I cant clump my curls with a comb or a denman, it disturbs my pattern by poofing my hair into a cloud of hair. In order for my curls to clump I have to rake a styler into my hair in sections with my fingers. Thats it. To seperate the curls a little I lightly shake and go about my business.
I use a leave in on freshly washed hair , then castor oil or Qhemets Biologics Olive and Honey Hydrating Balm, then my Styler. A styler usually has aloe , or aloe vera gel based which leaves my hair a little crunchy , so the oil usually keeps my hair nice and soft yet still defined.
