Do you wash dishes often without gloves? Use hand sanitizer multiple times a day? Work with cleaning products?
Excessive exposure to water, detergents, and harsh chemicals can strip natural oils from your nails, making them dry and prone to splitting. In the United States, many people experience brittle nails due to frequent handwashing, especially after the pandemic increased hygiene awareness.
Wearing gloves while cleaning and applying a quality moisturizer after washing your hands can significantly reduce breakage.
3. Thyroid Imbalance
In some cases, brittle nails may indicate a thyroid issue. Both hypothyroidism and hyperthyroidism can affect nail growth and strength. When the thyroid gland is not functioning properly, it disrupts the body’s metabolism, which can impact hair and nail health.
If brittle nails are accompanied by symptoms like fatigue, weight changes, hair thinning, or sensitivity to temperature, it may be worth discussing thyroid testing with your healthcare provider.
4. Aging and Hormonal Changes
As we age, nail growth slows down and moisture levels decrease. This naturally makes nails more prone to splitting. Hormonal shifts, especially during menopause, can also affect nail strength due to changes in estrogen levels.
While aging is unavoidable, maintaining proper hydration and using nail-strengthening treatments can help reduce damage.
5. Overuse of Nail Products
Gel manicures, acrylic nails, and frequent polish removal with acetone-based removers can weaken the nail plate over time. Repeated filing and buffing also thin the nail surface, making it easier to crack.
If your nails improved during a break from salon treatments, that’s a strong clue your routine may be contributing to the issue. Giving your nails time to recover can make a noticeable difference.
