Silicone-Free Leave-In Conditioner That Strengthens Hair With Every Use

 

Most leave-in conditioners coat the hair in silicones. You feel smoothness. You see shine. But the fiber underneath keeps breaking.

 

Under Your Skin's Leave-In Conditioner works differently. Fermented microalgae oil, olive stem cells, and crambe abyssinica seed oil penetrate the hair shaft to strengthen the fiber itself - not mask it. No silicones. No build-up. No compromise.

 

The results are measurable:

  • 83% less hair breakage
  • 62% reduction in frizz
  • 10% improvement in split ends

 

Hair that performs better the more you use it - not just on wash day.
