How to Increase Keratin


Keratin is the hard protein that makes up your hair, nails, and the outer layer of your skin. Increasing your keratin may help give more flexibility, strength, and shine to brittle nails or thin, lank hair.[1] A deficiency of keratin can result in hair loss, sagging skin and nail breakage. You can increase your keratin naturally by eating a diet rich in keratin and other nutrients. Avoid common keratin-busting habits to further increase your keratin, and try using products that contain or increase keratin.
