When you want to add some curl to straight hair, foam sponge rollers are an easy way to do it. They're inexpensive and easy to find, so just about anyone with straight hair can use these accessories to give her hair more volume and texture. Using these rollers the right way will ensure a head full of beautiful curls every time.
Use the Right Size
Buy sponge rollers in the right size for the curl diameter you want. If you want big, loopy curls, buy rollers that are at least 3/4-inch round. Buy rollers that are 1/2 inch or smaller when you want small, tight curls. In general, the longer your hair, the bigger the rollers you should use.
If you want to add volume without necessarily creating curls, use the largest size roller that your hair can fit around. You don't have to use the same size rollers all over your head. Use large rollers around the front and top of your head and smaller rollers in the back. This creates a high-volume look with soft curls and waves around your face.
How to Use Them
Begin with clean, dry hair. You may find it easier to divide your hair into four sections, working one section at a time while using clips to hold the rest of your hair out of the way. Use a comb or your fingers to create small sections no more than 1-inch wide.
When you place rollers in your hair, roll in the direction you want your hair to fall. Roll the roller underhand if you want your hair to curl under. For culs that flip out and up, roll overhand. To direct curls to one side, position rollers vertically when rolling in the direction you want your curls to go.
You can use paper made for hair rolling with the sponge rollers, but it's not necessary.
The longer you leave in your foam sponge rollers, the tighter and longer lasting your curls will be. Ideally, you should sleep in them. This can be uncomfortable for some women. If you don't want to wear them overnight, leave them in for at least several hours to set curls in place.
After rolling your hair, cover with a large satin hair bonnet to hold the rollers in place. When you remove them, unroll them slowly, leaving your curls intact until all of the rollers are out. Comb through your curls with a wide tooth comb to loosen them without creating frizz. After styling, apply hairspray to hold curls in place.
Foam sponge rollers are inexpensive and tend to break down after a while. When you see pieces of foam breaking off of the roller, throw it away. The more hair products you use, especially any that are oil-based, the faster the rollers will break down.
