Condition
Hair Regeneration
New follicle formation remains a laboratory concept.
Quick summary
- • No human evidence of new follicle formation
Overview
Creating new follicles differs from thickening existing hair.
Mechanisms studied
Dermal papilla cells are studied in the laboratory.
Human research
Not confirmed in humans.
Safety
Reported adverse events are mostly local — swelling, pain, or bruising at the harvest and injection sites. Infection and cell-processing quality remain the key risks to monitor.
Evidence limitations
Existing studies are limited by sample size, methodology, and follow-up, and SVF preparation differs substantially between centres, making cross-study comparison difficult.
