Nail growth is influenced by a variety of factors, including genetics, nutrition, blood circulation, hormones, overall health, age, exposure to injury or trauma, and the environment. The rate of nail growth can also be impacted by the finger on which the nail is located, with the nails on the dominant hand typically growing faster due to increased use. Additionally, certain medical conditions, such as malnutrition and thyroid disease, can slow down nail growth. While it is an urban legend that fast nail growth indicates good health, changes in nail growth can sometimes be indicative of underlying health issues. For example, stress, high fever, serious injury, or infection can cause nails to stop growing temporarily as the body prioritises energy away from nail growth.

What You'll Learn
The rate of nail growth is largely genetically determined
Nail growth can also be affected by stress in the body. For instance, if you have a high fever, a serious injury or infection, or another severe illness, your nails may stop growing for a while. This is because your body shifts its energy away from non-essential tasks like nail growth to focus on recovery. When your nails start growing again, you may notice horizontal lines across them.

Certain medical conditions can slow down nail growth
While genetics and age are the main factors that determine nail growth, certain medical conditions can slow it down. Malnutrition and thyroid disease are two examples of conditions that can cause slower nail growth. In addition, if you have a high fever, a serious injury or infection, or another severe illness, your nails may stop growing for a while. This is because your body shifts its energy away from the low priority of growing nails to focus on recovery.

Nails on your dominant hand grow faster
It is an urban legend that fast-growing nails are a sign of good health. In fact, the speed at which your nails grow is largely determined by genetics, and a person in good health will grow nails at the speed that is typical for them. However, certain medical conditions, such as malnutrition and thyroid disease, can slow down nail growth. Nail growth is fastest at about age 10, then slows down a bit over a person's lifetime.
The nails on your dominant hand are said to grow faster simply because you use that hand more. This increases your risk of trauma, such as catching your nail on something or hitting it with a hammer. If trauma does occur, your body naturally sends more blood and nutrients to the area to help repair it, and this influx of nutrients may speed up nail growth. The rate of growth also depends on which finger the nail is on; a 2007 study found that the fingernail on your little finger grows slower than other fingernails.
Age can also impact nail growth, with younger individuals typically experiencing faster nail growth compared to older adults. Ultimately, a combination of genetic factors and overall health contributes to the rate at which your nails grow. Other factors that influence nail growth include nutrition, blood circulation, hormones, exposure to injury or trauma, and the environment.
In some cases, a change in your nails may be caused by stress in your body. For example, if you have a high fever, a serious injury or infection, or another severe illness, your nails may stop growing for a while. That's because, due to the extra demands placed on it, your body shifts energy away from the low-priority task of growing nails. When your nails start growing again, you may notice horizontal lines across your nails.

Pregnancy may speed up nail growth temporarily. A supplement, biotin, which is a B-type vitamin, does increase nail strength and growth rate in people with brittle nails, but its effects vary from person to person.

Nutrition, blood circulation, hormones, and the environment can also influence nail growth
Nail growth is influenced by a combination of factors, including nutrition, blood circulation, hormones, and the environment.
Nutrition plays a crucial role in nail growth. A well-balanced diet rich in essential nutrients can promote healthy nail growth. For example, a deficiency in biotin, a B-type vitamin, can lead to brittle nails, while adequate intake may increase nail strength and growth rate.
Blood circulation is also important. When trauma occurs to the nail, the body naturally sends more blood and nutrients to the area to aid in repair. This increased blood flow and nutrient delivery can accelerate nail growth.
Hormones can impact nail growth as well. For instance, during pregnancy, there may be a temporary increase in nail growth. Additionally, thyroid disease, which affects hormone production, can slow down nail growth.
The environment can also play a role in nail growth. Exposure to certain chemicals or physical trauma, such as catching your nail on a snag, can influence the rate of growth. Additionally, the natural ageing process contributes to nail growth, with younger individuals typically experiencing faster nail growth compared to older adults.
While genetics is a primary factor in determining nail growth speed, these external factors can also influence the health and growth of your nails.

Frequently asked questions
Nail growth is largely determined by genetics, but a person in good health will grow nails at a faster rate. Certain medical conditions, such as malnutrition and thyroid disease, can slow down nail growth.
This is common in people who bite their nails, as there is not enough nail to adhere to. It is the job of a nail technician to recognise and correct this.
Nails can develop white lines or spots as a result of injury, but these grow out with the nail and do not cause problems.
