It is also helpful in production of keratin which is the structural protein of your hair, skin, and nails. Adequate intake of biotin makes hair follicles stronger, increases their elasticity and breaks less as time passes by, which means long, healthy and thick hair.

Eggs: The Ultimate Hair-strengthening Food

Eggs are considered to be one of the richest sources of biotin and more so the yolk. One cooked egg may contain as much as 10 micrograms of biotin, and so it is the superstar in your daily meals.

However, that is not the only thing, the eggs are also rich in high-quality protein which is required by your hair as a building material and to provide it with strength. As every strand of hair consists mainly of a protein known as keratin, it becomes necessary to intake proteins on a regular basis to avoid thinning and breakage.

In addition, eggs are also a source of other nutrients that attract hair e.g. zinc, selenium, and vitamin D that combine to help in maintaining the health of the scalp and prevent loss of hair.

Tip: Take advantage of your eggs boiled, poached or scrambled. Do not consume raw egg whites because it has avidin, the substance that may block the absorption of biotin.
