The system is as simple as it is brilliant! Without heat you get gently Engelslöckchen. Target in dry and wet hair function. For me it only works really well with wet hair and overnight. Sleeping is therefore no big problem because the curlers are flexible and soft. After 2-3 attempts, the application works without problems and you get really nice curls. The winder also the longest are very short. For my hair (length up to his chest in the middle), a winder is enough for about half of the hair length. Who cares, who can draw winder 2 superimposed without any problems. But even with a winder you get the lower part of the hair curled really nice. Looks great.
