HAH! I wondered how they came up with that ridiculous hairstyle Will Ferrell wore in Zoolander! 
Klaus Nomi. Length and volume isn’t everything.
I am on an iPad and my attempts to link to Google searches don’t feature the pics I want. Google Greg Giuffria and the band Angel. What do I win? 
Fun fact: Giuffria ended up become a millionaire businessman focused on gaming and casinos.
I once saw Toyah Wilcox on Never Mind The Buzzcocks and during her song “I Want To Be Free” she started head-thrashing. When she stopped, her hair still looked amazing - it was impressive as hell.
My vote is Annabella Lwin of Bow Wow Wow. Others may have started the Mohawk, but no one has worn one better.
I’m surprised nobody has mentioned Peter Frampton.
Tina Turner, absolutely iconic hair
Dolly Parton

Pretty sure those are both wigs.
Dolly wears wigs, in almost all public contexts since the '70s.
Don’t link to Google searches, that looks lazy and usually undercuts the point by including counterexamples and irrelevancies. Link to the specific images that show what you want.
Young Nick Cave.
Well, we can’t have that 
Here you go: Angel - Angel CD. Heavy Harmonies Discography
I have to third(?) Crystal Gayle. I’ve wondered how she manages to wash and dry all of that in less than a week for a very long time.
Well, that is fabulous. I guess you could produce at least two complete Chewbacca costumes with all the band’s hair.
I always loved Jack Casady’s hair, in his prime years. He should have his picture in Funk & Wagnall’s next to the definition of “hippie.”
Young Jorma had some nice locks, too.
You’re not wrong. Mind you, Bowie hair could be a thread in its own right. The man just had a great barnet.
Annie Lennox, obviously.
You spotlighted the wrong photo.
Roger Daltrey 
This actually is against the known laws of physics. Don’t tell me there’s any amount of hair spray that could keep that, er, thing up. That weighs tons! I call fake :D.
