natural senility

[Itasan]

1-1. naturally curly hair - OK?
1-2. natural wave - OK?
1-3. natural permanent (wave) - NO?
2. natural senility
Just like myself, who forgot the most
important wedding reception and lots of others at the age of 40 or so.
If 2 doesn't work, is there any other word?
Thank you.
