It depends on the type of layers:
* Long layers: These can create a more elongated look, which can make a round face appear slimmer. If the layers are cut to frame the face, they can further draw attention away from the roundness.
* Short layers: These can add volume and width around the face, which could potentially accentuate the roundness.
* Choppy layers: These can add texture and dimension, but if not styled carefully, they could also emphasize the roundness.
Other factors:
* The length of the hair: Longer hair can naturally make a face appear slimmer than shorter hair.
* The style of the haircut: A haircut that adds volume to the crown of the head can create a more balanced look for a round face.
* The placement of the layers: Strategic placement can help to accentuate the cheekbones or elongate the face.
* The overall hair texture: Fine hair may benefit more from layering than thick hair.
Instead of focusing on "lots of layers," consider these tips for making a round face appear slimmer:
* Ask your stylist for a haircut that creates volume at the crown and frames the face.
* Avoid styles that add width at the sides of the face.
* Consider using a volumizing product to create lift at the crown.
* Try side-swept bangs to cover part of the forehead and create an illusion of length.
Ultimately, the best haircut for you depends on your individual features and preferences. It's always a good idea to consult with a stylist who can give you personalized advice.
