Weak nails typically become brittle, break and split easily, and may even grow more slowly than normal. Nails often become weaker and thinner with age, but external factors such as exposure to harsh chemicals or water can also cause the problem. In most cases, home remedies can help improve nail strength. Always consult a physician if your nails do not improve or the condition worsens, however, as this may indicate a nutritional deficiency.
Biotin
Biotin, a B-complex vitamin also known as vitamin H or vitamin B-7, may help increase nail thickness and strength. A study published in the scientific journal Cutis in 1993 found that 63 percent of patients given regular biotin supplementation experienced a significant increase in nail plate thickness. Although 34 percent of the patients reported no change, the study suggests that the vitamin may produce positive results in some individuals. In his book "Healing Without Medication" Robert Rister recommends taking 300 to 600mcg of biotin daily to strengthen weak nails. It may take up to six months to see results.
Olive Oil
A traditional home remedy for strengthening weak nails, olive oil also moisturizes the nails and nail bed. In the book "Natural Remedies: Non-drug Healing Strategies That Work Best," the Prevention Health Books' staff recommend immersing your fingertips in the oil daily to fortify weak nails. Warm a half cup of extra virgin olive oil over low heat for about five minutes, and soak your nails for 15 to 30 minutes daily for best results. Never allow the oil to come to a boil and test the temperature before using to prevent injury.
Horsetail
A medicinal herb often used in natural cosmetics for the nails and hair, horsetail may help strengthen weak nails. Jude C. Todd, author of "Jude's Herbal Home Remedies," suggests making your own nail strengthener by brewing a strong horsetail infusion and soaking your fingertips in the liquid. Steep 6 tbsp. dried horsetail stems in 2 1/2 cups boiling water in a stainless steel pan for about four hours. Place the pan over low heat after four hours and simmer for an additional 30 minutes. Remove from heat and allow the mixture to stand for 30 more minutes before straining. Soak your nails in the liquid every other day for 15 minutes. Make a new batch at least once a week.
Black Currant Seed Oil
Made from pressed black currant seeds, black currant seed oil may help strengthen weak, brittle nails. The oil is a natural source of gamma-linolenic acid, also known as GLA, that may be responsible for its strengthening effects on the hair and nails. On his website, Dr. Andrew Weil, M.D. recommends taking 500mg of black currant seed oil standardized to contain at least 45mg GLA twice daily. Children should take half this amount. Always consult a qualified medical professional before taking any nutritional or herbal supplement, especially if you take prescription drugs.
