you can always tell her it's the wrong season for head shaving. i did mine in november in phoenix arizona, and i still froze my scalp. your daughter is gorgeous, and if she gets dreads i definitely want to see. once i have a child... long as that will be from now... i want to let them have locks from birth. they can decide as they grow how they prefer their hair. that's only if my indecisive ass can get and keep dreads though. and as someone else said... kids that age know what they want! maybe not all the reasons behind it. but their interests in things are often more pure than adults... they have less to complicate their minds with, when considering a choice, so it's easier for them to make.
