HELP!!!

I need help!!! Ever since Tytan was born my hair has never been the same. I feel like it always looks so fine and flat. No matter how hard I try my usual hair routine is not working. I know a lot of you out there use rockin' hair products or have little secrets that always work. So please give me any little secrets you may have. I know all of you have a couple you want to share with someone in need . Any little thing will help, etc. brand of curlers, flat iron, hairspray, anything. Seriously my hair is in need of something new before I wake up one morning and decide to shave it all off like Brittney.
