What PRP Therapy Actually Is
PRP (Platelet-Rich Plasma) therapy involves drawing a small amount of your own blood, spinning it in a centrifuge to concentrate the platelets, and injecting that concentrated solution into your scalp. The theory is straightforward: platelets release growth factors that can stimulate dormant hair follicles, extend the growth phase of existing hair, and improve blood supply to the scalp.
It's been used in orthopedics and wound healing for decades. Its application for hair loss is newer but backed by a growing body of clinical evidence — with some important caveats.
What the Research Says
Multiple peer-reviewed studies and meta-analyses have found that PRP therapy can increase hair density and thickness in patients with androgenetic alopecia (pattern hair loss). A 2019 systematic review in Dermatologic Surgery analyzed eleven randomized controlled trials and found statistically significant improvements in hair count and density compared to placebo.
However, the evidence comes with qualifiers. Results vary significantly based on the preparation method, platelet concentration, injection depth, and treatment frequency. There is no universal standardized protocol, which means outcomes can differ between clinics using different systems.
The honest take: PRP is not a miracle cure for advanced hair loss. It works best for early-stage thinning (Norwood 2–3), as a complement to a hair transplant to improve graft survival, or as maintenance therapy to slow ongoing loss. It will not regrow hair in areas that are completely bald.
PRP Cost: Colombia vs the US
| Treatment | Colombia | United States | Savings |
|---|---|---|---|
| Single PRP session | $300–$500 | $1,000–$1,500 | 60–70% |
| 3-session package | $800–$1,200 | $2,500–$4,000 | 65–70% |
| PRP + hair transplant combo | $2,500–$5,500 | $10,000–$18,000 | 65–75% |
| Annual maintenance (2 sessions) | $500–$800 | $1,800–$2,500 | 65–70% |
The Treatment Process
A typical PRP session takes about 45 minutes to an hour. The blood draw is minimal — usually 20 to 60 milliliters, similar to a routine blood test. After centrifugation (which takes about 15 minutes), the concentrated plasma is injected across the thinning areas of your scalp using fine needles.
Most protocols recommend three initial sessions spaced four to six weeks apart, followed by maintenance sessions every six to twelve months. Some clinics apply topical anesthetic before injections, though many patients find the discomfort manageable without it.
There's no downtime. You can wash your hair the next day and resume all normal activities immediately. Mild scalp tenderness for 24 to 48 hours is the most common side effect.
Who Benefits Most from PRP?
Strong candidates
Patients with early-stage thinning who want to slow progression. Those who have recently had a hair transplant and want to maximize graft survival. Men and women who aren't ready for surgery but want an active treatment beyond topical medications. Patients who respond poorly to or can't tolerate finasteride.
Limited benefit expected
Patients with Norwood 5 or higher baldness where follicles are long gone. Those expecting PRP alone to create dramatic density improvement. Anyone looking for a one-time fix — PRP requires ongoing maintenance.
PRP as a Transplant Companion
Where PRP really shines is as part of a comprehensive hair restoration strategy. Many Colombian clinics now include a PRP session immediately after transplant surgery and recommend follow-up sessions at three and six months. Early research suggests this can improve graft survival rates and accelerate the timeline for visible new growth.
If you're traveling to Colombia for a hair transplant, adding PRP to your treatment plan is one of the highest-value upgrades available — a few hundred dollars for a meaningful boost to your surgical results.
Why Colombia for PRP?
The cost difference is the primary draw. In the US, PRP is almost never covered by insurance and runs $1,000 to $1,500 per session — making the recommended three-session protocol a $3,000 to $4,500 commitment before you even start maintenance. In Colombia, the same three-session protocol costs $800 to $1,200 total, using the same centrifuge technology and injection techniques.
For patients combining PRP with a transplant, the savings compound. You're already in Medellín, already at the clinic, and the add-on cost is marginal compared to the standalone US price.
