Yes. I have curly hair and when its to my boobs or shorter, it gets super curly, even afro-like. Now its past my mid back and its slightly curly, turning into wavy.
Dont bleach! Buy some amnonia-free hair dye. Dont choose a very light blonde colour. The darker the blonde, the better.
Think theres a 2 week rule leave it 2 weeks and then see how you feel. Remember how much damage bleaching will do to the hair though. Is it really worth having to deal with the damaged afterwards (not to mention root care)?
I would recommend a lightener for very dark hair. I had dark brown hair and used a lightener for black/brown hair every 2nd month and had almost no damage (I guess its impossoble not to damage a bit). After 3 times (1/2 year) my hair was dark blonde ;) I used lightener for black/brown hair every 2nd month. After 3 times (1/2 year) my hair was dark blonde. It got my hair damaged but not that bad. It was dry afterwards but with weekly conditioning it should work. ;) But it really depends on your hair aswell. I have thick hair for example.
I went from medium/dark red brown to a very pale blonde without bleach. Go to a beauty store, get dye and developer (NOT BOX DYE!) and a packet of red neutralizer. Mix it all together as per the instructions and get it on your head quickly.
