Cnidaria are diploblastic animals; in other words, they have two main cell layers, while more complex animals are triploblasts having three main layers. The two main cell layers of cnidarians form epithelia that are mostly one cell thick, and are attached to a fibrous basement membrane, which they secrete.
Castor oil is known to help keep split ends under control when used as a conditioning treatment. This is due to the many nutrients contained in castor oil, including vitamin E, omega-6 fatty acids, and essential amino acids that can help to penetrate dry and damaged hair.
Hair: Black, Other, Other. Eyes: Brown. I don't use the Jamaican Black Castor Oil brand but just regular castor oil. I do a hair mask every 2 weeks or so. I am careful to only put castor oil on the roots of my hair (cause it's difficult to wash out) and a mix of coconut and argon oil on my mid and end section.
