What is the preferred angle when cutting hair with shears for a layered look?

Cutting hair at a diagonal angle is preferred for achieving a layered look because this technique enhances the natural movement and texture of the hair. When you cut at a diagonal, it allows the layers to blend more seamlessly into one another, creating a softer appearance rather than harsh lines that can occur with other cutting angles. This method can also help in adding dimension to the hairstyle, making it visually more appealing.

Additionally, diagonal cuts enable the stylist to manipulate the hair's fall and shape in a way that adds volume and bounce, crucial elements in a layered hairstyle. This approach can also facilitate better control over the length and shape as layers are added, ensuring a more tailored and customized finish for the client's unique hair type and style preference.
