Just one of my many random thoughts about the shows BTVS and Angel:

Spike always mocks Angel about his hair, and he keeps repeating that Angel uses tons of stuff in it. Like hairgel and such...
I mean is he kidding?!?!?
There is no way in hell that his radioactive colored hair would stay the way it does without A LOT of help!!!
When he is all crazy in the basement in Buffy we can see that without it's daily fix, his hair is a mess! I actually thought it looked better that way;P

So just to wrap it up:

Spike is a hypocrite and Angel has great hair!
