Stem cell-enhanced PRP costs $3,000 to $6,000 per session compared to $500 to $2,000 for standard PRP, and the only way to know whether the premium is justified for your hair is to track your density response to both treatments with objective data. This guide shows you how to set up a structured tracking protocol for stem cell PRP using myhairline.ai.

What Makes Stem Cell PRP Different from Standard PRP
Standard PRP (platelet-rich plasma) concentrates your blood platelets and injects them into the scalp, delivering growth factors that stimulate follicular activity. Clinical studies show standard PRP can increase hair density by 30 to 40%.
Stem cell PRP adds adipose-derived stem cells (ADSCs) or stromal vascular fraction (SVF) harvested from a small fat sample, typically taken from the abdomen or thigh via mini-liposuction. These stem cells are combined with the PRP concentrate before injection.
The theoretical advantage is that stem cells provide additional growth factors, cytokines, and regenerative signaling molecules beyond what platelets alone deliver. The practical question is whether this translates into measurably better hair density outcomes for you.
| Feature | Standard PRP | Stem Cell PRP |
|---|---|---|
| Cost per session | $500 to $2,000 | $3,000 to $6,000 |
| Growth factor source | Blood platelets | Platelets + adipose stem cells |
| Fat harvesting required | No | Yes (mini-liposuction) |
| Sessions recommended | 3 to 4 initial | 3 to 4 initial |
| Published density improvement | 30 to 40% | Limited data, potentially 10 to 20% higher |
| FDA approval status | Not FDA-approved for hair | Not FDA-approved for hair |
Step 1: Capture Your Pre-Treatment Baseline
Your baseline is the single most important data point in this entire process. Without it, you have no way to measure what the treatment actually accomplished.
Take your baseline reading with myhairline.ai at least 7 days before your first stem cell PRP session. Record:
- Your current Norwood stage
- The specific zones you plan to treat (temples, crown, vertex, diffuse)
- Your current treatment stack (finasteride, minoxidil, or other medications)
- The date and conditions of your baseline photo
If you have previously tracked standard PRP sessions with myhairline.ai, your existing data becomes your comparison benchmark. This is the ideal scenario because you can compare density response per session between the two treatment types.
Step 2: Track Each Session with Pre and Post Readings
For each stem cell PRP session, create a data point pair:
- Pre-session reading: Take a density reading 1 to 3 days before the session
- Post-session reading: Take a follow-up reading 6 to 8 weeks after the session
The 6 to 8 week gap matters. Stem cell PRP does not produce instant results. The growth factors and stem cell signaling require time to stimulate follicular activity and produce visible density changes.
Build a tracking table for your sessions:
| Session | Date | Pre-Session Stage | Post-Session Stage (6-8 weeks) | Density Change |
|---|---|---|---|---|
| Session 1 | Month 0 | Norwood 3 | Norwood 3 | Minimal |
| Session 2 | Month 1.5 | Norwood 3 | Norwood 2.5 | Improvement detected |
| Session 3 | Month 3 | Norwood 2.5 | Norwood 2.5 | Stable/improving |
| Session 4 | Month 4.5 | Norwood 2.5 | Norwood 2 | Continued improvement |
Most patients see the first measurable improvement after session 2 or 3. If you see no density change after 4 complete sessions with 8-week follow-ups, the treatment may not be producing a meaningful response for your biology.
Step 3: Compare Stem Cell PRP to Your Standard PRP Data
If you previously received standard PRP and tracked those results, you now have the data to make a direct comparison. The key metric is density improvement per dollar spent.
Here is how to calculate it:
Standard PRP value: Total density improvement over your standard PRP course divided by total cost.
Stem cell PRP value: Total density improvement over your stem cell PRP course divided by total cost.
For example, if standard PRP at $1,000 per session over 4 sessions ($4,000 total) produced a shift from Norwood 3 to Norwood 2.5, and stem cell PRP at $4,500 per session over 4 sessions ($18,000 total) produced a shift from Norwood 2.5 to Norwood 2, you can evaluate whether the additional investment delivered proportional results.
For detailed guidance on measuring standard PRP outcomes, see our guide on tracking standard PRP treatment results.
Step 4: Account for Confounding Variables
Density changes during a stem cell PRP course can be influenced by factors other than the treatment itself. Your tracking needs to account for:
Concurrent medications: If you are taking finasteride (which halts further loss in 80 to 90% of users) or minoxidil (40 to 60% regrowth rate), some of the density improvement may be attributable to these medications rather than the PRP.
Seasonal shedding: Hair shedding naturally increases by up to 60% in autumn. A stem cell PRP course that spans summer to autumn may show misleading density dips that are seasonal rather than treatment-related.
Norwood stage baseline: Patients at earlier stages (Norwood 2 to 3) tend to respond better to PRP treatments than patients at advanced stages (Norwood 5 to 7). Your starting point affects your expected outcome.
Keep your medication and supplement stack stable throughout the tracking period whenever possible. Changing multiple variables at once makes it impossible to attribute density changes to any single treatment.
Step 5: Make a Data-Driven Decision About Continuation
After completing your initial course of 3 to 4 stem cell PRP sessions and tracking density at each stage, you have enough data to decide whether to continue.
Continue stem cell PRP if: Your density improvement per session exceeds what you achieved with standard PRP, and the cost premium aligns with your budget. Maintenance sessions every 4 to 6 months sustain results.
Switch back to standard PRP if: Your density improvement is comparable to standard PRP. You get the same results for $500 to $2,000 per session instead of $3,000 to $6,000.
Discontinue PRP entirely if: Neither standard nor stem cell PRP produced measurable density improvement after a full initial course. Some patients are non-responders to PRP regardless of the preparation method.

What the Cost Data Tells You
The financial gap between standard and stem cell PRP is significant across multiple sessions:
| Treatment | 4 Sessions (Initial) | 2 Maintenance/Year | Year 1 Total |
|---|---|---|---|
| Standard PRP (low end) | $2,000 | $1,000 | $3,000 |
| Standard PRP (high end) | $8,000 | $4,000 | $12,000 |
| Stem cell PRP (low end) | $12,000 | $6,000 | $18,000 |
| Stem cell PRP (high end) | $24,000 | $12,000 | $36,000 |
Without density tracking data, you are spending $18,000 to $36,000 per year on faith. With tracking data, you are making an informed decision about whether the premium produces premium results for your specific biology.
