PRP for Hair Loss: What It Can and Cannot Do
Platelet-rich plasma (PRP) uses growth factors from your own blood to improve hair caliber and support follicles at risk.
The goal is thicker, stronger hair in areas that are thinning, not a new hairline on a slick scalp.

How PRP Works
Your blood is drawn and spun to concentrate platelets. PRP is injected with tiny needles into areas of miniaturizing hair.
Platelets release signaling proteins that can extend the growth phase and improve hair shaft diameter over time.
Who Is a Good Candidate
- Early to moderate thinning from pattern hair loss
- Postpartum or stress-related shedding after evaluation
- Support around transplants or to maintain gains from medical therapy
PRP is less helpful for areas that are completely bald for years. Expectations matter. We review photos and medical history at consult. Read my surgeon profile if you are new here.
Treatment Plan
- Series: 3 sessions spaced 4–6 weeks apart
- Maintenance: Every 4–6 months depending on response
- Comfort: Topical anesthetic and small injections; sessions are brief
- Photos: Baseline, 3 months, 6 months, then yearly for honest comparisons
What to Expect and When
- 1–2 months: Shedding often stabilizes
- 3–6 months: Hair feels thicker; coverage improves in thinning zones
- 6–12 months: Best read of results; maintenance keeps gains
PRP thickens existing hairs. It does not replace hairs that are completely gone.
What PRP Pairs Well With
- Topicals: Minoxidil foam or solution
- Oral options: As appropriate after medical review
- Low-level light caps/combs: Adjunct for some patients
- Microneedling: Protocols vary; we use it selectively
Safety and Downtime
- Autologous: It is your own blood product
- Common effects: Scalp tenderness, mild swelling or headache for a day
- Avoid before/after: Anti-inflammatory pain meds 24–48 hours, sauna and strenuous workouts for 24 hours, harsh hair products the first day
- Not a fit if: Active scalp infection, certain platelet disorders, significant anticoagulation, or you are pregnant
Quick Guide
| Situation | PRP Likely Outcome | Plan |
|---|---|---|
| Early thinning with miniaturized hairs | Thicker shafts and better density | Series + maintenance; add minoxidil |
| Receded hairline with bare skin | Limited change | Discuss surgical options or different goals |
| Recent postpartum shedding | Stabilization then gradual thickening | Medical review first; gentle plan |
FAQ
Does it hurt
Most patients describe brief stings. We use numbing and small needles to keep it tolerable.
Will I shed more at first
Some notice a short shed window as hairs cycle. It settles and density improves over time.
How long do results last
Pattern loss is chronic. Maintenance sessions help preserve gains.
Next step: Bring recent photos and any hair medications you use. We will confirm candidacy and map a realistic PRP plan.
