What are your thoughts on painting the inside of your nails?
I only do my toes with colored polish so painting the underneath part of the nail wouldn’t work for me. Plus, I have short fingernails and just use top coat on the tips of the nail. However, I do like the look of the nails when they are painted underneath and agree with the other answers here. Just be careful you don’t paint underneath the nail where the finger and nail bed meet for risk of infection.
I’ve tried a yellow on top, blue on the underside and people loved it. I like to talk with my hands so when I sat in with a coordinator for one of my university’s programs, she stopped me in the middle of our conversation because she thought she was hallucinating and my nail color was changing.
It looks cool if you do black on top and red underneath the nail but it’s not practical unfortunately and only looks good in the photos. But not practical as it doesn’t last long.
