Nail keratin debris is a fungal infection of the nail. In medical terms it is called an onychomycosis or tinea unguium. The common symptom of this condition is a dirty yellowish discolouration of the nail, which a manicure or pedicure cannot remove. If you notice that your nails are starting to discolour, you can prevent this from getting worse by using homemade remedies.
Pour warm water in the water basin. Pour enough water to allow you to soak your hand or feet completely. The water basin should be big enough to fit your hand or your foot, depending on what nails are infected with the fungus. Mix 3 bottle caps of apple cider vinegar with the warm water. Soak your affected hand or foot in the vinegar and water mixture for 20 minutes. Dry your hand or foot with the blow dryer afterwards. The blow dryer will make the mixture stick to the hand or the foot so that it will be able to help kill the fungus.
Put 1 to 2 drops of tea tree oil on the affected nails if you want to use the oil instead of the apple cider vinegar, since some do not like the smell of vinegar. Spread the tea tree oil over the nails evenly. Apply this 2 to 3 times a day for 3 weeks.
Mix 1 teaspoon of olive oil with 2 drops of oregano oil. Apply the mixture to the infected nails. The oregano is a good antiseptic as well as antifungal remedy. Apply this mixture daily for 3 to 4 weeks.
Cut nails short to prevent fungus or bacteria from housing behind the nails.
If the homemade remedies do not work after applying for the number of days indicated, consult a foot doctor.
