Curly Sue has nothing on sisterlocks

The curler set you see was created with lock loops.
Pros:
-Curls hold fabulously
-Easy to sleep in
-You can create tight curls or loose curls

Cons:
-You cannot leave the house with lock loops in your hair
-The longer your hair is the longer it takes to dry (12 hours for my hair)

It has been my experience that my curls last approximately 1 week. Of course they become looser as the days pass. I love this style.
