Use a soft measuring tape and start by flattening down your hair as much as possible so that you can take an accurate reading.
Sit side on to a mirror so that you can see the back of your head - you may find it easier to ask someone else to help you.
To measure the circumference of your head, place the beginning of the tape measure at the centre of your forehead where it meets your natural hairline. Holding the tape in place, feed the tape through your fingers and around to the back of your head, keeping the tape underneath your ear.
Continue taking it down to the nape and then bring it up behind the opposite ear, continuing along the hairline to meet the starting point.
Read off the measurement in either inches or centimetres and take a note.
We recommend taking the measurement twice just to make sure that you make a correct reading as choosing the correctly sized wig will be the most important factor in the overall comfort of your wig.
