  1. I only get dips every few months for special occasions because I'm allergic to acrylates from a hybrid nail set gone wrong (at a professional salon). I think that's the best option overall. It can ruin your nail bed just as much as acrylics and gels would but in mine and my friend's experience it's not touching that allergic reaction territory as much. What do you think?

  2. Sometimes I do gel polish at home, but I have to soak for at least 45 minutes to remove them without scraping/filing the top layer of my nail off ☹️ I got my kit as a gift a long time ago and I don’t even know the brand, so maybe it’s time to invest in a new kit.

  3. I just had to do a double take the methylene chloride 😨
    There is a new lithium battery factory in Sweden, Eskilstuna who got permission to release tons of that stuff into the air…it's wild…
    Personally i'm just filing my gel nails 😀
    Gotta love products that were meant to be used in the shower with very fine screw neck caps… Loreal wonder water🤨I like the Redken version more anyway, LeaLuo Galaxy Paint
    I am here for the rant 😀
