Some tips:
1. If you like softer curls, I recommend you keep the curler in for less time and use setting spray.
2. If you don’t like how tight the curls are in the morning, I recommend brushing your hair through it (maybe with some water) until you get it to the way you want it to look and then put setting spray in.
3. With each new section, I recommend twisting your hair before wrapping it around the curler. It helps the curls a lot.
