Why Does the Free Edge of Nails Split?

You finally grow your nails to the perfect length… and then the tips start peeling. Sound familiar? In Dubai, this happens more often than many expect. Between air conditioning, hand sanitisers, swimming pools, and constant hand washing, nail tips go through a lot.

At It’s Beauty, we regularly see clients who say, “My nails grow, but the ends keep splitting.” Usually, the reason is simpler than it feels.

What Exactly Is the Free Edge?

The free edge is the part of the nail that extends past your fingertip. It looks small, but it carries most of the daily stress.

Unlike the base of the nail, this part has no support underneath. So when pressure, dryness, or friction build up, the layers can begin to separate. That’s when peeling starts.

Think of it like thin layers of paper lifting from the corner. Once it begins, it tends to continue unless the edge is protected.

Why Nail Tips Split

There are usually several reasons behind nail splitting. In most cases, it comes down to a mix of everyday habits and environmental factors.

Dry air and dehydration

Dubai’s climate plays a role. Heat outside, strong AC inside. Nails lose moisture quickly in this cycle.

When a nail becomes too dry, it loses flexibility. Instead of bending slightly under pressure, it cracks.

Frequent sanitiser use adds to this. It evaporates fast and takes moisture with it.

Constant water exposure

Ironically, too much water can also weaken nails. Repeated wet–dry cycles cause the nail plate to expand and contract. Over time, this stresses the layers.

Add cleaning products into the mix and the tips become even more fragile.

Filing technique

Filing back and forth may seem harmless, but it creates tiny tears along the edge. Later, those micro-tears turn into peeling.
