There are lots of factors that should be considered before selecting long haircut styles.
You have so many styles to choose from, but this does not mean that all of them would be ideal for your specific facial shape and character. The style that you choose needs to be based on which style best flatters your facial characteristics, your personality, and the amount of time you have available to maintain the style. In most cases, those with heart-shaped faces or oval faces have the highest number of choices in the long haircut that is flattering. The long, wavy tresses focus the facial area and add more to the overall styles.
Cuts and styles for lengthy hair are readily available. For instance, a thin face girl with a large forehead needs to ideally leave her hair loose and set the hair in curls. Fringes and bangs can be used to cover the forehead. For any thin face woman, complete straight haircut isn't going to look suitable. It would be wise to work on some balance and symmetry. Middle-parting needs to be avoided by those with long sharp nose. Haircuts must always do justice to the chin and width of the shoulders.
