About a year ago I fryed my hair can I now put a perm in it?

I wouldn't recommend it, just leave your hair the way it is. If it's been fried once then it's most likely still damaged...

How does it feel? Is is it dry? Do your ends split easily?
If your hair feels damaged its more than likely that it is so take the initiative a bit with this one.
Drop in to the local hair salon and ask their opinion - its free :)
