I like Burt's Bees Avocado Butter. I actually slather it on my hair in the morning and wash it out at night. Or, I'll make my own deep condish mixing coconut and jojoba oils and also leave it on all day before washing it out.
For leave-ins I'll use either Jessicurl Too Shea
! or Dr. Bronner's Lavender Leave-In. Most curlies say these are too heavy, but my thick 3C-4A curlinkies drink it up and are left shiny and bouncy!
