4. Dull, Dry Skin
It could mean deficiency in omega-3 fatty acids. Omega-3s are famous for their health perks: They support brain function, reduce inflammation, and can help lower the risk of heart disease, cancer, and arthritis. They also play a vital role in skin, strengthening cell membranes and regulating cell turnover, which ensures skin stays hydrated and radiant.
A deficiency can slow the natural exfoliation cycle, resulting in dryness—even dandruff. The best way to get omega-3s is from your diet. Eat plenty of salmon, sardines, flaxseeds, walnuts, and soybeans, all of which are rich in fatty acids.
