- A few months ago you wrote about horizontal lines and ridges on the nails and what causes the problem. I have forgotten the answer and a friend now has horizontal lines/ridges which are so bad that her toe nails have actually fallen off. Jacqui *
Your nails need building blocks to grow such as the nutrients selenium, calcium and zinc. They also rely on good circulation to support a healthy root bed. There are many ailments which reveal themselves in the poor health of nails. Waves or ridges appearing across the nail are often a sign of nutrient deficiency. In extreme cases, if the nail is of such poor health it will flake or break off. Marks such as white spots are bruises which have formed at the root of the nail and will grow out. One or two of these is OK as we all knock our hands now and again, but if you see them over both hands, it could indicate that your body needs more zinc and selenium. Nails with little holes may indicate the skin condition psoriasis, while scalloped nails can indicate poor circulation. Please remember that this is not a definite science and not all marks or shapings can always be tied to a health issue. Many times there is no rhyme or reason for the poor nail health with some people reading too much into the link between nail health and your overall health.
