2. Hydration Issues

Dehydration can have a big influence on your nails, making them brittle and more likely to split. Drinking enough of water throughout the day helps keep nails flexible and strong.
3. Environmental Factors

Chemical Exposure
Regular exposure to harsh chemicals, such as cleaning agents, nail paint removers, and detergents, can gradually damage your nails. Wearing gloves while cleaning and using acetone-free nail polish removers can help to reduce these effects.
Weather Conditions
Extreme cold or dry weather can dehydrate your nails and cause them to become brittle. Using a moisturizer and wearing gloves during the colder months can provide protection.
4. Health Conditions

Thyroid Dis.e.a.ses
Both hyperthyroidism and hypothyroidism can lead to brittle nails. If you suspect your thyroid is the problem, a simple blood test can help diagnose the illness and provide suitable treatment.
