Have talked to 2 hairdressers who have each worked in their jobs in past 15 years. They have each developed (and they each work at different salons in different cities), over-sensitivity to hair sprays, chemicals, etc. due to overexposure in their jobs.

The last time I work mascara was 25 years ago (yea, 1/4 century ago). My eyes felt heavier and more exhausted. So since I have naturally black lashes, even if on short side, no point trying much harder.

Wearing nail polish -- same, 25 years ago. My fingers felt cooler than normal, to me when I wore nail polish.

So as long as fingernails are neatly shaped and clean, it's ok.

And I never knew that nail extensions were painful to remove, if you change your mind...someone told me a few wks. ago.
