How about a hat? Why not try a ball cap during the day, with your hair in a pony tail underneath it? Seems better than shaving your head?
You can also try an early discipline technique. When your daughter pulls your hair, put her down and leave her for 1 minute. This is considered a mini time-out and is appropriate for babies under 1 year. They also recommend this for nursing moms who are bitten by their babies who have new teeth. If you do this every time she pulls your hair, you are sending a consistent message that this not acceptable. Be sure to put her down somewhere she'll be safe, like a pack and play. Not on the bed where she can roll off!
Good luck,
