Here are some of the best heatless styling tools for synthetic curly bob wig with bangs:

1. Rollers and Flexi Rods
- Bendy Rollers: These are great for creating tight or loose curls. Dampen the curly bob wig with bangs slightly with water, section the hair, and wrap each section around the roller. The smaller the roller, the tighter the curl. Leave the rollers in for a few hours or overnight to set the curls。
- Flexi Rods: Similar to bendy rollers, flexi rods are used in the same way. They are flexible and come in various sizes to achieve different curl types。

2. Braiding
- This is a quick and easy way to curl a synthetic curly bob wig with bangs without heat. Start by dampening the wig, then section it based on the desired curl type. For loose waves, use larger sections; for tighter curls, use smaller sections. Braid the hair and let it dry completely before undoing the braids。

3. Bun Wrap
- This method is suitable for longer curly bob wig with bangs. Put the wig into a high ponytail, dampen it slightly, and wrap the ponytail around a doughnut bun. Leave it to dry for a few hours. The larger the doughnut bun, the looser the curls will be。

4. Headband Wrap
- Use a soft headband to wrap the hair. Start with a slight dampening of the wig, then wrap sections of hair over and under the headband. Leave it to dry for a few hours before unwrapping。

5. Twist and Pin
- Section the hair into small parts, twist each section, and wrap it around itself, pinning it in place with bobby pins. The tighter the twist, the tighter the curl will be. Leave the pinned sections overnight for the best results。

6. 3-in-1 Airstyler
