If your fingernails are soft , brittle and crack easily, here's a way to reverse this problem. Great answer for those who like to use fingernails for picking instead of guitar picks.
Go to your local pharmacy and buy Decolorized Iodine. Also know as white iodine. Walmart has it in quantity at a reasonable price.
Use a Q-tip or small brush to apply white iodine to fingernails from nail beds to tips and under tip ends 2 to 3 times a day for a week then 3 times a week thereafter as needed for maintenance.
You should see positive results shortly. Worked for me.
