Why Do Fingernails Split Straight Down Instead of Chipping?

As people age, nails often become thinner and more fragile. Genetics may also influence nail strength, making some individuals naturally more prone to splitting.

Although these factors cannot be changed completely, gentle nail care may help reduce breakage.

Helpful Habits

  • Moisturize regularly
  • File nails gently
  • Avoid harsh chemicals whenever possible

7. Manicures, Acrylics, and Harsh Chemicals

Frequent cosmetic nail treatments may weaken the nail plate over time.

Potential causes include:

  • Acrylic nails
  • Gel manicures
  • Excessive buffing
  • Acetone-based nail polish removers

Acetone is particularly drying and may increase brittleness.

Ways to Minimize Damage

  • Take breaks between manicures
  • Use acetone-free polish removers when possible
  • Avoid aggressive filing or buffing
