Tip 1:
 
Use a finishing mist with your flat iron to help the hair stay straight. Lightly spray each section first and then follow with the flat iron.
Tip 2:

Use a finishing mist with your velcro rollers to ensure that curls retain their shape. For best results spray the base of each curl as well as the entire curl set.
Tip 3:

To get incredible volume and fullness flip your head upside down and spray the underside of the head both when blow drying and when finishing a style.
