Why PRP Hair treatment Works Differently in Different People - Part 1: The General Health Issue

If you’ve been researching PRP for hair loss, you’ve probably come across two very different experiences:

• Someone says it transformed their hair

• Someone else says it “didn’t really do much”

Both can be true.

And that’s not because PRP is unreliable.

It’s because:

PRP doesn’t work in isolation — it works within your biology.

📊 What the Latest Research Shows

A recent 2026 study:

“Longitudinal biomarker trajectories accompanying trichoscopic change after PRP-based regimens for alopecia: a complementary multi-marker analysis of a real-world cohort”

followed 129 patients undergoing PRP-based treatments.

The key findings were:

• Hair density increased overall

• The average improvement was around 12% over a few months

• But results varied significantly between individuals

That last point is the most important.

Because it raises the real question:

Why do some people respond well — and others less?

🔬 Looking Beneath the Surface

This study did something most PRP studies don’t.

It didn’t just look at hair.

It looked at what was happening inside the body at the same time.

Specifically, it tracked:

• Inflammatory markers

• Growth factors

• Vitamin D levels

And it found something very interesting:

As hair density improved, these biological markers changed too

🧠 The Key Insight

Hair growth happened alongside:

• Reduced inflammation

• Increased growth signalling

• Shifts in the body’s internal environment

And importantly:

The degree of these changes varied from person to person.

⚠️ Let’s Be Clear About What This Means

This study does not prove:

• That PRP reduces inflammation

• That PRP increases vitamin D

• That changing these markers will improve your results

What it shows is more subtle—and more important:

People whose biology shifted in a more favourable direction tended to have better hair outcomes.

🧬 PRP Is a Signal — Not a Substance

PRP is often misunderstood.

It’s not like taking a medication where the effect is largely predictable.

Instead:

PRP is a biological signal that asks your body to repair and regenerate.

And your body’s response depends on:

• Your inflammatory state

• Your nutritional status

• Your hormonal environment

• Your overall health

💡 This Explains What We See in Clinic

Two patients can have:

• The same PRP protocol

• The same number of sessions

• The same practitioner

• The same diagnosis eg male androgenetic alopecia

• Similar hair loss severity

And get different results.

Not because the treatment was different.

But because:

The biology receiving the signal was different.

🧠 The General Health Factor

This is the part that is often overlooked.

Your hair is not separate from the rest of your body.

It reflects it.

If your system is:

• Inflamed

• Nutritionally depleted

• Under chronic stress

• Hormonally imbalanced

Then your follicles are operating in a suboptimal environment.

And PRP can only do so much within that environment.

🧬 A Better Way to Think About PRP

Instead of asking:

“Does PRP work?” - it’s does. We have more than enough evidence showing this.

A better question is:

“Is my body in the right state to respond to PRP?”

📈 Why This Matters

Because it changes the strategy.

If you focus only on the procedure, you’re missing half the picture.

If you optimise your general biology alongside treatment, you give your PRP a much better chance of doing more for you.

🧠 The Growth Factor Hair Clinic Approach

This is why I don’t see PRP as a standalone treatment.

I see it as part of a wider process:

• Understanding the type of hair loss

• Assessing the underlying biology

• Supporting the system, not just the scalp

• Then using PRP as a targeted stimulus

🧬 Final Thought

PRP can improve hair density. We know this and it well supported by evidence.

But this study reinforces something important:

The outcome depends as much on the patient as it does on the treatment.

➡️ Coming Next: Part 2

In Part 2, I’ll cover the hair-specific factors that influence PRP outcomes, including:

• Early vs advanced androgenetic alopecia

• Scarring vs non-scarring alopecia

• Follicle viability and timing

Because even with perfect biology…

The follicle itself still has to be capable of responding.

If you’re considering PRP and want a clear, honest view of whether it’s right for you:

• What type of hair loss you have

• Whether your follicles are likely to respond

• What may be limiting your results
