Hair splinters occur when a strand of hair pierces the top layer of your skin, often affecting those who handle hair regularly. This can be painful and, if infected, may require antibiotics. Although rare, hair can also become embedded under nails, which can be removed through a variety of methods. In some cases, a strand of hair can affect nail growth, as seen in the rare case of a woman whose hair follicles produced human nails.

|---|---|
| Hair splinter | A rare condition that happens when a strand of hair pierces the top layer of your skin, particularly in hairless areas like the skin between your fingers. |
| Treatment | For hair splinters close to the surface, use duct tape to remove it. For deeper splinters, use a sterilized needle and tweezers to remove the hair, then rinse the area with warm water, apply an antibiotic ointment, and cover with a bandage. |
| Prevention | If you regularly come into contact with hair, take precautions to reduce your risk of hair splinters, such as wearing gloves. |
| Nail matrix | The nail matrix is responsible for producing new cells that form your fingernails and toenails. It consists of the germinal matrix (90%) and the sterile matrix (10%). |
| Nail injuries | Minor damage to the nail matrix can change the appearance of your nails. Severe injuries can cause the nail to fall off, and in some cases, it may not grow back. |
| Hyponychium | The hyponychium is the skin just under the free edge of your nail, acting as a barrier from germs and debris. It can sometimes overgrow, causing pain and increasing the risk of infection. |
| Unusual cases | In rare cases, an individual may experience a condition where their hair follicles produce human nails instead of hair, leading to black scabs and nail growth all over the body. |

What You'll Learn
Hair splinters can be painful and infected
A hair splinter occurs when a strand of hair pierces the skin and embeds itself under it. While hair splinters may sound like a minor injury, they can be very painful and irritating, especially if they become infected. Hair splinters are usually caused by freshly cut hair, which tends to be sharp and can easily penetrate the skin, especially if it is short, coarse, or thick. Those who handle a lot of hair, such as hairdressers, are at a higher risk of developing hair splinters.
Hair splinters can lead to infections if not treated properly. It is important to remove hair splinters as soon as possible to prevent infection. If the area becomes contaminated with dirt or bacteria, or if the splinter is not removed promptly, infection may occur. Signs of infection include increased redness, swelling, warmth, tenderness, and the presence of pus. If the infection spreads or causes inflammation in nearby tissues, it may result in difficulty moving or using the affected area, indicating that the infection is becoming more severe and requires medical intervention.
To prevent infection, it is recommended to apply a small amount of antibiotic ointment to the affected area and cover it with a bandage after removing the hair splinter. Additionally, keeping the area clean and washing your hands before attempting to remove the hair splinter can help reduce the risk of infection.
In some rare cases, hair splinters can cause a condition called creeping eruption, where the hair moves through the skin, creating a dark line. This condition is often confused with cutaneous larva migrans, a parasitic skin infection. If this occurs, a doctor may need to make a small incision to remove the hair properly.
While hair splinters can be painful and infected, they can usually be treated at home by removing the hair and applying antibiotic ointment. However, if there are signs of infection or difficulty removing the hair splinter, it is important to consult a healthcare professional for proper treatment and care.

A hair splinter may require antibiotics
A hair splinter occurs when a strand of hair embeds itself under the skin. This can be very painful and lead to infection. Hair splinters are typically caused by loose hairs becoming trapped in fabrics such as clothing, bedding, or carpeting, and piercing the skin upon contact or friction. They are more common in people with coarse or curly hair but can affect anyone.
Hair splinters can be treated at home in most cases. To remove a hair splinter, you can soak the affected area in warm water for a few minutes to soften the skin and hair, which may help loosen the splinter. After removing the splinter, thoroughly clean the area with soap and water to eliminate any remaining debris or bacteria. You can then apply a mild antiseptic or antibiotic ointment to prevent infection and promote healing.
However, if the hair splinter is deeply embedded or difficult to remove, or if you experience signs of infection, it is important to seek medical attention. Signs of infection include increased redness, swelling, warmth, or pus around the affected area. If the infection spreads or causes inflammation in nearby tissues, you may experience difficulty moving or using the affected area, indicating a more severe infection that requires medical intervention. Antibiotics may be prescribed by a doctor if they are deemed necessary to treat the infection.
In rare cases, if a hair splinter turns into an interdigital pilonidal sinus, a doctor will likely prescribe antibiotics as part of the treatment.

Fingernails are formed in the nail matrix
The nail matrix is where your fingernails and toenails form. It is made of special cells that constantly produce new keratin, which gathers at the nail plate and slowly pushes the nail forward, causing it to grow. Each nail matrix produces 196 layers of cells that combine to make each of your fingernails and toenails.
The nail matrix has two parts: the germinal matrix and the sterile matrix. About 90% of nail growth comes from the germinal matrix, while the remaining 10% comes from the sterile matrix, which is also responsible for keeping the nail attached to the underlying skin. The lunula, the white crescent shape at the base of your nail, is the only visible part of the nail matrix. The rest of it lies underneath your nail and is not visible.
Injuries and certain health conditions can damage your nail matrix and interfere with nail growth. Minor damage can cause temporary changes in the appearance and feel of your nail. Severe damage could cause your nail to fall off, and in cases of very severe damage, the nail may not grow back. However, in many cases, the nail matrix will heal with proper care, and the nail will start to grow again after several weeks.
Some factors that can affect the nail matrix include fungal infections, certain illnesses, and injuries such as pinching or crushing your finger. Medications, peripheral artery disease, and skin conditions like eczema can also impact the nail matrix, causing Beau's lines (horizontal ridges), slow nail growth, and other changes in texture or colour.

A severe injury can cause your nail to fall off
If your nail falls off due to an injury, it will usually grow back with proper medical care. The nail matrix, located under the base of the nail, is responsible for nail growth. In most cases, the nail matrix will heal, and a new nail will begin to grow within a few weeks. However, severe damage to the nail matrix can result in permanent nail loss.
It is important to seek medical attention for severe nail injuries. Before seeing a doctor, there are several steps you can take to care for the injury. Remove any jewellery from the injured finger, as swelling can make it difficult to remove later. Gently wash the injury, especially if it is bleeding, and apply a bandage if necessary. If the injury is minor, such as a small subungual hematoma, you may be able to treat it at home by draining the trapped blood. This can be done by heating a needle or paper clip, sterilizing it with rubbing alcohol, and gently penetrating the nail to create a small hole for the blood to drain. However, it is important to note that this procedure should be performed within 48 hours of the injury, before the blood clots.
For more severe injuries, such as a deep cut to the nail bed or a finger fracture, it is recommended to see a doctor. They may take an X-ray to check for broken bones and provide treatment to relieve pain and promote proper nail growth. In some cases, surgery may be required to repair the nail bed and underlying tissue.
While nail injuries can be painful and unsightly, with proper care and treatment, most people can expect their nails to grow back healthy and strong.

A rare condition can cause hair to turn into black fingernails
A rare and mysterious condition has caused a woman's hair to turn into black fingernails, leaving doctors baffled. Shanyna A. Isom, a 28-year-old beautician and former law student, has been diagnosed with an unknown condition that has caused her body to produce nails instead of hair. Isom's condition first arose in 2009 when she suffered an allergic reaction to steroids prescribed for an asthma attack. She began itching uncontrollably, and soon her legs turned black with scabs.
Doctors at Johns Hopkins Medical Center in Baltimore determined that Isom was producing 12 times the normal number of skin cells in each hair follicle, resulting in the growth of nails instead of hair. The disease has affected not only her skin but also her bones and vision, leaving her unable to walk without a cane. Isom's mother, who cares for her at home, described the nails as "hard to touch and [they] stick you."
Isom's condition has resulted in $500,000 in unpaid medical bills, as her state insurance does not cover treatment in Maryland. While there is currently no cure, Isom has created a foundation to help cure other mystery illnesses.
In rare cases, hair can become embedded under the skin, a condition known as a hair splinter or barber's disease. This typically occurs when freshly cut hair penetrates hairless areas, such as the skin between the fingers. While hair splinters are usually mild, they can occasionally turn into something more serious, such as a creeping eruption, which causes a dark line under the skin.

Frequently asked questions
A hair splinter, sometimes called a hair sliver, happens when a strand of hair pierces through the top layer of your skin. This may sound like a minor injury, but hair splinters can be very painful, especially if they become infected.
Dissolve Epsom salt in warm water and soak your finger in it for 10 minutes. It should pull out the hair splinter at least partially, if not completely. Alternatively, you can try placing duct tape over the area and gently pulling it off.
In rare cases, yes. In 2012, a woman's hair follicles were found to be producing human nails instead of hair. Doctors think her skin wasn't getting enough oxygen, and she was lacking vitamins A, B, C, D, and K.
The skin under your nails, called the hyponychium, can overgrow and thicken due to a fungal nail infection, also known as onychomycosis.
If you are experiencing thick skin under your nails, consult a dermatologist to determine the best treatment.
