How to Know the Best Wig Length for You?

1. Measure your hair. Take a ruler or a measuring tape and measure the length of your natural hair from the crown of your head to the ends. Note down the measurement in inches or centimeters.

2. Think about the style you want to achieve with your hair extensions. Do you want to extend your hair to the shoulders or mid-back? Or add a few inches to your natural hair length?

3. Consider your face shape

• Round face: Avoid too much volume on top, and opt for longer lengths 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 can help soften angular features.

• Heart-shaped face: Balance a wider forehead with longer lengths 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.

The key factors to consider include your height, natural hair length, face shape, hair bundle texture, style requirements, and budget. If you're still unsure, consult with a hair professional or stylist. With a wide selection of human hair supplies wholesale, Honest Hair Factory is happy to help you.
