I haven't ever tried that, but now I want to! I used to put jojoba oil on after my gel but maybe I should've done it before...
Usually I view my "seal" as the ice cold water I rinse with before I get out of the shower.
All sealants aside, I've been wanting to try coconut oil on my hair. Thin density is thin hair texture right? I'm guessing coconut oil doesn't weigh you down horribly? I tried Olive Oil as a treatment once on my hair and it made it limp for awhile, even through a low poo. So now I'm kind of cautious with my oils. I wanted to try coconut as a treatment though (just leave it in for a couple hours under a shower cap before I low poo.)
