A detached toenail can result from an injury, fungal infection, or underlying skin condition such as psoriasis. If the nail is only partially detached, it is important to leave the remaining part in place to prevent further injury. Soaking the affected toe in cold water for 20 minutes can help ease any pain and swelling. Once the nail has softened, a clean pair of scissors or nail clippers can be used to carefully trim off the loose part. It is important to smooth any jagged or sharp edges with a nail file and to keep the nail bed protected with ointment and a bandage.

What You'll Learn

Soak your nail in warm water to soften it
Soaking your nail in warm water is a great way to soften it, especially if you want to remove glue-on fake nails. Start by preparing warm water—it shouldn't be too hot, as you'll be soaking your nails in it for a while. You can also add some soap to the water, as this will help the process by softening the glue.
Once you have your warm water (and soap, if you're using it), soak your nails in it for around 15 minutes. If you're removing fake nails, the warm water will help to soften the glue, making it easier to peel the nails off. You can use a nail file to gently pry the nails off, starting at a spot where the nail has already begun to detach. If the glue is still too hard, you can soak your nails for a little longer.
Soaking your nails in warm water can also be a good way to treat nail psoriasis. Your doctor may prescribe medicated creams to help with this, and you may also be advised to try phototherapy (light therapy).
If you have a loose toenail, soaking your toe in warm water can help to ease any pain and swelling. You can then trim off the loose part of the nail with clean scissors or nail clippers, snipping along the line of the tear to create an even edge. You should then protect the exposed nail bed for 7 to 10 days, keeping it clean and coating it with antibiotic ointment.

Clip off loose nails with nail clippers
If you have a loose nail, it is important to address the underlying cause, which could be an injury, fungal infection, or psoriasis. If you have any concerns, you should seek medical advice.
If your nail is loose due to onycholysis, you can use nail clippers to cut away the separated nail as it grows out. If you have a detached toenail, you should not pull off the remaining part of the nail. Instead, you should trim or file any jagged or uneven edges to smooth them out and prevent further injury.
To clip your nails, start by softening them. You can do this by soaking your nails in water for a few minutes. Then, use clean nail clippers to cut your nails straight across at the beginning of the opaque, overgrown tips. You may need to make multiple cuts on the same nail to get the whole tip off. Be careful not to cut past the opaque tips of your nails, as this could expose the sensitive skin underneath.
After clipping your nails, you should disinfect your nail clippers. Clean the clippers with soapy water, then spray them with a sanitizing spray. Alternatively, you can scrub your nail clippers with a small brush soaked in a bowl of 70 to 90 percent isopropyl alcohol. Finally, rinse the tools in hot water and dry them completely before putting them away.

Smooth sharp edges with a nail file
If your toenail is loose, you can soak it in warm water and gently remove the nail with clippers or scissors. If the nail has cracked from side to side without leaving a rough edge, you can skip the trimming. However, if there are jagged or uneven edges, you should smooth them out with a nail file to prevent further injury.
Choosing a Nail File
Nail files come in various grits, which refer to the size of each grain of sand on the file. The higher the number, the smoother the file grit, and the less material will be removed from your nail. For natural nails, it is recommended to use a soft-grit nail file with a grit of around 180-240. Emery board files are both affordable and effective. Avoid metal files, as they are more difficult to control. Glass or crystal files are also effective and can be easily cleaned in the dishwasher.
Filing Technique
Before filing, ensure your nails are totally dry to avoid making them prone to breakage or rough edges. Position your hands so that your fingers point toward you, which will help you see your work. File in single strokes along the grain of your nail, moving in a single direction from the edge toward the centre. For rounded or pointed shapes, start by filing the outside edges and work your way toward the centre to create a smooth and gradual curve. For squared nails, file perpendicular to the tip until flat, then smooth out the edges.

Treat fungal infections with antifungal medication
If you have a loose nail, it is important to address the underlying cause to prevent it from occurring again. One common cause of nail separation is a fungal infection. Fungi can grow between the nail and the nail bed, causing the nail to thicken and turn yellow, with white spots and streaks. If left untreated, the nail may fall off.
To treat a fungal nail infection, your healthcare provider may prescribe antifungal medication. Antifungals are antimicrobial medications that target fungal cell components, disrupting their growth and survival. They can either kill the fungus or prevent it from multiplying and growing. Antifungal medication can come in various forms, including:
- Oral medication: Your doctor may prescribe liquid medicines, pills, or tablets that you swallow with water. These medications may include terbinafine (Lamisil), itraconazole (Sporanox), and fluconazole (Diflucan).
- Topical medication: Topical medications come in the form of creams, ointments, gels, sprays, or powders that you apply directly to your nails. It is important to follow your healthcare provider's instructions and complete the full course of treatment to prevent the fungus from returning and becoming harder to treat.
In addition to antifungal medication, there are other steps you can take to treat and prevent fungal nail infections:
- Keep your nails dry and clean. Avoid keeping your nails in water for too long, as this can cause nail separation.
- Avoid chemicals and products that can irritate your nails or the skin around them, such as nail polish, nail gloss, nail hardeners, and nail polish remover.
- Wear gloves when doing activities that may damage your nails, such as washing dishes or gardening.
- Wear clean, comfortable socks and protective shoes that fit properly.
- Be careful when putting down heavy objects near your feet to avoid injuring your nails.
It is important to note that treating fungal nail infections can be challenging, and medication may need to be taken for months or even years. Side effects from antifungal medication may include abdominal pain, an upset stomach, diarrhoea, itchy skin, a burning sensation, or a skin rash. More severe side effects can include liver damage and severe allergic reactions. Always consult your healthcare provider to determine the most appropriate treatment option for you.

Avoid nail products that can irritate your nails
If you have a loose nail, it is important to address the underlying cause to prevent it from happening again. One common cause of nail separation is onycholysis, which can be triggered by an allergy to nail products.
To avoid nail products that can irritate your nails, it is important to understand the potential allergens and irritants present in these products. Nail cosmetics include nail enamels (varnish/polish), nail enamel removers, cuticle removers, and artificial nails. An allergy to any of these products can lead to nail diseases such as paronychia, onycholysis, and other nail dystrophies.
The most common chemical responsible for allergic reactions to nail enamel is tosylamide formaldehyde resin. However, some people may also react to the solvent butyl acetate or experience discolouration of the nail surface due to colourants. Nail varnish used as a barrier against nickel allergy can also cause sensitisation. The strong solvents used in nail enamel removers, such as acetone and alcohol, can further irritate the skin and nails.
Acrylic nails are another common source of skin irritation. The chemicals used to shape and harden acrylic nails, such as acrylates, can lead to contact dermatitis, causing redness, itching, and swelling. If you experience these symptoms, it is important to see a dermatologist and consider switching to hypoallergenic products, gel nails, or dip powders designed for sensitive skin.
Additionally, regular manicures can also contribute to onycholysis due to the force applied during trimming, buffing, and polishing. Therefore, it is advisable to allow your nails to recover and avoid excessive manicure treatments.
Overall, to prevent nail irritation and separation, it is crucial to identify any nail product allergies and avoid the specific allergens. This may involve opting for hypoallergenic alternatives or reducing the frequency of certain treatments.
