The extensions are clip-in and straight. This is from the site: "The Euronext Remy Clip-in 14-Inch Human Hair Extensions Package contents include: one 8" wide weft, one 7" wide weft, one 6" wide weft, one 5-3/4" wide weft, four 1-1/2" wide weft, two 1" wide wefts with no snap clips attached (for color testing)." Each weft seems very thin, but I've never used extensions before. So they might be normal. They were very silky when I first got them which probably contributed to my problem. Washing them has helped with that. My hair is straight, and I would say the thickness is average. It's not super full, but it's also not too thin. It holds a curl very well.
I did stop at Sally Beauty yesterday with the extensions in. The clerk, who is a stylist, told me I needed to start the bottom weft closer to the hairline on the back of my neck. I did try this. However, the 5 3/4" is too wide to clip there. I can clip the middle clip of it low enough but then have to angle the ends up. By lowering the wefts and putting them closer together, I do end up with a lot of my natural hair left on top over the top weft. I can't get this to blend right. The clerk suggested I pull that part of my hair up in a clip until it grows more. I don't mind doing that but didn't really want to have to wear it like that all the time.
Thanks!
