Is there a way to curl hair without damaging it at all?

I heard of people that hot rollers can damage hair and so can curling irons. I have naturally straight hair so any curling products (curling mousse etc.) won't work on my hair. Braiding makes it all frizzy. So is there any other way to get like loose curls without damaging your hair at all?

ANY kind of heat on your hair is going to stress it out! Heat is NOT natural to your hair and without the proper protection, it will damage.

I have thick, long, shiny hair. I rarely use heat on it. Maybe on a Saturday night when Im going out. If you use a curling iron on well moisturized hair now and then, it will not affect your hair much at all. Just give it a good recovery with a deep moisture shampoo the next time you wash to prevent it from becoming brittle.

Go ahead, curl your hair now and then - Its not going to fall out.

Buy using plastic rollers is the best way.
