It depends on how you have the straightening done. You need to find a professional on hair straightening if you want it, and be very careful when you do it at home. At home you should brush your hair 100 times after you get out of the shower and then use a straightener meant to turn wet hair straight. Then put in a very strong holding hairspray.
As always, it really depends. I don't know why you would want to straighten thick, curly, healthy hair when it is so beautiful and chic anyway.
You can't get "rid" of curly hair! You are born with it. There are methods of straightening with a straitening iron or chemically. But chemically straightening your hair doesn't work well and does a great deal of damage.
If you mean having a semi-permanent chemical straightening at the salon, you should wait at least 48 hours or longer. You can then go back to your regular washing schedule, and your straightened hair will last 3 or 4 months.

Straightening your hair too much can cause permanent damage to the hair, and can give the hair a straight frizzy appearance. The first thing to do to repair this damage is to get a hair cut. Once the hair is cut, start using deep conditioning therapies on the hair to improve the hairs texture.
You use what is called a straightening iron. It is recommended to use heat protection since it will not damage your hair as much. For more information, visit your local hairdresser.

If by straightening you mean with a flat iron then no, it won't cause your hair to lose curl.

Why would you want to do that? Straightening is to make curly hair straight; perming makes straight hair curly. Doing both in the same procedure would just destroy your hair. If you're trying to turn your tight curls into loose ones, having your hair relaxed is the way to go.
