Nail Issues: What Happens When Hair Gets Stuck?

Nail problems

Hello doctor, a very short hair suddenly got stuck deep in the nail fold, and I can't seem to get it out.
I read online that hair can penetrate the skin and wander in the body.
If I don't remove that hair, will it move around in my body, or will my body automatically expel it? Currently, I don't feel any pain.
Thank you for your response.

It will not migrate, but it is still recommended to remove it.

More Info

When it comes to hair getting stuck under the nail or embedded in the skin, it can be a concerning situation, but it’s important to understand how the body reacts to foreign objects like hair.
Firstly, if a hair gets lodged under your nail, it typically does not "wander" through the body. Hair is made of keratin, a protein that is not harmful to the body. If the hair is stuck under the nail and you cannot remove it, the body will not allow it to move around or travel through the bloodstream or tissues. Instead, the hair will remain in place until it is either removed or the body naturally sheds it.

In most cases, if the hair is not causing any pain or discomfort, it may eventually work its way out on its own as your body continues to grow new nail tissue. The nail grows from the nail matrix, which is located under the cuticle, and as the nail grows, it may push the hair out. However, this process can take time, and the hair may remain trapped for a while.

If the hair is causing irritation or if you notice any signs of infection, such as redness, swelling, or pus, it is advisable to seek medical attention. A healthcare professional can safely remove the hair and assess any potential damage to the nail or surrounding skin.
In terms of self-care, if you are not experiencing any pain, you can keep the area clean and dry. Avoid trying to dig out the hair yourself, as this could lead to injury or infection. If you do decide to attempt removal, ensure that you use clean tools and take care not to damage the nail bed or surrounding skin.

In conclusion, while it may be unsettling to have a hair stuck under your nail, it is unlikely to cause significant harm. The body has mechanisms to deal with foreign objects, and in many cases, the hair will either be expelled naturally or can be safely removed by a healthcare professional if necessary. If you have any concerns or if symptoms develop, do not hesitate to consult with a doctor for further evaluation and treatment.
