I love love love your pixie! It's amazing!

I'm trying to decide whether to go for a super short cut right now. It's really hard. I'm dreading the possibility of getting triangle head...but I'm so tired of my wavy thick frizzy hair.

But this gives me some hope!!
Any advice for avoiding triangle head?
