IMO, not a lot of your products are very moisturizing. The SM smoothie is mostly shea butter which acts as a sealant, rather than a moisturizer. So you might need something more to actually moisturize your hair such as a better leave in. I would suggest something with more fatty alcohols. If you want to use the smoothie, I would suggest putting it on last. Also, it could be the reason for build-up which could be pertaining to the frizz and your V05 isn't strong enough to wash it out.
Here are the ingredients to the mousse:
Water, Isobutane, Propane, Polyquaternium 4
, Bambusa Vulgaris (Bamboo) Extract, Cereus Grandiflorus (Cactus) Flower Extract (Cactus), Fragrance, Propylene Glycol, C9 11 Pareth 8, DMDM Hydantoin, Disodium EDTA, Citric Acid
The Polyquat 4 that I bolded, tends to be prone to build-up. Thus, your V05 isn't strong enough to wash out which could also be pertaining to this frizz.
