When choosing a silk heatless hair curler, the inner filling material plays an important role in styling results. The two most common options are EPE filled curlers and microfiber filled curlers, each offering different benefits.

Structure and Support
EPE filled heatless hair curlers have a firmer internal structure. This added support helps the curler hold its shape better during use, making it easier to wrap hair evenly and achieve more defined curls. In comparison, microfiber filled curlers are softer and more flexible. They adapt easily to the shape of the head, offering a more relaxed and comfortable styling experience.

Curl Results
EPE filled curlers are ideal for creating more structured and long-lasting curls, especially for users who prefer a defined hairstyle.
Microfiber filled curlers are better suited for looser, natural-looking waves, making them popular for soft everyday styling.

Comfort and Wearability
Because of their soft texture, microfiber curlers are often considered more comfortable for overnight use. EPE curlers, while still comfortable, provide slightly more firmness, which helps improve styling consistency.

Which One Should You Choose?
