Not a lot of hair strands and sheds [SEP] PRO: Most of these lasted at least 3 weeks and looked pretty good. I bought medium brown curly strands and oddly, A COUPLE of strands stayed curly but not all. CON: each extension doesn’t have a lot of strands of hair in it. After 3 weeks they started shedding a lot and began falling out. I have about 4 left now.
