What causes the tip of a nail to split down the middle?

The splitting of a nail tip down the middle is primarily caused by using a tip that is narrower than the nail plate. When a tip is too narrow, it does not provide adequate support along the sides of the nail. This lack of proper coverage can lead to increased stress on the nail when it is flexed or when pressure is applied. Consequently, this stress may cause the nail to split as it fails to withstand the forces exerted on it.

It is important to choose a nail tip that matches the width of the natural nail plate to ensure the structural integrity of the nail extension. This alignment minimizes the risk of damage, allowing for a more durable and aesthetically pleasing application.

Additionally, while factors like excessive pressure during filing, incorrect adhesive use, and moisture levels can lead to other nail issues, they are not directly related to the specific problem of a nail tip splitting down the middle. Proper technique and material selection are crucial in maintaining the health and appearance of nail enhancements.
