Possible deficiency: Fatty acids
If you notice that you’ve got flakes raining down after you scratch your head, you automatically think dandruff. But it may also be because you’re not getting enough healthful fatty acids in your diet. “Essential fatty acids, like omega-3s, are a lubricant for our body,” explains Staci Small, RD, of The Wellness Philosophy in Greenwood, Indiana. Without it, you’ll go dry. Make sure to eat two fish meals per week to get in omega-3s. Other fatty acids, like alpha-linolenic acid (ALA), are also important. Find these in walnuts and flaxseeds.
