See What Your Manicurist Sees When Looking at Your Fingernails!
The manicurist might not recognize the symptoms your fingernails portray. However, some practitioners of Eastern and Western Medicine or of Holistic Healing Modalities can identify health problems by looking at your fingernails before you cover them up with nail polish. 
Here are some resources before we continue. They help define our terms of Eastern, Western, and Complementary and Alternative Medicine (CAM / holistic healing). They also provide more pictures and links than I can include in this blog.
The National Institute of Health (NIH) compares Eastern and Western approaches to medicine and health.
An easier way to understand it may be found in the blog of a person who has practiced “all of the above.” Dr. Emili Kim describes his findings.
I
am neither a physician nor a practitioner of Eastern Medicine. However, I am certified in a number of holistic healing (CAM) methods. I can share what they know and what I know as you stare at your fingernails.

Ayurveda, Chinese medicine, alternative medicine, and now Western medicine often agree on the value of “reading” fingernails (and toenails), eyes, ears, and tongues in the diagnostic process.
