Why does it look like there are cracks on my fingernails?
There could be several reasons why your fingernails appear to have cracks. One common reason is dehydration, which can cause your nails to become brittle and prone to breaking or cracking. Exposure to harsh chemicals, such as cleaning products or nail polish remover, can also weaken your nails and lead to cracks.

Another possible cause is a deficiency in certain nutrients, such as biotin or vitamin D, which are essential for nail health. Medical conditions, such as psoriasis or thyroid problems, can also cause nail changes, including cracking.

If the cracks on your nails are accompanied by other symptoms, such as pain, swelling, or discoloration, it's important to consult a healthcare professional to rule out any underlying medical conditions. In the meantime, you can try using a moisturizer on your hands and nails regularly, avoiding harsh chemicals, and eating a well-balanced diet rich in nutrients to support nail health.
