Hair Loss? It May Be Iron Deficiency
Too Little Iron in Blood of Men and Women Shedding Hair

May 17, 2006 - If you're losing hair, you may have an iron deficiency.
A review of 40 years of research shows that iron deficiency has a much
closer link to hair loss than most doctors
realize. It may be the key to restoring hair growth, Cleveland Clinic
"We believe that treatment for hair loss is enhanced when iron
deficiency, with or without anemia, is treated," Leonid Benjamin Trost, MD; Wilma Fowler
Bergfeld, MD; and Ellen Calogeras, RD, MPH, write in the May issue of the
Journal of the American Academy of Dermatology.
It's a controversial issue. Not every study shows a link between iron
deficiency and hair loss. Trost says there's not enough hard evidence -- yet --
to make iron-deficiency screening a routine procedure for people with hair
But study researcher Bergfeld has been doing this for years. And she's
finding that whatever the cause of hair loss -- for both women and men --
having too little iron in the blood makes it worse.
"What Dr. Bergfeld has found in decades of experience, is when she
treats patients for iron deficiency --even in the absence of anemia -- it can
maximize their ability to regrow hair," Trost tells WebMD. "It is not
the silver bullet for baldness, but it can definitely help maximize how a
patient regrows hair."
The Cleveland Clinic isn't alone in doing this. George Cotsarelis, director
of the University of Pennsylvania Hair and Scalp Clinic, has studied iron
supplementation in women with various forms of hair loss.
"From our clinic's experience, it is clear to me that if you replenish
hair-loss patients' iron stores with iron supplements, they are more likely to
regrow hair, or at least stop hair shedding," Cotsarelis tells WebMD.
"And they don't have to be anemic. That is the biggest mistake doctors
An even bigger mistake would be for balding people to take iron supplements
on their own. Unless you have iron deficiency -- diagnosed by a doctor -- iron
supplements can lead to a very dangerous condition from iron overload.
Hair Loss May Be a Symptom of Serious Illness
A sensitive way to check total body iron stores is to measure the amount of
ferritin in the blood. Ferritin is a protein that plays an important role in
iron storage. As a general rule, the less ferritin in the blood, the less iron
a body has stored up.
