Regular use of biotin can strengthen your nails and make them less likely to split or break. There is no current safe daily limit for how much biotin you can take. You should still avoid taking large doses unless you're under the supervision of a doctor. Biotin is another name for vitamin B7. Incorporate foods into your diet that are high in this vitamin, which may boost the effect of your biotin supplements and make your nails stronger. Include any of the following choices: Barley Corn Egg yolks Milk Soy Avocado Broccoli Cheese Fish, chicken, and pork Expose your nails to water only when absolutely necessary, such as when you are showering or washing your hands. Wear gloves when you're washing dishes, doing chores, or exposing your hands to other liquids. Limiting your nails' exposure to water can keep them moisturized and minimize the risk that they break. Limit how much you expose your nails to household cleaners and detergents. Use a non-acetone nail polish remover to get rid of old polish. Harsh cleansers and chemicals can dry out your nails and protect your hands from strong detergents and other chemicals as you go about your day. Wear rubber gloves when you're washing the dishes or cleaning. People who live in areas with mild winters and hot summers have faster-growing nails. Take more vacations in warmer locales such as Florida, the Caribbean, Greece, or Bali if you're not ready to give up your life in the northern hemisphere for the sake of nail growth. Protect your hands when it's cold outside to keep your nails from getting brittle and give them the chance to grow long. Get plenty of sun, even in the winter, since the sun helps your body create the vitamin D your nails need to grow faster.
