Hi ABCD
I went into this 'head voice singing some time ago
Whether you like it or not is a matter of taste, but the fact that it takes at least twice the breath to produce means it restricts most singers from singing long-lines without having to breath in the middle
The other problem is the dreaded 'gear change where many women are unable to maintain a consistent tone and are forced to move from head to chest when moving up and down their range
The daughter of a well known singer we know has such a limited range that she produces a yodel-like sound if she exceeds her range
Pegt Seeger worked on this at great lenght and more or less conquered it - but did she hane to !!!
