Drusilla:
	This was what Dru's hair was like when she was human.
	Back in the day Dru's hair was a lot more curly.
	In season 2 of BtVS her hair was straighter.
	Then it got curly again...
	Straight again, just in time to re-turn Darla.
	Towards the end of season 3 of Angel her hair was a lot straighter and sleeker.
