Nails as an indicator of general health

Nails can be helpful in gauging your general health and should be a healthy pink color. However, some signs may indicate problems, and with this in mind we have listed a few general indications, where your nails may show possible problems.

Please note - this information regarding your nails mirroring your general health, is provided for information purposes only, and should NOT be used to diagnose or treat any illness. If in doubt regarding your health, please consult your doctor.

Also keep in mind that your nails may look a particular way for another reason totally unrelated to your health, but could be due to mechanical or environmental influences. Your beauty therapist and manicurist should also be able to guide you in this field.
