Final answer:
For a round face, the best hairstyles are those that add height and create angles to elongate and slim the face. Layered cuts, side partings, textured ends, and high updos are typically flattering. Avoid all-around volume as it can emphasize roundness.
Step-by-step explanation:
The best hairstyle for a round facial type is one that adds height on top to elongate the face, creates angles to break up the roundness, and incorporates volume at the crown. Layered pixie cuts, long layers, side partings, and asymmetric styles can work well. High updos and ponytails also add the illusion of a longer face, while long, straight styles can help the face appear slimmer.
Avoid hairstyles that are rounded or have a lot of volume at the sides, as these can accentuate the roundness of the face. Instead, opt for styles with off-center partings and textured or angled ends. Some hairstyle examples for round faces include a layered bob, a shaggy lob, or a choppy pixie cut with angular bangs.
