Month-by-Month: What PRP Results Actually Look Like
Weeks 1–2: Treatment Settling
Immediately after your first PRP session, your scalp will be mildly sensitive and may show slight redness — similar to mild sunburn. This settles within 24–48 hours. You won't see any visible hair changes yet. The growth factors are beginning their work beneath the surface, activating biological pathways that will produce visible results over the coming months.
Some patients experience a brief "shedding phase" during weeks 2–4. This can be alarming but is actually a positive indicator. It means dormant follicles are being stimulated into a new growth cycle, pushing out old, thin, weakened hairs to make way for thicker, healthier growth. This temporary shedding typically lasts 1–2 weeks.
Weeks 2–4: Reduced Shedding
The first measurable change most patients notice is a significant reduction in daily hair shedding. Fewer hairs in the shower drain, on the pillow, and in your brush. This happens because PRP's anti-apoptotic effect (preventing premature follicle cell death) begins stabilising follicles that were in the process of shedding.
This is your second PRP session. The cumulative effect of multiple treatments is essential — one session alone is insufficient for meaningful results.
Months 2–3: Hair Feels Different
Before you can see changes, you'll feel them. Existing hair begins to feel thicker, stronger, and more substantial between your fingers. The hair shaft calibre is increasing as PRP's growth factors stimulate the dermal papilla cells to produce more robust hair.
Scalp health improves noticeably. Many patients report reduced itching, less oiliness, and an overall healthier scalp environment. This is your third PRP session, completing the initial course.
Months 3–4: Visible New Growth Begins
This is the stage where measurable changes become visible. New growth — initially fine "baby hairs" — begins appearing at the temples, hairline, and crown. Thinning areas start to look denser. The parting line may appear slightly narrower.
These new hairs are in the early anagen (growth) phase and will continue to thicken and lengthen over the following months. Standardised photography at your follow-up appointment will objectively document these changes.
Months 4–6: Continued Improvement
Hair density continues to increase as new follicles enter active growth. Existing hairs reach their improved calibre. The scalp becomes less visible through the hair, particularly at the crown and part line. Many patients begin receiving compliments or comments about their hair looking "healthier" or "thicker" during this period.
Clinical trials confirm statistically significant density increases at the 6-month mark — the average across studies is a 31% increase in hair density.
Months 6–12: Optimal Results
By 6–12 months, PRP's full effect is visible. Hair density, thickness, and coverage are at their peak improvement. Results from this point are maintained through periodic maintenance sessions every 6–12 months.
At The London PRP Clinic, your doctor will assess your progress and recommend a personalised maintenance schedule based on your individual response.
What the Numbers Say: Clinical Outcomes
These are the evidence-based outcomes you can use to set realistic expectations:
Average density increase at 6 months: 31% (2025 meta-analysis, 1,877 patients across 43 RCTs).
Percentage of patients who respond: 87% of hair restoration patients at The London PRP Clinic show visible improvement at their week-16 photo review.
Patient satisfaction rate: 76% across published studies.
Hair pull test improvement: Significant reduction in positive hair pull tests (indicating reduced active shedding).
Hair shaft calibre improvement: Increased thickness of individual hair strands, particularly significant for female patients.
Duration of results: 12–18 months before maintenance is needed.
These numbers represent averages. Some patients achieve more dramatic improvement; others see more modest gains. The patients who typically achieve the best results are those with early-stage hair loss (Norwood I–III, Ludwig I–II), younger patients with more active follicles, patients who complete the full initial course of 3 sessions, patients who combine PRP with pharmaceutical support, and patients at clinics using advanced PRP preparation systems.
When PRP Doesn't Work: The Honest Conversation
No ethical clinic should claim PRP works for everyone. Here's who may not respond:
Very advanced hair loss (Norwood V+): When follicles have been inactive for years and replaced by scar tissue, there is no biological substrate for PRP to stimulate. In these cases, hair transplant surgery is the primary option, with PRP used as a supportive treatment.
Untreated underlying conditions: If your hair loss is driven by untreated thyroid dysfunction, severe iron deficiency, or hormonal imbalance, PRP alone cannot overcome these ongoing metabolic disruptions. This is why our diagnostic blood work is non-negotiable before treatment.
Inferior PRP preparation: Budget clinics using basic centrifugation equipment produce PRP with inconsistent, often suboptimal platelet concentrations. If PRP "didn't work" at a previous clinic, the preparation quality may have been the limiting factor rather than PRP itself.
Insufficient treatment: Patients who undergo only one session or do not complete the recommended course often report disappointment. The cumulative effect of 3+ sessions is essential for meaningful results.
If you have tried PRP elsewhere without success, a consultation at The London PRP Clinic may still be worthwhile. Our doctor-led approach, advanced preparation systems, and comprehensive protocols produce results where other clinics may not have.

Maximising Your PRP Results
Before Treatment
Ensure good hydration. Avoid blood-thinning medications and supplements (aspirin, fish oil, vitamin E) for 48 hours before treatment if medically safe to do so. Eat a nutritious meal beforehand. Arrive with clean, product-free hair.
Between Sessions
Take your Viviscal Professional supplements daily (included with treatment). Consider topical minoxidil as a daily maintenance treatment between PRP sessions. Maintain a balanced diet rich in protein, iron, zinc, and biotin. Manage stress levels — chronic stress undermines hair growth. Protect your scalp from excessive UV exposure.
Long-Term Maintenance
Schedule maintenance PRP sessions every 6–12 months based on your doctor's recommendation. Continue daily supplements and topical treatments. Monitor your hair health through standardised photography at each appointment.
What 87% Success Actually Means
PRP from £545/session. ExoRevive from £445. Marylebone and Canary Wharf locations.
Your Decision
Hair loss is progressive. The follicles you lose while deliberating cannot be recovered without surgery. The patients who achieve the best PRP results are those who start treatment while they still have active, treatable follicles.
A free consultation at The London PRP Clinic gives you a clear diagnosis, an honest prognosis, and a personalised treatment plan — with no obligation to proceed.
