Just as an FYI...since coconut oil is pure OIL((e.g a fat), if you feel it make your hair hard, it's not b/c of PROTEIN. fat and protein are two different substances sentirely. one issue you are probably having is that pure coconut oil is a SOLID at room temperature. try to use oils that remain liquids at room temperature. there are many to choose from so i'm not going to recommend any. most conventional hair grease products use things that MELT at body temperature, allow them to flow down the length of your hair shaft.
so as you make decisions about what to us, don't falsely equate the basic building blocks with each other.
you can successfully mix it with another oil (remember oil and water do not mix)that is a liquid at room temperature and it will remain in liquid form.
but anything that likes to be a solid at normal room or even body temperature is going to go back to that state and feel hard on your hair.
fats, carbohydrates, amino acids (building block for protein)...all different things. if you dive deeper into organic chemistry or biochemistry, the ingredients on your products make a lot more sense.
