Read and research the ingredients and look at what your hair needs based on its properties and your local climate. The Jessicurl has behentrimonium which is great for slip plus several oils/ butters some of which contain fatty acids that may be absorbed into damaged/ highly porous hair. It is not packed with humectants, the water attracting ingredients, nor proteins if your hair does well with those.
There are loads of great science-based articles here on Naturally Curly by 'curl chemist' Tonya McKay, plus some good stuff on the Natural Haven blog.
