However, few studies have conclusively proven whether or not calcium improves nail health. People at risk of calcium deficiency should consider supplementing their diet with this essential mineral. Calcium supplements that contain vitamin D are preferable. Nails are made of protein, and because of this, some people think that consuming too little protein in the diet adversely affects nail health. The authors of a study believe that there is a link between nail health and certain amino acids called collagen peptides that some proteins contain.
To increase the amount of protein in the diet, choose eggs, chicken or turkey , lean beef and pork, and fish. Vegetarian and vegan sources of protein include lentils, peanuts, nuts, and dairy products, such as cheese and milk. Biotin is a B-complex vitamin that might promote healthy hair and nail growth.
It might also strengthen brittle nails and prevent them from breaking, but there is little evidence that biotin supplements will help nails grow faster. When looking to improve the health and appearance of the nails, it is best to focus on limiting damage rather than expecting faster growth.
A well-balanced diet will make the skin and nails strong. Nail tissue is already dead by the time it is long enough to paint, so painting will not affect growth. It is also a myth that applying vitamins directly to the nails can help them grow.
These remedies are unlikely to help. At best, they strengthen the nail and prevent it from breaking. No specific nail polish, such as a gel or powder, can improve nail health.
In fact, some products, particularly those that require harsh methods for removal, may have adverse effects on nail health. The acetone that people use to remove gel nails can weaken nails despite the gel polish making them appear strong and healthy. Biotin has many other health benefits aside from improving the nails.
Learn more about them here. The hard part of the nail is called the nail plate. The nail plate, much like hair, is made primarily from a protein called keratin. The nail plate does not consist of living tissue, so it is not possible to improve the health of the nail plate.
While it is possible to prevent breakage there, the key to good nail health begins in the nail bed. The nail bed is the tissue underneath the nail. If the nail breaks off below the fingertip, it may expose the nail bed. Our Blog. What are Fingernails, Really? Can You Completely Lose a Fingernail?

Schedule an Appointment. You've had nails for a long time. In fact, you started growing nails before you were even born! Here are the different parts of your nails and how they grow:. The matrix : Each nail begins growing out of a little pocket under your skin. This is the root of the nail, and it's called the matrix.
The matrix constantly makes new cells. These new cells force the old ones to get packed together and pushed up through the skin. By the time the nail pokes out of the skin where you can see it , those cells are dead. That's why it doesn't hurt to cut your nails.
