My hair is super thin and relaxed... how do I make it look thicker?

I have hair down to the bottom of my shoulder blades. It's dirty blonde and really thin. I'm thinking about a loose perm but I keep hearing about all the ones that get screwed up. I don't want to cut it short for layers. I also don't want it to take more than 10 minutes in the morning. Any ideas?

yes i do. try using volumizing shampoo and conditioner. if you blow dry your hair, blow dry it upside down. and when you brush your hair, flip your head over upside down and brush it that way on the bottom.
