Aria Beauty Slim Straightener Lightweight Prestige Hair Styler not only curls, straightens, and waves in one pass, but it's sleek enough to fit your bag to take you anywhere! Ionic technology gives instant soft and shiny texture to all hair types and textures. How do I use it: Section hair. Take a diagonal section of hair from your ear to the nape of your neck. This will help maintain volume and ensure your roots don't fall flat. Straighten first section. Continue to straighten. Continue to straighten your hair in diagonal sections until the entire head is complete. For curls or waves hold your flat iron horizontally. Place a small section of hair between the plates. Twist the flat iron upwards for the first wave/zigzag. Glide the flat iron keeping the end of the previous wave as the initial point of the second. Twist the flat iron downwards. Keep doing this consecutively to achieve curls or crimps. From Aria.
