To get this retro Lived-in Look, prep damp hair with siren waves and a nourishing oil. Use the Dyson Supersonic with the diffuser attachment on high heat, at a low speed. You should refrain from touching the hair as much as possible, until the hair is 80% dry. Continue diffusing, but hold the roots up for some volume. When the hair is completely dry, add nourishing cream from Milbon.
