I don't think I've had a lot of students who did not have some issues with head voice. Either it's hard to get into head voice, or it's hard to get out of head voice. Then there are the transitions between head voice and chest voice, the different spaces when singing more classical or popular music, and expanding the range to the top. Whatever the case may be, head voice is an important part  of your voice and should not be neglected. Just like strength training for a muscle should not happen without also stretching, it's important that you train your voice on both ends of the spectrum on a regular basis, both high and low.  Only then will you achieve maximum flexibility, strength and accuracy - and that's what every singer needs to be working on throughout their singing career. There are some facts I want you to be aware of so you can be the master of your head voice, and not let it dictate what you can and cannot sing!
