Aloe vera and honey are potent humectants, perhaps you are overdoing the moisture? Hair doesn't need loads of water to be healthy or for definition that is a common misconception. Hair needs a modest amount of water, too much swells the hair, raises the cuticle, makes it dull and frizzy. Shiny hair has the cuticle laying flat, any damage has been patched by ingredients such as silicones or hydrolysed protein, ingredients that coat the surface can also increase capillary adhesion between strands which helps with clumping and curl definition.
You may well not get instant gratification from Curly Girl friendly solutions, this is about playing the long game. Silicones are the main ingredient that give instant results, faux shine and slip. I can't understand why you would consider water soluble silicones but be against hydrolysed protein which is arguably more natural!
Sorry but natural oils do not achieve the same results as hydrolysed protein they have completely different properties. OIls are occlusives/ anti humectants/ sealers, some can penetrate reducing porosity and increasing elasticity. Hydrolysed proteins are film formers, patch repair, encourage the cuticle to lay flat, strengthen, weak humectants, curl boosting. I use and recommend both for different purposes at different times.
Gliss Kur ultimate volume ingredients: actives of natural origin emboldened, all backed by published research. Keratin is the main protein found in skin, hair and nails, collagen is also abundant in the human body in skin, bone and connective tissue, panthenol is AKA pro-vitamin B5. The remainder are fairly standard emollients, pH adjustors, preservatives, thickener, fragrance many of which are found in haircare products marketed as natural.

I highly recommend reading the Natural Haven blog and the 'curl chemist' articles by Tonya McKay here on NC, they explain what different ingredients families do to hair and there is plenty on the science of natural ingredients as well as some highly effective artificial ones.
