I would never, ever have Elena's hair chemically straightened. I don't want to get stuff done to my hair and she's way, way too young in my opinion to have anything done. I am often amazed at the number of girls under age 12 who have coloring done to their hair. If I did allow it (and it's not gonna happen), Elena would freak at the smell, process, etc. anyway.
I did get my hair chemically straightened when I was 25 or so. It burned my skin around the hairline (first ick), took forever, smelled like crap for days and lasted not even 1 1/2 months, if that. Also, never having had straight hair-I freaking hated it, didn't know what the hell to do with it. It always looked flat around my head, when I was used to poofy.
I used some Curl Creme on her hair today and will retry the Infusium also. I just can't stand how it looks, she doesn't care-it just never looks clean and neat to me, even after it's just washed, dry and combed (combed, brushed, doesn't matter).
