The Damage You See in September Is Sixty Small Ones Added Up: Manicurists Said What the Ads Skip

After three months of salt, chlorine and sun, nails break, peel and turn rough. The industry has an answer for that - an entire shelf of products. The two manicurists quoted in this story start somewhere else: at the cuticle.

"The first step towards healthy nails starts at the cuticle," says Natalia Gonzalez. Not at the polish, not at the serum, not at the most expensive ampoule. A cuticle that is dry and lifted leaves the nail plate unprotected at the point where it grows, and everything else follows from there.

Aude Peyrefiche, who runs the Spanish arm of a nail care brand, reduces the whole process to four words: clear, repair, feed, protect. That means - take off the polish, cut the nails short, apply a treatment, rub oil around the plate, and keep a protective base on for a few weeks. None of that requires a new product every month.

Her explanation of why nails suffer at the seaside is the interesting part. The problem is not one aggressive exposure but the cycles of wetting and drying repeated every single day. The plate swells, then contracts, for weeks on end. The damage you see in September is sixty small ones added up, not one big one.

Filing has its own rule and it is the one most often broken: always in the same direction, never back and forth. A zigzag motion creates micro-cracks you do not see until the nail breaks. The same logic applies to removing gel polish - when it is peeled off, the surface layers come with it, and the nail is left thin and sensitive.

Hydration is recommended daily, ideally in the evening: a drop on each nail, then massage the cuticle, the sides and the free edge. Thirty seconds. That is the whole routine the two women who work with nails professionally single out as the most important one.

The products exist and run from nine to thirty-four euros. But notice what the trade says and what the advert says. The trade says: cut them back, come back to them, wait. The advert says: buy something new. A nail grows at its own pace and that pace is not for sale.
