HEAD MEASURMENTS
For the most accurate results secure your hair in the manner it will be under your wig.
Typically most women either braid their hair straight back in cornrow, or wrap it flatly. Be sure to take your measurements a few times for accuracy.   Use a fabric measuring tape for the best results.

Use our stock wig measurements as a guide if you are unsure of the accuracy.
