Egg protein and hair.

Egg whites are complete protein containing all the essential amino acids. You need protein in your diet to build, maintain, and replace the tissues in your body — including your hair.

Protein for healthy hair

The hair shaft has three layers:

• Medulla. This is the soft, inner layer of the hair shaft, only seen in large and thick hairs.
• Cortex. This middle layer of the hair shaft provides the hair’s strength, color, and texture.
• Cuticle. This is the thin, colorless outer layer of the hair shaft that protects the cortex.

Your hair shaft is largely keratin, a fibrous protein that is also the main structural component of your nails. When your diet includes the proper amount of protein, you’re giving your body what it needs to produce stronger, healthier hair.

The benefits include:

• a stronger cortex, which makes your hair less likely to form split ends and break
• a strengthened, smoother cuticle to make your hair shinier

Proper intakes of protein is critical to healthy hair.Research shows that women who don’t consume enough protein can experience hair thinning, fragility, and loss. Chemical treatments, heated styling techniques, and environmental oxidation also contribute to protein loss in your hair.
