I've been on an extended break from the salon for going on two whole years now. After years of bi-weekly gel manicures and a slew of too-harsh removals, my once long and strong nails were left in tatters: brittle and peeling; they were wholly incapable of growing.
While gel manicures shouldn't harm your nails, and any nail tech worth their salt will be gentle with removal, it was sadly too late for me, and I've spent the last few years trying to repair the damage. Part of that includes getting polish manicures and making sure the technician pays special attention to my cuticles.
