Well, want no more! Head over to hp_angstfest and check out maidenform's White because oh my lord.
It's rated R, but lordy! The angst and the prose! The turn of phrase in this fic is amazing. For example:
The white hair churns and fizzles, gleaming like a diamond but brighter, more radiant than the purest gemstone or the largest sun. It is wind and water and light, clear waves on the sands of sin and demise, gashes on pure and innocent skin.
I don't think you'll be disappointed. Make sure you leave lots and lots of feedback.
