Hair care goes beyond topical treatments; a healthy diet and cutting bad habits can also do wonders for hair loss. Incorporate an ample amount of vitamins, minerals, and protein into your diet. Focus on foods rich in zinc, omega-3 fatty acids, and iron, as they have been proven to promote healthy hair growth—eggs, spinach, and salmon are just some of the many delicious options worth exploring. Keep in mind that smoking and excess alcohol consumption also lead to damaged hair, and can render your efforts towards healthier eating less effective. Both substances affect your body's circulation, preventing your body from absorbing essential nutrients.
