"Just fantastic regrowth in areas where I desperately needed it." — LaDonna L., Beta Tester
"It worked so well! No irritation and dried without leaving a residue." — Jodi F., Beta Tester
"This is a real solution. Others promise. This delivers. I can only imaging what I'd have to pay to have this in my daily routine—and yes, I will pay it. After a certain age, you pay what you must—not to look younger, but to look your best." — Queen E., Beta Tester

The science behind OS-01 HAIR
Emerging research shows that senescence in hair follicles is linked to age-related thinning, stress-induced thinning, and pattern balding. 03-08
New research also shows that reducing senescent cells in hair follicles can stimulate regeneration.10,11 That's how our OS-01 peptide, proven to decrease cellular senescence in both hair and skin models, targets hair loss and thinning at its source.02,09
To test OS-01 HAIR’s ability to address senescence, our scientists treated senescence-induced cells with OS-01 HAIR. The results showed significantly reduced senescence levels, making OS-01 HAIR a promising candidate for addressing a key biological process linked to hair thinning and loss.03-09
