I think I just decided I will not be envious of curly hair. It sounds so much work. Mine is your typical Scandinavian blond. Extremely fine and thin, very straight, even the perm will not really stick. And if you make curls yourself in any method, they may look nice after lots of work. But if you even consider going outside or kitchen with something boiling or in fact moving, you can be sure next time you look the mirror, you have straight hair again. No use to even tye it, because in two weeks you look like you have bald spots (and if you try to dye roots often enough not to have that 'balding effect' you can be sure your hair will get mad at you and turn to dirty tricks.)
So I have given up. My hair simply is more stubborn than I am even though it looks deceptively fragile. Good thing is, that when I don't bother it, it returns the favour. So I basically wash it (often at night and let it dry when I sleep), show brush somewhere to it's direction almost every day (or at least few times a week, I can't remember when I would have had a tangle that didn't involved either bubble gum or resin) and pin or tie it up or let it be. It can be little stubborn with tying and pins and is a quite an escape artist, but I can be cunning in that battle too. And play dirty and for example re-tie or -pin it middle of the day often.
