how to measure your hair length
To measure the length of your hair…… Place the end of the tape measure at the front hairline. Lay the tape across the top of the head and let it fall down the back. Note where the hair length ends. It’s easier if you have a friend to help you.
This may not be the most accurate way to measure the actual length, but it’s the most consistent way which is important if you’re trying to mark your hair’s growth.
