It is said that nail pitting can affect up to 50 per cent of people who are suffering from this condition. Dr. Jailman suggests that if one is experiencing any pitting or dents in the nails, one should consult with the doctor.

 

6. Ridged nails

According to Dr. Anthony, the reason people will see horizontal ridges on their nails is that there could be direct trauma to the nail, or it could be a cause of a more serious illness. He said that the reason for this is because the body is focusing its energy on fighting the illness rather than the nails.

He elaborates that melanoma that comes from the nail unit is extremely serious and it can also cause a black line or stripe on the nail. He said that if one notices this, one should contact the doctor immediately.
