Can bleaching straighten one's hair?

I posted this topic to the Hair Color forum, but it seems likely that people in this forum would be more interested in the subject. I hope my copying this post here violate forum ethics too much.

I have a friend who used to have really curled up and frizzy hair and when he bleached his hair, it seemed to become more straight-like: the curls were largely detangled and the hair seemed to grow closer to the head (less frizz).

Of course, bleaching won't make my hair straight straight per se, but it seems like it might make it more managable. You see, my hair grows "horizontally positively," meaning, it's not all that curly, but nevertheless super frizzy and it won't submit to any combs.


Any thoughts on the subject?

well my hair texture before i started coloring was fine, think and very wavey.
After years of coloring and bleaching my hair has lost all its curl. i supose you could say it is no chemically straight. about 6 years ago i cut it all off ( buzz cut ) and started over. as it grew out my curls were in fact still there but  i have since bleached and severly fried my hair and when air dried it is  damn near pin straight
