While this hair may be a little more involved than your usual routine, it is an easy special occasion hair that delivers maximum impact! Because heat exposure is at a maximum with this technique, it is really important to apply a good heat protection before you begin. Additionally, when you prep the hair with this mouse setting spray, your wave will hold all night long! A note about these extensions: they are not real hair but they would fool anyone! They’re an incredible price for special occasion impact. Just don’t use heat on them! LTKBeauty
