Steep learning curve [SEP] I tried these with several other bridesmaids to see if they might make our hair easier on the morning of the wedding. I'm glad we did it ahead of time, because they would have been a wedding morning disaster.<br />First of all, the pictures show these straightened to make waves and the package of ones I received cannot be convinced to hold that shape. This wouldn't be a big deal, except they are difficult to put on as spirals. You have to thread the hook through first, but the tube is much longer than the hook. If I'd been capable of sprouting a third hand, putting these on would have been the moment it happened. And that's only the first hurdle.<br />It takes some extra work to get a good curl out of these. Make sure your hair is damp when they go on or it won't hold the curl (after a lot of success in my life using regular foam curlers on dry hair, this was the most disappointing thing). Keep a spray bottle handy, because they take long enough to put on that your hair will dry before you get done, at least the first couple of times. Make sure the hair isn't tangled or twisted or it won't curl properly. Don't snag your hair section with the hook or you'll find out.<br />A good curl cream is a must because these don't make a curl that holds as well as-- pick a standard type of curler. Make sure you have a God hair spray to set them with, too. If you don't have a quality product or three in your hair to force the curl to hold, they will fall within a few hours and then you've got whatever your hair texture is with too much brushing and a few weird bends.<br />Also, these pull your hair at the root pretty hard if you try to sleep on them loose, so make sure you have a good cap/bonnet/kerchief/babushka (whatever hair covering you use) to keep them arranged into something fairly comfortable.
