Keratin is a protein that helps form hair, nails and your skin's outer layer (epidermis). If your body isn't able to make enough keratin because your diet is short in protein, key nutrients, etc... the effects will likely be noticeable in your hair, nails, and skin. Your hair and nails may grow at a slower rate, and become more brittle and less shiny and smooth. #keratin #dullhair #brittlenails #dryskin #skincare #nutrition #diet #health #healthy #skintok #fyp #foryoupage #for #you
