By late August, I can usually tell exactly what kind of summer my hands have had without looking at a calendar. If I’ve spent weekends at the pool, washed produce constantly, gardened on my balcony, and forgotten gloves while cleaning, my nails give me away: vertical lines look deeper, the tips start peeling in paper-thin layers, and the whole nail plate feels dry enough to snag on a cotton towel. The good news is that this kind of damage is often less about “bad nails” and more about a badly dehydrated nail barrier that needs consistent, targeted care.
