Why Do My Nails Grow So Fast?

If you’ve ever wondered why your nails grow so fast, you’re not alone. The rate of nail growth varies from person to person, but on average, fingernails grow about 3.5 millimeters per month.

While toenails grow at a slightly slower rate of 1.6 millimeters per month. In this section, we’ll explore some of the factors that affect nail growth.


Your nails may grow faster or slower depending on the nutrients you consume. Nutrients like biotin, vitamin D, and iron are essential for growing healthy nails.

If you’re not getting enough of these nutrients in your diet, your nails may become brittle and prone to breakage.


Trauma to the nail bed can affect the rate of nail growth. If you injure your nail, it may take longer to grow back.

On the other hand, if you frequently use your hands for activities that put stress on your nails, like typing or playing an instrument, your nails may grow faster.


Hormones can also play a role in nail growth. For example, during pregnancy, some women experience faster nail growth due to increased circulation and hormonal changes.

Overall Health

Your overall health can also affect how fast your nails grow. People who smoke or have poor circulation may have slower nail growth. On the other hand, people who eat a healthy diet and exercise regularly may have faster nail growth.

Fingernails vs. Toenails

Fingernails and toenails grow at different rates and are generally subjected to different levels of trauma.

Toenails are generally subjected to less trauma than fingernails, which may explain why they grow at a slower rate.


Although it may sound like there’s no rhyme or reason to nail growth, genetics can play a role. Some people simply have faster-growing nails than others.

Nail Problems

If you’re experiencing problems with your nails, like brittleness or slow growth, it may be a sign of a nutritional deficiency or another underlying condition.

Talk to your doctor if you’re concerned about the rate of your nail growth or if you’re experiencing other nail problems.

Factors That Affect Nail Growth

If you’re wondering why your nails are growing so fast, there are several factors that can influence the rate of growth. Here are some of the most common factors that affect nail growth:


Your nails need certain nutrients to grow healthy and strong.

A deficiency in any of these nutrients can cause your nails to become weak and brittle, which can slow down their growth rate. Some of the nutrients that are important for nail growth include:

  • Protein
  • Biotin
  • Iron
  • Zinc
  • Vitamin C

Make sure you’re getting enough of these nutrients in your diet to promote healthy nail growth.


Hormonal changes can also affect the rate of nail growth. For example, during pregnancy, many women notice that their nails grow faster than usual. Hormonal imbalances can also cause changes in nail growth rate.

Blood Flow and Circulation

Good blood flow and circulation are important for nail growth. If you have poor circulation, your nails may grow more slowly.

Massaging your fingers and toes can help improve circulation and promote nail growth.

Trauma to the nail bed can also affect the rate of nail growth. If you injure your nail bed, your nails may grow more slowly or develop abnormalities.

People who bite their nails or pick at their cuticles may experience slower nail growth or other nail problems.

Overall, there’s no rhyme or reason to why some people’s nails grow faster than others.

However, by paying attention to these factors, you may be able to speed up your nail growth rate and grow healthy nails.


Taking care of your nails involves more than just filing and painting them. Your diet plays an important role in keeping your nails healthy and strong.

Consuming the right nutrients can help promote nail growth and prevent nail problems.

Vitamins and Minerals

Vitamins and minerals are essential for nail health. Here are some of the key nutrients that can help keep your nails strong and healthy:

  • Biotin: This B-vitamin is essential for nail growth and can help prevent brittle nails.
  • Vitamin C: This antioxidant vitamin helps promote collagen production, which is essential for nail growth.
  • Iron: Iron deficiency can cause brittle nails and slow nail growth.
  • Zinc: This mineral is essential for nail health and can help prevent white spots on the nails.
  • Calcium: Calcium is important for nail strength and can help prevent nail breakage.

Nails are made up of a protein called keratin, so it’s important to consume enough protein in your diet.

Here are some protein-rich foods that can help promote nail growth:

  • Lean meats, such as chicken and turkey
  • Fish, such as salmon and tuna
  • Eggs
  • Nuts and seeds, such as almonds and sunflower seeds
  • Legumes, such as lentils and chickpeas

Incorporating these nutrients into your diet can help promote healthy nail growth and prevent nail problems.

Remember to eat a balanced diet and consult a healthcare professional if you suspect a nutrient deficiency.


Your hormones have a significant impact on the growth rate of your nails.

Hormones are chemical messengers that regulate various bodily functions, including nail growth.

These hormones are produced by various glands in your body, including the thyroid gland, pituitary gland, and adrenal gland.

Thyroid hormones, particularly thyroxine and triiodothyronine, play a key role in nail growth.

These hormones regulate the metabolic rate of your body, which affects the speed at which your nails grow.

If you have an overactive thyroid gland, your nail growth may accelerate, while an underactive thyroid gland may slow down nail growth.

Estrogen and progesterone, the female sex hormones, also influence nail growth.

During pregnancy, when estrogen and progesterone levels are high, you may notice that your nails grow faster and become stronger.

During menopause, when estrogen levels decrease, your nails may become weaker and grow slower.

Cortisol, the stress hormone, can also affect nail growth. If you are under chronic stress, your cortisol levels may remain high, which can inhibit nail growth.

Blood Flow and Circulation

One of the factors that can contribute to fast nail growth is good blood flow and circulation.

When you have healthy blood flow, your nails receive the necessary nutrients and oxygen to grow quickly.

Your blood carries important nutrients and minerals that are essential for nail growth. These include vitamins like biotin, iron, and zinc.

When your blood is circulating well, these nutrients can reach your nails more easily, which can help them grow faster and stronger.

Poor circulation, on the other hand, can lead to slower nail growth. When your blood isn’t flowing as well as it should, your nails may not be getting the nutrients they need to grow quickly.

This can also lead to weaker nails that are more prone to breakage.

There are several things you can do to improve your blood flow and circulation, which can help promote faster nail growth. These include:

  • Getting regular exercise: Exercise can help improve your circulation by getting your blood pumping more effectively throughout your body.
  • Eating a healthy diet: Eating foods that are rich in vitamins and minerals can help ensure that your blood is carrying the necessary nutrients to your nails.
  • Staying hydrated: Drinking plenty of water can help keep your blood flowing smoothly and improve circulation.
  • Avoiding smoking: Smoking can constrict your blood vessels and lead to poor circulation, which can negatively impact nail growth.


Trauma to your nails can cause them to grow faster than usual. Trauma can include hitting your nail against a hard surface, getting your nail caught in a door, or even biting your nails.

When trauma occurs, it can stimulate blood flow to the nail bed, which can lead to faster nail growth.

This is because the nail bed is responsible for producing new nail cells, and increased blood flow means more resources for cell production.

However, trauma can also damage the nail bed and cuticle, which can lead to other nail problems such as ridges, discoloration, and even infection. It’s important to take care of your nails and avoid trauma as much as possible.

If you do experience trauma to your nails, you can try the following tips to promote healthy nail growth:

  • Keep the affected nail clean and dry to prevent infection.
  • Apply a moisturizing cuticle oil to the nail and cuticle to promote healing.
  • Avoid biting or picking at the affected nail to prevent further damage.
  • Consider taking biotin supplements to support healthy nail growth.

Do Fingernails Grow Faster than Toenails?

Fingernails do tend to grow faster than toenails, although the rate of growth is fairly slow. On average, fingernails grow about 3 millimeters per month and toenails grow less than 1 millimeter per month.

It’s not just that they’re growing at different speeds but also that our fingernails are exposed much more in everyday life which makes them thicker.

This extra exposure adds an additional layer of protection from trauma and abrasion while we tackle various day-to-day tasks.

The environment around our hands may also be a factor as they often come into contact with detergents, soaps and other cleansing agents that can affect the speed of growth.

Another thing to think about is the oxygen levels; finger nails receive more oxygen because our hands are almost always out in the open compared to feet which remain covered most of the time, thus providing a better environment for nail growth on the fingers than on toes. 


It is normal for nails to grow faster or slower than other people’s. Factors such as nutrition, trauma, hormones, overall health, and genetics can all influence nail growth.

Eating a balanced diet and getting enough of the key nutrients (such as biotin, iron, zinc and vitamin C) can help keep your nails healthy and promote faster nail growth. A

Having good blood flow and circulation can help get essential nutrients to your nails more effectively.

Fingernails tend to grow faster than toenails because they are exposed more in everyday life and receive more oxygen due to their location on the hands.
