It is helpful in terms of defrizzing, making my hair soft, and saving time, but I don't find that it enhances my curls as much as a gel does. Because curl enhancement isn't my biggest concern, that's fine for me, but if your really looking to make your hair curlier its not going to do much of that. Protein is definitely the most important factor in my opinion though, if my hair needs protein, gel doesn't help that much.
