How can I strengthen my nails?
I am 68 and healthy. I eat well and exercise regularly. Despite having thick hair and good teeth and skin, my nails have always been very weak. They can be soft but in brittle layers at the same time and rarely reach any length. My mother had the same problem, yet my two sisters have strong nails. Do you have any solutions? D.G.C.
You say you eat well, but it would be worth analysing your diet more closely. Check for iron deficiency and make sure you eat adequate protein. Underactive thyroid is another possibility. Frequent use of nail polish can weaken your nails. Wear gloves to protect hands and moisturise them daily.
