Review (5/5): I buy these all the time. I love them!
My hair is usually shaved or real short. I love using these clip in extensions as a whole wig when I do costumes because I think being able to keep some of my real hair out looks more realistic than a full wig. Anyway, here are some tips: This is my first straight one and it does have kinks in it from being folded..you can dip it in boiling water to knock that out, just lay it flat to dry. You CAN dye these with fabric dyes made for polyester fabrics. If it's curly, you will lose the curl though because you have to boil to dye. You can't lighten dark hair, only light to dark. I like to rub a dryer sheet all over these so they don't get too tangly. This one in particular shed minimally when I was playing with it. It also clipped in well to my hair which is about 2 weeks growth...though it did hurt a little because of the length of my hair, I recommend more than two weeks worth of hair to clip it to and these will feel great and stay put.
