If you’re researching PRP (platelet-rich plasma) for hair loss, you’ve likely also come across newer regenerative options — including stem cell-based treatments like ARC+ Therapy. Both approaches aim to stimulate the scalp and slow hair loss, but they work differently, cost differently, and produce different results.
Here’s an honest breakdown of what each treatment involves and what the evidence actually supports.
What Is PRP for Hair Loss?
Platelet-rich plasma therapy involves drawing a small amount of your blood, spinning it in a centrifuge to concentrate the growth factors, and injecting it into the scalp. The goal is to stimulate dormant hair follicles and extend the active growth phase.
Key facts about PRP:
- Multiple sessions required (typically 3-4 initial treatments, then maintenance every 6-12 months)
- Results are gradual — most patients notice changes at 3-6 months
- Most effective for early-stage androgenetic alopecia
- Not recommended for completely bald areas or scarring alopecia
What Is ARC+ Therapy?
ARC+ (Autologous Restorative Cell Therapy) uses a concentrated preparation derived from the patient’s own cells — not just the platelet fraction, but a broader cellular concentrate. At ScalpMasters, ARC+ is prepared and administered in a single session.
In a clinical observation involving patients with genetic hair loss, participants experienced an average hair count increase of 116% and an average follicle diameter increase of 107%. The highest recorded result was a 200% increase in hair count.
* ARC+ Therapy is an investigational treatment and has not been approved by the FDA. Results reflect clinical observations from ScalpMasters’ patient population. Individual outcomes vary.
How They Compare
PRP: Patient’s blood (platelet layer) | 3-4 initial + maintenance sessions | Generally accepted | Best for early hair loss
ARC+ Therapy: Patient’s own cells (broader concentrate) | 1 session | Investigational | Best for moderate to significant thinning
Which One Is Right for You?
PRP is a well-established option with a solid research base, particularly for patients in the early stages of hair thinning who want a low-risk maintenance treatment.
ARC+ Therapy may be worth exploring if you’re looking for a single-session treatment with higher-intensity cellular support, or if you haven’t responded well to PRP. The best way to determine which approach fits your situation is a consultation with a qualified specialist.
