Hi cricket2168, You dont need to get the glued in extensions, especially if you are going to have an up-do. Also, dont worry about getting asian hair, any human hair that is straight will do just fine. What I do suggest is buying a weft of hair and not the clip-ins for your up-do. If you buy a weft your stylist can build volume and has more control. You can absolutley highlight your hair just be sure to take your extensions with you so your colorist can do a color match. Extensions arent usually something I would recommend buying online unless you know exactly what you want. You should always go in and see them for yourself...check the texture, color and density of the extensions.
