hair help/human vs synthetic

I am currently using wawa hair, but it just gets tangled too much. I would love to try the elite thermofiber, but they never have my color. So I would like to get some human hair wefts that I could sew clips on myself, or some with clips already on, The problem is that I want  the hair to be full like the synthetic. Whenever I put human clip ins in my hair, it is still to flat and thin. I like the fullness of the synthetic, but I like to be able to comb my hair and with the wa wa I can't. I can't afford real expensive, but any ideas of brands would be great. Thank you, DEB
