I am watching the news and everyday I see women with hair that seemed to grow overnight . I realize they are hair extensions . I can tell for - hair doesn't grow overnight and I watch theses women everyday . 2 - I can tell by the ends cause they are more blunt , and just a different texture . 3 - sometimes obvious where there hair ends and extensions start . I'm not saying they don't look good , just wonder why they feel the need I guess . I also wonder if they clip in , which I would hate having all over my head seems would be uncomfortable , or are there all different styles to apply them for lack of a better word ?
