Applying Lotions
Toenails often become brittle when they are exposed repeatedly to wet conditions. If you often doing activities that make your feet wet often, such as swimming, then this might be the case. Try lotions that contain lanolin or alpha-hydroxy to strengthen them. Make sure to check the ingredient list for those elements, which are effective in rebuilding the strength of your toenails. At the same time, you should avoid exposing your nails to water and other related activities. This can keep them dry and prevent them from becoming brittle. [3]
