Interesting...I can't use some of these ingredients, but I've highlighted what seem to be the growth-related ingredients (they claim the growth comes from amino acids & herbs). The other ingredients are emulsifiers, preservatives, things for the texture of the product, fragrance, etc.

Caprilic/Capric Triglyceride is made from coconut oil, an all around great hair ingredient- might also have an effect.
