuss repeat sessions
The American Academy of Dermatology describes PRP as involving repeat visits, often three monthly sessions followed by sessions every three to six months. This is general patient information, not a promise that this schedule is right for you or that The London PRP Clinic uses it in every case. AAD, diagnosis and treatment of hair loss.
One small randomised study compared two initial regimens in 40 people over six months. It found a greater hair-count improvement in the group receiving three monthly sessions followed by a booster three months later than in the group receiving two sessions every three months. The study compared specific early regimens. It did not establish a universal lifelong maintenance calendar. Hausauer and Jones, randomised trial.
This distinction is important for a high-value decision: a short-term study can inform the conversation without settling your long-term spending plan.
Review the response before agreeing to more
Start with the goal agreed before treatment. Was the aim greater coverage in a defined area, reduced progression, or another measurable change? Ask the clinician to compare your baseline and current assessment rather than relying on a flattering photograph taken in different light.
A useful review asks:
- Is the original diagnosis still the best explanation for the loss?
- Do comparable images or measurements show a meaningful change?
- Have other treatments changed during the same period?
- Was the course completed as planned, and were there problems?
- What would make another session worth the time, discomfort and cost?
- What finding would lead us to stop, pause or change approach?
If several treatments started together, photographs cannot tell you precisely which one caused any improvement. That does not make the improvement unimportant; it means the conclusion should be honest.
A maintenance plan should have a decision point
Ask for the proposed interval and number of sessions in writing, with the reason for choosing them and a review date. The plan should explain the expected benefit and uncertainty, relevant risks, what is included in the fee and how progress will be assessed. Do not assume a discounted course is the best value if it commits you to treatment before the response is understood.
If your concern is progression despite treatment, say so directly. Ask whether another assessment or referral is more useful than another injection. AAD explains that hair-loss diagnosis may involve examination, a pull test, blood tests or a scalp biopsy depending on the suspected cause. Not every person needs every investigation. AAD.
When it is reasonable to reconsider the plan
A change in symptoms or the pattern of loss deserves review rather than being automatically labelled “time for a booster”. AAD notes that infections and painful inflammation can require treatments directed at the cause. PRP should not be treated as a substitute for finding out why the scalp has become painful or inflamed. AAD hair-loss treatment guide.
Tell your clinician about new symptoms, medicines and any changes in your health before another procedure. Do not stop prescribed treatment or change a home-care plan just to create a cleaner test of PRP. Discuss changes with the clinician who manages that treatment.
Paying for judgement, not an open-ended course
Premium hair care should mean a clear diagnosis, realistic expectations, careful documentation and an opportunity to reconsider. It should not depend on the fear that missing one appointment will undo everything. The evidence above does not support an exact “expiry date” for your result.
Contact The London PRP Clinic to discuss a review before committing to further sessions. Ask the team to confirm the clinician, scope, current fee and availability. If you are comparing a course, read our hair PRP package guide alongside a current personalised quote; an older online price is not a checkout confirmation.
Does everyone need PRP every three months?
No universal interval is established here. General schedules described by professional patient guidance are a starting point for discussion, not an individual prescription.
Can I stop after the first course?
Discuss the response and alternatives with your clinician. A decision to continue should explain the expected value of further treatment rather than assume renewal.
Does a lack of improvement prove PRP never works?
No. It means your own diagnosis, response and plan need review. Research averages do not guarantee an individual benefit.
Can maintenance guarantee that I will keep all my hair?
No. A guarantee of permanent density or complete prevention of future hair loss would go beyond the evidence discussed here.
