How Many PRP Sessions for Hair

By Dr Jones2 min read

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.

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

Ideally, commit to the full protocol. PRP is an investment—doing it properly maximises return.
