3. Consider your face shape

- Round face: Avoid too much volume on top, and opt for longer lengths (18-20 inches) to create a more oval shape.

- Oval face: You can pull off most lengths, but 18-20 inches can create a balanced look.

- Square face: Softer, longer lengths (18-20 inches) can help soften angular features.

- Heart-shaped face: Balance a wider forehead with longer lengths (18-20 inches) and avoid too much volume on top.

4. In terms of maintenance, if you are busy, you might prefer shorter lengths (12-16 inches) that require less maintenance. If you're willing to invest time in styling and maintaining your hair, longer lengths (18-22 inches) might be a better fit.
