All Bloods/Hormones WNL but 1yr sudden 75% hair loss

[ivm1]

I started to suddenly lose my hair in Central Asia, summer 2007, after arriving there 6 months earlier. I returned home to US in March, 2008. All bloods and hormone levels are normal...thyroid nodules benign, thyroid levels normal. Endocrinologist, dermatologist are not concerned or offering treatment or answers, except steroid therapy, which I refuse. Scalp biopsy has not been done and I am not on any meds.

I had Hepatitis B&C vaccine in the summer, 2006, before going, as well as vaccines for Cholera, Pneumonia, Typhoid. The heavy metals (lead, mercury), water pollution, potable water disinfection, lack of hygiene and garbage disposal, air pollution including > 1000 (?measured in mcg/dL?)formaldehyde, etc. may be causes but blood levels for lead/mercury below 4.... It is now 8 months since returning home and hair loss is continuing, so much so that a blonde newborn has more than I do.

Seems that if it is stress/ ecology/ pollution related, hair loss should have stopped as I returned to US 8 months ago. However, the thinning is persisting and you can now see my scalp through the hair at the hairline. Need advice and referral in NYC-NJ metro area. Thank you.
