SASSY Curler our newest patented product can do what you can't even think is possible. Should I use the SASSY curler on wet or dry hair? Either. But since SASSY works just as well on dry hair, we suggest that the hair is dried thoroughly first then misted with hair spray or gel before curling for longer, lasting curls. How long do I need to leave in SASSY curlers? If using the dryer, approximately 10 to 15 minutes. Otherwise, let it dry naturally for 30 to 35 minutes. Longer, thicker hair will require more time. How do I clean SASSY? Soap and water. How many SASSY curlers do I need to create a full head of curls? Average head of hair will require two (2) dozen. Why is SASSY curlers different from any other roller? They can be used on dry hair. Lightweight, foam based curler, soft enough to sleep in. No pins or heat required. Adds instant texture and fullness. Also use as a permanent wave rod. Create a hairdo of your choice in no time, fast , easy and comfortable. Our unique design is patent protected. It's lightweight.
