Eggs are rich in protein and biotin, two nutrients necessary for healthy hair growth.
Hair follicles are mostly protein, so getting enough protein in your diet is essential for healthy hair growth. There is evidence that a lack of protein in the diet is linked to hair thinning (1).
Because biotin is required in the synthesis of keratin, a protein found in hair, biotin supplements are commonly marketed for this purpose. Extra biotin in the diet has been shown to stimulate hair growth in those who suffer from biotin deficiency.
Deficits in biotin are unusual, though, provided that you eat a healthy, well-rounded diet. The benefits of increasing biotin intake for people with mild or no health problems are not well established (2).
To add insult to injury, biotin deficiency or excess can skew laboratory tests used to diagnose and treat a variety of medical conditions.
While it’s unlikely that you’d get too much biotin from food alone, the RDA is exceeded in many hair-, skin-, and nail-growth supplements.
The zinc, selenium, and other nutrients in eggs are beneficial to hair health. Because of this, they are among the best foods to eat for healthy hair.
