Intelli-Plant™ Science.

Rebuilding baobab plant protein (hydrolyzed adansonia digitata seed protein) is a botanical alternative to dimethicone. A protein derived from the seeds of the African baobab tree, it helps make hair more resilient by supporting the protein matrix, increases moisture and improves elasticity. It also helps protect hair from chemical, UV and heat stress; enriches and rejuvenates with amino acids for frizz control; and leaves hair softer, smoother, and more manageable.

"My hair feels light and soft! This is unusual for me as when I try leave-in conditioners they mostly leave my hair feeling heavy and filmy. I am amazed at the condition of my hair after one use."
