No. Unless you’re malnourished, eating more steak or other protein won’t significantly affect your hair growth. For your hair to grow you need to be free of disease, have your stress under control, and eat a well balanced diet.
Iron and biotin are essential for hair growth. If you’re a vegetarian or you don’t have a healthy diet, then consider iron and biotin supplements. And if you smoke, even occasionally, stop.
