Do your fingernails feel so brittle that the tips just snap off at the slightest knock? Do they split, crumble, and flake off into peeling layers? You are not alone. According to Dermatology and Therapy Journal, brittle nails are a common problem that affects up to 20% of the population, especially women older than 50.
The possible brittle nails causes can vary. Your nails can simply be too dry, you may have used too many chemicals, or you have a hormonal imbalance. But, there are other causes that you may not be familiar with, such as poor nutrition and fungal infections. This guide can help you recognize the causes and find adequate treatment for this condition.
What Are Brittle Nails?
Brittle nails are often hard nails that tend to snap off or break at the ridges. The brittleness of the nails means that your nails can easily become split, chipped, cracked, or peeled. The nails change as we grow older. They become dull and brittle.
But, before you can understand the brittle nails causes, you should recognize the two forms of brittle nails. You can either have “hard and brittle nails”, which means the nail doesn’t have enough moisture, or “soft and brittle”, meaning there is too much moisture.
What Are the Signs of Vitamin Deficiency in Nails?
“Why are my nails so brittle?” This is a common question at any nail salon. However, not many people realize that the nails can become brittle when there is a dietary deficiency. The nail plate is made of a protein known as keratin.
When you supply the body with a diet teeming with protein, minerals, and vitamins, you can keep the nails in excellent shape. But, when there is a deficiency in something, like protein, iron, biotin, zinc, or vitamin C, you can have brittle nails.
The first signs of vitamin deficiency in nails are rough nail plates, fragile nails, and peeling. For example, a lack of biotin causes ridges on the surface of the nail, a deficiency in vitamin C may trigger hangnails, and a lack of zinc can cause white spots on your nails.
What Are the Classic Brittle Nails Causes?
Want to know what causes brittle nails? The treatment depends on finding the cause. There are plenty of different factors that can affect the quality of your nails. Here is a list of some of the potential causes.
Our nails change with age. The older you are, the more likely they are to become brittle and prone to cracking and peeling. Your nails might also turn yellow and lose their natural transparency.
Nails, especially on the toes, might become tough and dense. As you get older, dealing with ingrown toenails could become more frequent. You may also find the tips of your fingernails prone to breaking.
Additionally, you might notice long, parallel lines forming on both your toenails and fingernails. If you notice any changes in shape or structure that are bothering you, it’s better to get them checked out sooner rather than later.
2. Low Iron Levels
Wondering what causes split nails? Iron is crucial for creating hemoglobin, a protein responsible for transporting oxygen throughout your body. When you don't have enough iron, it makes it more difficult to deliver oxygen to the cells that help your nails and hair grow.
Iron is crucial for cellular development, including the cells accountable for creating nails. When there isn't enough iron available, the nail matrix's cell replication process may become slower and less effective. This can result in nails that are more prone to harm and fracture.
Hypothyroidism is one of the most well-known brittle nail causes. Keratin starts to build up in the nail plate and causes ridges. Or there can be a drop in blood flow and nutrition to your nails, resulting in brittle nails and reduced growth.
Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can affect the quality of your nails. When these hormones are imbalanced, it can disrupt the normal processes involved in nail development.
They affect blood circulation, which decreases the nourishment to the developing nail, and causes a change in keratin production. Evidence from studies suggests that thyroid disorders can affect the entire metabolism. Such as how the body absorbs and uses nutrients.
This is why some people with thyroid disorders might encounter shortages of essential minerals and vitamins. So, if you find yourself grappling with brittle nails, you might want to have your thyroid checked.
4. Fungal Infections
Are you asking yourself “Why are my nails so brittle”? After your nail gets infected, the fungus typically begins at the edge. It then progresses toward the cuticle. Eventually, the entire nail becomes infected. The affected area can turn yellow or white. The nail can also turn brittle.
5. Nail Care Habits
If you want to know how to strengthen nails, give them a break. Overexposure to nail polish remover, household cleaners, and detergents can weaken your nails. Regularly applying nail extensions and nail polish can also cause them to become dry.
Another common mistake is using your nails as a tool. For example, opening soda cans or other containers, and trying to remove labels, stickers, or other materials. Scraping and prying can damage the nails.
Damage to the nails, like regular picking or biting, can cause brittleness. These habits weaken the nail structure over time. They apply constant pressure and force the layers of the nail to become damaged or to separate.
To make matters worse, biting and chewing on the nails disrupts the natural growth and healing process. It hinders the nail’s ability to develop properly. Therefore, the nails become brittle and more likely to split and crack. So, no matter how hard you try to care for your nails, if you keep biting and picking them, it is very hard to maintain their resilience.
How to Strengthen Nails
Now that you know the most common brittle nail causes, it is time to give your nails their strength back. The tips below can help.
