Liz's loops, I haven't tried Dove's luminizing mist, but I have been sampling some things like what you are looking for. Serums work for a couple hours for me, then leave my hair limp. So I also can't use them. But I found the same issue with spray serums, too. Recently I've been using the Body Shop's Brazil Nut Define & No Frizz. Here's the ingredients:

Water, Cyclomethicone, Glycerin, Caprylic/Capric Triglyceride, Sodium Chloride, Bertholletia Exclesa (Brazil Nut) Oil, Dimethicone Copolyol, Oryza Sativa (Rice) Bran Oil, Persea Gratissima (Avocado) Oil, PPG-3 Myristyl Ether, Propylene Glycol, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Rosa Canina (Dog Rose) Hips Oil, Potassium Sorbate, Propylparaben, Fragrance, Methylparaben, Oryzanol, Hypericum Perforatum Extract, Achillea Millefolium (Yarrow) Extract, Panax Ginseng (Ginseng) Extract, Tocopherol, Caramel

Even with Cyclomethicone being the second ingredient, I haven't had any issues with it weighing down my hair, even when I use a lot. But everyone's hair is different, so it's hard to say. They have a very liberal 60 day return policy, so it might be worth a try if you're looking for something to make your curls shinier. I use it over Batia & Aleeza gel.
