My fingernails keep splitting straight down instead of chipping. What causes this?

As we age, changes in nail texture and strength are common. The nail matrix can thin over time, leading to more frequent splitting and breakage. Additionally, genetics play a role in nail health, with some individuals naturally predisposed to more fragile nails.

While we cannot change our genetic makeup or halt the aging process, adopting protective measures and maintaining a proper nail care routine can mitigate some of these effects. Regular filing, moisturizing, and avoiding harsh treatments can help preserve nail integrity.

Frequent use of nail polish, acrylics, and gel manicures can weaken the nail plate over time. The chemicals in nail products, particularly those used for removal like acetone, can dry out nails and contribute to splitting.

Opting for gentler nail care options and allowing nails to breathe between manicures can prevent excessive damage. If acrylics or gels are a must, consider giving your nails a break every few weeks to recuperate and strengthen.

Certain skin and nail disorders can cause or exacerbate nail splitting. Onychorrhexis, characterized by longitudinal ridges and splitting, is often linked to skin conditions like psoriasis and eczema. These conditions can affect the nail matrix and disrupt normal growth.

Managing these underlying conditions with appropriate medical treatments can improve nail health. Dermatologists can provide targeted therapies to reduce inflammation and promote healthier nail growth.

Nails can often reflect systemic health issues. Conditions such as thyroid disorders, liver disease, and circulation problems can manifest as splitting nails. Additionally, certain medications, particularly those used in chemotherapy, can affect nail integrity.

Monitoring your nail health can provide clues to potential medical conditions. If you notice persistent nail changes alongside other symptoms, it is advisable to seek medical evaluation to rule out or address any underlying health concerns.
