Study information

Our 12-week study of 3.4.4 Capixyl™ + Placenta Shock de Luxe Lotion involved 20 volunteers aged 21–67 with androgenetic alopecia. The general evaluation recorded 90% for hair strengthening, 85% for improved hair regeneration and reduced inflammation, and 80% for healthier-looking hair.

These are general evaluation findings, not measured percentage increases in hair strength or growth.

1.3 Peeling + 3.1 Shampoo + 3.4.3B Lotion
Study information

Our dermatologically supervised study followed 25 volunteers aged 23–68 with androgenetic alopecia over approximately 12 weeks. The results list 96% for promotion of hair growth, 92% for reduction of hair loss, 83% for increased hair density and 100% for overall hair improvement.
