Straightner !! HELP!!?

if you have really dry hair then i suggest parting your hair in small sections so you can get smaller pieces at a time , that way is more effective when u want straight hair ! and my hair's super wavy too, but its not that dry so i go down kind of slowly but not too slow so i dont burn my hair, it also helps getting it straighter:) also if your straightener is old i would suggest getting a new straightener ! haha :)
