PTT-6 for Androgenic Alopecia
PTT-6, a form of autologous platelet concentrate therapy, shows promise as an effective treatment for androgenic alopecia, particularly when used in combination with conventional treatments like minoxidil, but it is not currently FDA-approved and should be considered as a complementary rather than first-line treatment. 1
Current Evidence-Based Treatment Options
The treatments with the strongest evidence for androgenic alopecia are:
First-line treatments (FDA-approved):
Second-line/adjunctive treatments:
PTT-6 Specifics
PTT-6 is a specialized form of autologous platelet concentrate therapy that:
- Can significantly increase hair density and thickness 1
- May decrease the proportion of telogen (resting phase) hairs by up to 9.3 times 1
- Can increase hair shaft diameter 1
- Works best when combined with conventional treatments like minoxidil 1
Treatment Protocol
For optimal results with PTT-6 and other platelet therapies:
- Recommended regimen: 3-5 treatment sessions at 1-month intervals 1
- Maintenance: Sessions every 6 months 1
- Evaluation metrics: Trichoscopy, global photography, hair counts, and diameter measurements 1
Comparative Efficacy
- Minoxidil and finasteride have the strongest evidence base with multiple randomized controlled trials supporting their efficacy 2, 3
- PTT-6 and other PRP therapies show promising results but have less robust evidence compared to FDA-approved treatments 1
- Combination therapy with minoxidil, PRP (including PTT-6), and microneedling may enhance efficacy 1
Patient Selection
PTT-6 may be most beneficial for:
- Patients with mild to moderate androgenic alopecia 1
- Those who show early response (25% improvement in hair density index at 2 months may predict sustained response) 1
- Patients who have had suboptimal results with first-line treatments 1
Important Considerations
Rule out underlying conditions before starting any treatment:
- Check thyroid function, iron stores, and vitamin D levels 1
Treatment expectations:
- Results typically take 3-6 months to become noticeable
- Maintenance therapy is required to sustain results
Cost considerations:
- PTT-6 and other PRP treatments are generally not covered by insurance
- Multiple sessions are required for optimal results
Pitfalls and Caveats
- PTT-6 is not FDA-approved specifically for androgenic alopecia
- Treatment protocols can vary significantly between providers
- Results may be inconsistent due to lack of standardization in preparation and administration
- Patients should continue FDA-approved treatments (minoxidil, finasteride) even when using PTT-6 for optimal outcomes
For severe or treatment-resistant cases, hair transplantation remains a permanent solution, though medical therapy should be continued post-transplant to maintain non-transplanted hair 1.
