I second the CJ Beauticurls leave-in - I love this one. My hair is normal porosity (not low, like yours), so I'm not sure how much difference that will make for you, but I also have fine hair that can also get weighed down. The KCKT didn't weigh my hair down, but it also didn't provide enough moisture (I live in a dry climate). The other leave in I really like is the As I Am leave in (available at Sally's); it's light weight but still moisturizing. I also love Curly Kinks satin roots - I haven't used it as much in the winter because I have to stay away from glycerin, but its a great leave in - not heavy, just the right amount of moisture, good slip.

fine, dense, normal porosity/elasticity, dry climate

My favorite brands are Kinky Curly, As I am, Curly Kinks, Curl Junkie, and Darcy's Botanicals. Also love sealing with oils (loving argan oil right now) and styling with jelly products (KCCC is my current favorite). Mostly trying to keep it simple!
