Our synthetic fibers can withstand high heat temperatures up to 180 degrees.
They can be stretched and curled, however when it comes to curling it will take a little longer to get the curls.
Unlike human hair, it is necessary: Hold the curler in the hair for at least twice as long as it takes for the curl to set. Once the curler is removed, don't pull the hair, just slide it off the curler and out of the curl. Let the curl cool down before pulling or styling. Be sure to test a small section of hair to make sure the curling iron isn't too hot.
It is safe to use up to 180 degrees, but for a longer lifespan, we recommend using a temperature up to 110 degrees.
