I have now had this in my hair for 3 weeks. So far OK?! The Black Onyx hair still holds no curls. I redid the invisible part with some Enstyle hair s4/30, so now its kinda orangy. All together 3 types of hair in my head. I also went a head and added some 18in of the Model Model Ikon hair in the back. It's pretty but holds no curls. I now give this a D. Its really pretty right after it's done but...it drops.
