Can you boost hair, skin, and nail health with diet?

You’ve likely heard the phrase “you are what you eat.” When it comes to your hair, skin, and nail health, there may be some truth to that statement.

A 2019 reviewTrusted Source identified a link between micronutrient deficiencies and cutaneous abnormalities in hair, skin, and nails. Cutaneous abnormalities can include:

• acne
• eczema
• psoriasis
• melanoma
• other skin conditions

In particular, researchers said poor intake or low absorption of certain vitamins and minerals may be the culprit. 

These vitamins and minerals include:

• B vitamins
• fat-soluble vitamins like A, E, and K
• zinc
• iron
• copper
• selenium
• essential fatty acids

Similarly, a 2017 studyTrusted Source concluded that multiple kinds of nutrient deficiencies can result in hair loss.
