Collagen

There`s been a lot of buzz surrounding collagen, and according to both Pritchard and Haber, it`s one of the very best things to incorporate into your diet for hair growth. "Collagen gives skin its elasticity, hair its strength, and connective tissue its ability to hold everything in place," says Pritchard. "Our bodies produce collagen naturally, but it declines as we age, so it`s important to supplement through diet." Organic bone broth or powder forms (that you can mix into smoothies or oatmeal) are great options.
