My hair is not going to work

UGGGGH, After I washed my Ebay hair it turned very poker straight where my hair has a wave to it. When I put the hair up to my head it looks like I straight ironed some of my hair and left the other wavy - very stupid looking. This hair is also fine Italian hair where mine is a more course Italian hair (most likely because of the wave). I bonded pretty much half of the hair but washed all of it. I think I am going to put it on Ebay and maybe somebody who has VERY straight hair can use it for extensions unless you guys have any ideas for me.

the wave that was in the hair at first was prob. from a braid... ya think?

if you flat iron your hair, would it match better? or maybe perm the pony...

is there even such a thing as "fine Italian" hair??

I'd blowdry it to where it was ALMOST dry, then put the rest into a thick braid in the back, by the time its dry, everything should be slightly wavy.

or blowdry it and scrunch your hands while you do it. that turns even straight hair wavy.

My natural hair is thick and has a nice wave to it. To straighten my hair would take about an hour which I do not have and then as soon as I go outside the humidity will make the waves come back. If I perm this hair it would make it too short. So it's a no to this hair and on to others. I am interested in the plastikhaar and wrote for a sample. I guess I can still donate this hair if I cut the tips off?
