How Many PRP Sessions for Hair
Most patients need 3-4 initial PRP sessions spaced 4-6 weeks apart, followed by maintenance sessions every 6-12 months. This protocol is supported by clinical evidence and is what we recommend at The London PRP Clinic.
Recommended PRP Protocol
Initial Treatment Phase
Sessions: 3-4 treatments
Spacing: Every 4-6 weeks
Duration: 3-4 months total
Purpose: Build up growth factors, stimulate follicles, establish improvement
Maintenance Phase
Frequency: Every 6-12 months
Ongoing: Indefinitely to maintain results
Purpose: Preserve gains, prevent regression
Why Multiple Sessions?
Single sessions don't work well because:
Hair follicles need repeated stimulation
Growth factors need to accumulate
Hair growth cycle takes months
One treatment can't sustain long-term results
Studies Show:
Patients receiving 3+ sessions have significantly better outcomes than those receiving 1-2
Maintenance treatments preserve results long-term
Without maintenance, results gradually fade over 12-18 months
What Happens at Each Session
Session 1:
Initial treatment
Begin stimulating dormant follicles
May notice reduced shedding within 2-4 weeks
Session 2 (4-6 weeks later):
Reinforce initial treatment
Growth factors accumulate
Hair may start feeling stronger
Session 3 (4-6 weeks later):
Consolidate results
Visible improvement usually begins
Hair density increasing
Session 4 (optional, 4-6 weeks later):
For more advanced hair loss
Further enhancement
Maintenance (every 6-12 months):
Preserve results
Prevent regression
Top up growth factors
Factors Affecting Treatment Frequency
You May Need More Sessions If:
Hair loss is more advanced
Starting later in hair loss journey
Aggressive progression
Underlying health factors
You May Need Fewer Sessions If:
Very early hair loss
Primarily maintenance/prevention
Excellent response to initial treatment

What If I Can Only Afford Fewer Sessions?
Something is better than nothing, but results will be limited. If budget is tight:
Start with 2 sessions minimum

Consider combining with minoxidil/finasteride
