I don't know what to tell you. I know that hormones play a big role in your hair when you have a baby. after my second child my hair curled up so much more than it had ever been. But not until after the baby was born. My youngest is going to be three in July and my hair is just now starting to go back to what it used to be. Going CG couldn't hurt. It's worth a try. For me it helped a lot with the frizz and it feels much healthier. Finding the right products helps a lot too. Unfortunately, that takes a lot of experimentation and I'm still not there yet.
What shampoo are you using? What other products?
