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.
