Q. My fingernails have always been weak. I took Knox Gelatine years ago, and most recently I have taken biotin and gelatin capsules. My nails improved a little, but then I used nail polish for a month to show them off.
The nails have started splitting and peeling again. I’d be grateful for any suggestions.
A. Nail polish or remover often contains solvents that can weaken nails. Sometimes avoiding polish is an important step to stronger nails.
Moisturizing nails with Epilyt or almond oil can be helpful. Many readers have reported that taking the dietary supplement MSM (methylsulfonylmethane) strengthens nails.
