The structure of your nails is primarily made up of keratin, a protein also found in your skin and hair. This essential protein provides strength and resilience. However, certain factors can interfere with keratin production or weaken its structure, leading to brittle nails. But don't worry—there’s a solution. The key to healthy nails lies in the proper care you provide. Our nails deserve care too!!
