Why are My Nails So Sharp? [Mystery Solved]

  • Improper nail cutting. 
  • Deficiency of several vitamins like vitamin B, vitamin D, or low calcium levels. 
  • Brittle nails might result in sharpness and cracking due to hormonal abnormalities and hypothyroidism. 
  • Sharpness and peeling of the nail can also happen through external damage. Such as using the nail as a tool or applying too much pressure. 

If you are worried about your sharp nail, don’t worry. Read out the full article to know every possible reason why your nails are so sharp.

Key Takeaways

Reasons Why Your Nail Is So Sharp

Some of the vital reasons are:

  • Nutritional deficiencies
  • Hormonal imbalances
  • External damage
  • Inappropriate nail-cutting practices
  • Natural nail form

Deficiency of several vitamins like vitamin B, vitamin D, or low calcium levels are responsible for your thin and sharp nails. Overall peeling or weak nails can be caused by a general deficiency in iron, biotin, and vitamin C.

Viral warts, infections, and certain drugs can also lead to sharp nails, along with injuries to the fingers and hands. 

Nutritional inadequacies, such as zinc insufficiency, can also produce nail anomalies. Such as Beau’s lines, which are depressions that run across the fingernail. Also, dip nail cracking is a major cause of sharp nails.

How to Dull Your Sharp Fingernails

Now, as there are problems there are solutions. Here’s how you can fix your sharp fingernails.  

1. File your nails: Sharp edges can be rounded off with a regular nail file. By filing your nails, you may avoid damaging edges and maintain the health of your nails

2. Trim your nails straight across: Trim your nails straight across using manicure scissors or clippers, then gently curl the tips. Avoid too short nail cuts and rounded edges as they might make the nails grow sharper. 

3. Use moisturizer: Rub hand lotion into your fingernails, cuticles, and any exposed skin when using your hands. You may avoid sharpening and maintaining the health of your nails by doing this.

4. Apply a protective layer: Utilizing a nail hardener may assist to strengthen nails and reduce sharpness. Otherwise, there is a high chance of bending your nail by any external force.

5. Wear gloves: When cleaning, using strong chemicals, or washing dishes, put on cotton-lined rubber gloves. This can help keep the nails from becoming damaged and from getting too sharp.

6. Avoid biting your nails or picking at your cuticles: These practices increase sharpness and harm the nail. Even a little cut next to your fingernail can let germs or fungus in and lead to an illness.

7. Keep your nails clean and dry: By doing this, bacteria cannot develop under your fingernails. Split fingernails can be caused by prolonged or repeated contact with water.

Tips For Healthy Nails

Here are some recommendations from dermatologists for maintaining healthy nails:

  • Keep your nails always clean and dry.
  • Properly cut your nail by routine.
  • Utilize an emery board to shape and keep nails free of snags.
  • Avoid biting your nails or removing the cuticle.
  • Avoid using your nails as a tool, such as to open pop cans.
  • Regularly trim your toenails. It will reduce the possibility of trauma and harm if they are brief.
  • Put your feet in warm, salty water to soak when your toenails are thick and challenging to trim. For every pint of water, add one teaspoon of salt, and soak for five to ten minutes.
  • Avoid “digging out” ingrown toenails, particularly if they are infected and painful. Make an appointment with a dermatologist for treatment if you have an ingrown toenail.
  • Put on correctly fitting shoes. Wear different pairs of shoes every day as well.
  • When using public showers and the pool, wear flip-flops. This lowers the possibility of illnesses brought on by fungus that might grow in your toenails.
