Here are 10 foods that promote keratin production .

1. Eggs

Eating eggs is a great way to naturally boost keratin production .

In fact, they are an excellent source of biotin, an essential nutrient involved in the synthesis of keratin . only one egg cooked provides 10 mcg of this nutrient, or 33% of the Daily Value (DV) .

Plus, egg protein promotes keratin production , with 6 grams of protein packed into a large 50-gram egg .

Other healthy nutrients in this ubiquitous food include selenium , riboflavin and vitamins A and B12 .

Test-tube and animal studies further suggest that this popular allium vegetable may promote wound healing, fight microbial infections, and slow the signs of aging .

Garlic contains also many beneficial micronutrients, including manganese, vitamin B6, and vitamin C.
