How can I test whether my hair is healthy?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Your outer beauty often reflects your inner health, and that's especially true when it comes to hair. I recommend a 10-second hair test to see if yours is healthy. Grab some hair, about as much as you would put in a straw. Grab it at the very bottom, right where it comes off the scalp, and pull up. Now look at how many hairs you have in your hand. A straw amount of hair is about 60 hairs. If you're pulling out more than six hairs, then you're starting to lose hair a little rapidly.
