Understanding Ugly Toenails
Ugly toenails can be an embarrassing and frustrating issue. From discolored nails to thickened nails to fungal infections, unsightly toenails are rather common.
In this comprehensive guide, we will cover the major causes of ugly toenails, provide images to help identify issues, and give recommendations for managing and improving the appearance of unhealthy nails.
What Causes Ugly Toenails?
There are a variety of underlying reasons why someone may develop unattractive toenails, including:
- Fungal infections
- Injuries and trauma
- Nail disorders
- Poor hygiene
- Medical conditions
- Genetics
- Aging
Fungal Infections
One of the most common causes of ugly toenails is a fungal infection.Toenail fungus, known medically as onychomycosis, accounts for around 50% of nail disorders. Fungus thrives in the warm, moist environment inside shoes and spreads easily in communal areas like swimming pools, locker rooms, and showers.
Here are some key signs of a fungal toenail infection:
- Thickened, brittle, or ragged nail
- Deformed nail shape
- Dull, discolored nail
- Detached nail from nail bed
- Debris accumulating under nail
- White spots or streaks on surface of nail
Trauma and Injuries
Injuries to the toenail or toenail bed can often result in ugly toenail appearance. Common causes include:
- Improperly trimmed nails
- Dropped objects crushing nail
- Stubbed toes
- Ill-fitting shoes causing pressure and damage
- Pedicures that cut skin or remove too much nail
Signs that trauma is leading to unattractive nails include:
- Bruised nails
- Blood collecting under nail
- Nail plate separation
Nail Disorders
There are also genetic and autoimmune nail disorders that can cause ugly toenail presentation such as:
- Psoriasis
- Lichen planus
- Eczema
With these conditions nails often become:
- Loose and detached
- Pitted, grooved or ridged
- Discolored - black, brown, yellow
- Irregular shape
Poor Hygiene
Lack of proper nail and foot hygiene can also contribute to unattractive toenails over time due to buildup of bacteria, perspiration residue, dead skin cells and more. Key hygiene issues include:
- Not washing feet daily
- Forgetting to scrub under and around nails
- Wearing shoes without socks/stockings
- Not properly drying feet after bathing
- Sharing pedicure instruments
Medical Conditions
Certain underlying medical conditions are also associated with nail discoloration, thickening, detachment and other aesthetic issues such as:
- Diabetes
- Kidney disease
- Liver disease
- Heart disease
- Hypothyroidism
- Anemia
Consult a doctor if ugly nails arise without any other plausible cause as it may indicate an undiagnosed health problem.
Genetics
Some people are simply prone to thicker, more discolored nails due to genetics. Often many members within the same family experience similar nail issues despite no other contributing factors.
Aging
As we age, nails become more brittle and discolored. Older individuals often experience ugly toenails as the nails lose moisture and elasticity over time.

Treatment for Ugly Toenails
Treatment plans for unsightly nails vary depending on underlying cause. Here we will overview both at-home remedies and medical intervention options.
Improving Toenail Appearance
For fungal infections, injuries, poorly maintained nails and hereditary causes, you can improve ugly toenail appearance by:
- Trimming nails straight across to avoid ingrown toenails
- Filing nails to remove roughness and uneven edges
- Cleansing carefully under nails daily with a brush and soap
- Applying a topical nail hardening or strengthening treatment
- Soaking nails in Listerine, vinegar or essential oils
- Trying an over-the-counter liquid antifungal color polish
Medical Treatments
See a podiatrist promptly if at-home care fails to improve ugly toenails caused by:
- Untreated fungal infections
- Ingrown toenails
- Repeated nail injuries
- Underlying illness
A foot doctor can provide treatments such as:
- Oral or intravenous medications
- Medicated nail lacquers
- Nail and nail bed debridement
- Partial nail removal
- Laser therapy
- Nail matrix phenolization
These treatments are often 80% to 90% effective at resolving ugly fungal and damaged toenails.
When to See a Doctor
Schedule an appointment with your family doctor, dermatologist or podiatrist right away if you experience any of the following:
- Toenail fungus persisting longer than 3 months
- Rapid worsening of nail appearance
- Nail detached 50% or more from nail bed
- Presence of oozing, foul smell or intense pain
- Nail issues combined with unusual skin lesions
- Nail changes along with foot ulcers or infected skin
- No health conditions that explain ugly nails
These scenarios often require a medical professional to analyze underlying cause, check for complications like infection or skin cancer, and create a tailored treatment plan to restore healthy nails.
Prevention
You can help avoid many ugly toenail issues by focusing on good foot health habits:
- Disinfect pedicure equipment or use your own
- Wear shower shoes in public areas
- Alternate shoes daily to allow drying
- Select well-fitted footwear
- Treat athlete’s foot promptly
- Moisturize nails and cuticles
- Protect toes from injury with padded socks
- See a doctor at first sign of infection
Consistent prevention helps minimize risk factors and keep toenails looking healthy.
When to Seek Medical Care
See your doctor promptly if at-home care fails to improve ugly toenail appearance within 2 to 4 weeks. Relying too long on self treatment for progressive fungal and nail bed infections can lead to complications like:
- Permanent nail damage or loss
- Cellulitis bacterial skin infection
- Foot pain impacting mobility
- Spread of infection to other nails or skin
The sooner you seek podiatry assessment and intervention, the better chance you have of restoring healthy, attractive nails with minimal treatment time.
