11 questions to ask your doctor to pinpoint the cause

If you notice unusual hair loss, see your doctor (preferably a dermatologist) as soon as you can. Hair loss and thinning can lead to fear, anxiety, and depression -- all of which can seriously affect physical health. Proper treatment can help reverse hair loss and, in doing so, erase much of the psychological discomfort you are experiencing.

You can help your doctor or dermatologist arrive at a more accurate diagnosis. Prior to your appointment, scribble down the facts behind your hair loss and general health by answering these questions:

• How long have you been losing your hair?
• When did the hair loss start?
• Is your hair coming out by the roots or breaking off?
• Have you had any recent illnesses or surgery?
• Do you have a family history of baldness?
• Are you taking any medications or supplements?
• What is your normal diet?
• Have you experienced sudden, unexplained weight loss?
• Have you had a recent pregnancy, hysterectomy, or experienced any menstrual irregularities?
• What kind of hair care products do you use, including shampoos, conditioners, chemicals (rinses, bleaches, straighteners, or permanents)?
• What do you use to style your hair (electric rollers, dryers, hot curlers, regular rollers, teasing, or use of rubber bands)?

In addition, bring in a photograph of yourself taken a few years earlier when you had more hair, or a handful of hair that has recently fallen out.
