Nails are made of the same protein, keratin, as our skin and hair and protect the soft tissue beneath them. Fingernails and toenails can be lost due to trauma, infection, or other reasons. Nails do grow back, but it may take several weeks or months. Fingernails may take up to six months to grow back, while toenails can take up to eighteen months. Nails grow back from the matrix, the root of the nail, and new cells push through the skin, eventually hardening into nails.

What You'll Learn
Nails will grow back, but slowly
Yes, nails will grow back, but the process is slow and can take several weeks or even months. The rate of regrowth depends on various factors, including age, health, and climate. Nails tend to grow slower in older adults and in colder climates, while trauma or injury can increase the rate of regrowth due to increased blood flow to the injured area. Overall health also plays a role, with nail growth slowing down if you're sick or malnourished.
The time it takes for a nail to grow back depends on whether it is a fingernail or a toenail. Fingernails may grow at a rate of about one-tenth of a millimeter each day, resulting in a complete regeneration within 4 to 6 months. Toenails, on the other hand, grow at a slower rate, taking up to 18 months to fully regrow.
The matrix, or root of the nail, is responsible for nail growth. The germinal matrix contributes about 90% of the nail growth, while the sterile matrix accounts for the remaining 10% and helps keep the nail attached to the underlying skin. Injuries, certain medications, and health conditions can damage the nail matrix and interfere with nail growth. In some cases of severe matrix damage, the nail may not grow back completely or at all.
It is important to keep the area clean and dry to prevent infection while waiting for the nail to grow back. Home treatments can help relieve pain, promote healing, and protect the sensitive skin underneath the nail. Trimming any sharp edges or covering the nail with tape or a bandage can prevent further tearing and protect the nail bed.
While it may take some time and patience, nails will usually grow back after being pulled off, with proper care taken to ensure the area remains clean and infection-free.

Fingernails grow back in 4-6 months
Fingernails can grow back in about 4 to 6 months. Nails have good regeneration capacity, but they grow slowly. Fingernails may grow about one-tenth of a millimeter each day, so completely removed fingernails usually grow within 6 months. Toenails, on the other hand, may grow at a slower rate, with complete regrowth taking up to 18 months.
Several factors can affect the speed of nail regrowth. For instance, nails tend to grow slower in older adults and in colder climates. Nails grow faster during the summer and on the dominant hand compared to the non-dominant hand. Additionally, trauma or injury can increase the rate of regrowth due to increased blood flow to the injured area. Overall health can also impact nail growth, with slower growth occurring when individuals are sick or malnourished. Hormones can also play a role, as nails may grow quicker during pregnancy.
It is important to keep the nail bed dry, clean, and covered with petroleum jelly and an adhesive bandage until the nail has regrown to promote healing and prevent infection. The area underneath the nail is very sensitive, and the risk of infection is high. Signs of infection include increasing heat, redness, pain, tenderness, swelling, or pus.
In some cases, surgical nail removal may be necessary due to severe nail fungus, recurrent ingrown toenails, or when a large section of the nail is diseased or damaged. Ingrown toenails can cause pain and discomfort, and if left untreated, can lead to infection, foot ulcers, and other serious problems. After medical removal, it can take up to 18 months for a nail to fully regrow.
While waiting for the nail to regrow, it is important to file any sharp edges smooth or trim the nail. Covering the nail with tape or an adhesive bandage can help protect the finger or toe until the nail has grown out enough.

Toenails take longer, up to 18 months
Toenails take significantly longer to grow back than fingernails. While fingernails can take anywhere from four to six months to grow back, toenails can take up to 18 months to fully regrow. This is because toenails grow at about half to a third of the rate of fingernails.
Several factors can affect the speed of nail regrowth. Nails tend to grow slower in older adults and in colder climates. For instance, nails grow faster in the summer. Nails on the dominant hand also tend to grow faster than nails on the non-dominant hand. Additionally, trauma or injury can increase the rate of regrowth due to increased blood flow to the injured area. Overall health also impacts nail growth. For example, nail growth can slow down if you're sick, malnourished, or have certain illnesses or conditions.
Peripheral artery disease (PAD), for instance, causes reduced blood flow to the legs and feet, which can slow nail growth. Skin conditions, such as severe eczema, can also affect the nail matrix and temporarily interfere with nail growth. Similarly, nail psoriasis can cause white lines, pitting, and crumbling of the nails. Certain medications can also cause temporary changes to the nails, such as Beau's lines (horizontal ridges) and slow nail growth.
In some cases, surgical removal of a nail may be necessary due to severe nail fungus, recurrent ingrown toenails, or when a large section of the nail is diseased or damaged. After medical removal, it can take up to 18 months for the nail to fully regrow. Ingrown toenails are a common issue that can cause pain and discomfort. In such cases, removing the toenail can be a relief and prevent further issues.

Nail matrix injuries can cause nails to fall off
The nail matrix is the "factory" where your body makes new fingernails and toenails. It is responsible for the growth of strong, healthy nails. The nail matrix creates new cells that become your fingernails or toenails. About 90% of nail growth comes from the germinal matrix, while the remaining 10% comes from the sterile matrix, which also keeps the nail attached to the underlying skin.
Injuries and certain health conditions can damage the nail matrix and interfere with nail growth. Mechanical injuries, such as pinching or crushing the finger or dropping something heavy on the toe, can injure the nail matrix. Sharp injuries, such as a strong blow or crushing with a heavy object, can also cause damage. In addition, wearing tight shoes can create micro-injuries that disrupt healthy nail growth, leading to a thinner nail plate, deeper grooves, and ridges. Nail matrix injuries can cause bruising, ridges, or discoloration, and in severe cases, the nail may fall off.
Certain habits and improperly performed nail care procedures can also damage the nail matrix. For example, cuticle picking can lead to a wavy nail plate, while improper use of a drill or cuticle cutting with a pusher can cause nail plate distortion and even matrix damage. Aggressively removing hybrid, acrylic, or gel manicures with overly sharp tools can also damage the nail matrix.
It is important to note that nail matrix damage can lead to serious problems, such as nail plate deformities, detachment of the nail from the matrix, or nail diseases. Treatment is available, and with proper medical care, nails usually grow back after falling off. However, in cases of severe nail matrix damage, some or all of the nail may not regrow.

Nail infections may require surgery
Nails have a good regeneration capacity and will grow back after being pulled out or falling off due to injury. However, this process can take time, with fingernails taking up to 6 months and toenails taking up to 18 months to fully regrow. During this time, it is important to take care of the affected area to ensure proper healing and avoid infection.
Nail infections, such as paronychia, can occur when bacteria or fungi enter broken skin near the cuticle and nail fold. This can lead to inflammation, pain, swelling, and pus buildup under the skin. While mild cases of paronychia can be treated at home with warm water soaks, more severe infections may require antibiotics or drainage of the abscess. In some cases, if the infection is severe and does not respond to other treatments, surgery may be necessary to remove the nail entirely and allow a healthy nail to grow back.
Fungal nail infections, such as candida or tinea, can also lead to nail dystrophy, with symptoms including nail discoloration, thickening, and crumbling. These infections thrive in dark, warm, and moist environments, making toenails particularly susceptible. While topical antifungal treatments can be effective for mild infections, more severe cases may require oral medication or surgical removal of the nail.
Subungual melanoma, a type of skin cancer that affects the nail matrix, can also require surgery to remove the affected area. Additionally, nail injuries, such as bruising under the nail, can be treated with a procedure called nail trephination, which provides pain relief and helps the new nail grow in correctly.
It is important to note that nail infections and injuries can have various causes and treatment options. If you suspect a nail infection or experience nail trauma, it is recommended to seek medical advice from a healthcare professional for proper diagnosis and treatment.
