I don't really do much to my hair in terms of styling and have it straight most the time, but I do like to add loose waves from time to time when my hair is flat and looking lifeless.
I like using my straighteners rather than curling tongs to get a smoother finish and I only use a few products. My curls last until the next day when they become like beach waves for a slightly different look.
I like to put curls in my hair after a day or two of washing, preferably in straightened hair, which allows the hair to glide through the straighteners to effortlessly create the waves.
Ive put together a video to show you all how I achieve loose waves which adds volume and texture to the hair. I hope you enjoy!
