The best way to make straight hair curly involves testing the various options to see which works best. Sponge rollers and making tiny buns are two ways to get curls without involving heat. Using a curling iron is one of the easiest methods for getting various sized curls. These three methods create temporary curls while getting a perm is a semi-permanent method.
Foam rollers, also known as sponge rollers, can help with making straight hair curly. The hair should be slightly damp when starting. Take a small section of hair that fits evenly into the roller, then start from the tips and roll the hair up until it gets to the roots. Put the roller lock in place, then continue doing the rest of the hair. Sleep with the rollers in overnight if possible; otherwise, leave them in for several hours.
Another option for making straight hair curly is to create small twisted buns. Starting at the center part, grab a small section of hair and twist it from root to tip. When the piece is completely twisted, start wrapping it around the base of the section until there is a small and tight twisted bun formed. Secure it in place with one or two bobby pins, then continue the process until all the hair is in little buns. Leave it in for several hours so the curls have a chance to form.
A curling iron is the quickest way to make straight hair curly. The larger the barrel of the curling iron, the larger and more loose the curls are going to be. Put the hair up in a hair claw to start working with the hair underneath. Grab a small section of hair, and while holding the curling iron open, hold the tip of the hair and wrap it around the barrel. Leave it in place for at least ten seconds, then release the curl without pulling it.
Getting a perm, which is a chemical treatment performed at home or by a stylist, is an additional option for making straight hair curly, but not everyone is a good candidate for it. Those who have very thin or extremely damaged or processed hair may want to refrain from this option, as it could damage the hair further or not even take as well as expected. The process takes approximately two hours but it takes around a day for the perm to fully set. It will last about six months, at which time the process will have to be repeated.
While the hair is still straight, use mousse specifically meant for forming curls. After the curls are in place, use a shine serum or finishing creme to help keep them from frizzing. Flip the hair upside down and spray underneath with hairspray, then flip the hair back over to spray the top.
