Yes, a middle part can be a good hairstyle choice for a heart-shaped face.
A middle part can help to create a balanced and symmetrical look for heart-shaped faces. According to stylists, a middle part can "create the illusion of length and gives the look of perfect symmetry for the face." This is particularly helpful because heart-shaped faces are often characterized by a wider forehead and a narrower chin. The symmetry created by the middle part helps to minimize the appearance of a wider forehead by distributing hair evenly on both sides of the face.
In addition to creating symmetry, a middle part can also help to soften the angles of a heart-shaped face. The way the hair falls around the face can create a more rounded and balanced appearance.
Therefore, if you have a heart-shaped face, experimenting with a middle part could be a beneficial styling choice.
