New Study: Platelet-Rich Plasma Increases Hair Growth by 24%

A recent clinical study evaluating Platelet-Rich Plasma (PRP) therapy has shown promising results for people suffering from androgenetic alopecia (pattern hair loss). Researchers observed that PRP therapy significantly improved hair density and scalp health in participants after several treatment sessions.

The study reported that patients receiving PRP treatment experienced up to a 24% increase in hair density, along with improved follicle activity and reduced hair shedding.

What is PRP?

Platelet-Rich Plasma (PRP) is a regenerative treatment derived from a patient’s own blood. The blood is processed in a centrifuge to concentrate platelets, which contain growth factors that help repair tissues and stimulate hair follicles.

These growth factors help:

Stimulate dormant hair follicles
Improve scalp blood circulation
Extend the hair growth phase (Anagen phase)
Strengthen existing hair follicles

Multiple clinical studies and meta-analyses show that PRP therapy can increase hair density and reduce hair loss, making it a promising non-surgical treatment for alopecia.

Study Method

The clinical evaluation involved patients diagnosed with androgenetic alopecia.

Treatment protocol included:

3 PRP treatment sessions
Sessions spaced 4 weeks apart
Follow-up evaluation after several months

Researchers measured:

Hair density (hairs per cm²)
Hair thickness
Hair shedding reduction
Patient satisfaction

Key Findings

The study revealed several improvements after PRP therapy:

✔ Up to 24% increase in hair density
✔ Reduced hair shedding
✔ Stronger and healthier hair follicles
✔ Improved patient satisfaction

Previous randomized clinical trials have also shown that PRP injections significantly increase hair density compared with baseline measurements in patients with androgenetic alopecia.

Conclusion

PRP therapy is emerging as a safe and effective non-surgical treatment for hair thinning and androgenetic alopecia. With consistent treatment sessions, patients may experience improved hair density, healthier follicles, and noticeable hair regrowth.
