Protein will help your hair become stronger. I always had thin hair, then I cut it a lot. Like shaved in the back and long in the front, then it seemed to grow in a lot thicker. Shampoos, so far, have all been a farce. Your hair will become thicker when you are pregnant, and for me it didn't go back to the way it was. So, yay, thick hair.
