Here is an awesome quote posted by Nova on another thread. This confirms what we have been discussing about the protein and hair. :

Something you stated in your message triggered our memory. It was about taking omega-3 supplements. My oldest daughter grew her hair from shoulder length to the middle of her back. She loves fish and used to eat salmon at least 4-5 times weekly. Plus, she drank every morning, a tofu smoothy with a scoop of soy protein powder in it. In addition to this, she faithfully took vitamins on a daily basis. Since she's slacked in her regime, she's lost approx. 4". To us, daugh. #1 hair is still long, but not long enough by her standards. Daug. #1 states she's going to resume her regime. Daugh. #2 will follow.
