No you're not asking too much. If the IC shampoo has a sulfate in it, you're basically using detergent to wash your hair. If the conditioners have silicones in them they could be drying out your hair. IC hair polisher is nothing but cones - this one "Cyclopentasiloxane" is the worst. Silcones form a barrier to moisture, which may be fine for hair you want to stay straight and protect from humidity, but they are death for textured curly hair.
Suggest you wash your hair once more with a sulfate-containing shampoo to get those cones out (check that your shampoo has no 'cones).
If you want to stay with drugstore brands there are lots of choices that don't have cones and mineral oils/paraffin or heavy waxes. Here are some that have been recommended here by similar curlies (I haven't used these but they get good mentions)
Shampoo - Creme of Nature
Deep treatments - Lustrasilk Sheabutter Cholesteral -- or mix coconut milk/cheap conditioner/pure castor oil/pure coconut oil or extravirgin olive oil/honey - makes a great deep treatment
Conditioners - Trader Joe Nourish, Suave naturals (Citrus Smoothie) V05 Vitaburst or Moisture Milks - add a little pure oil and/or honey for more moisture
Leave-ins - Aussie 3-minute miracle actually looks good as a leave-in. Generic PM the conditioer is too.
Gels - not familiar with Prostyle, but some good drugstore gels - LA Looks Sport, CHE Body Envy or Set Me Up, Ecostyler (heavy; little goes a long way), Citreshine. Aura Flaxseed.
Ditch the IC Hair polisher (maybe you can use it as a shoe polisher) - that stuff is not good for hair. Use natural oils, butters or pomades on your dry hair for shine. You can use a little castor oil rubbed on your palms and scrunched in your hair to seal your ends
