Profiline Curlers boilable 27 mm 10 pieces large

Remove the plastic grip from the curlers. Place the curlers in gently boiling water. Then boil for 10-30 minutes. NO and then remove the curlers when still hot and after 20 minutes when they start to cool down (time permitting).
As long as you don't get wet, the hair will hold for a long time. I dare say until the next wash. But it's better to put a curling iron in the hair and curl it right after washing. Curlers are also good for curling synthetic hair.
