Why is my hair falling out?
It’s true that men are more likely to lose their hair than women, mostly due to male pattern baldness (more on that later).
But thinning hair and hair loss are also common in women, and no less demoralizing. Reasons can range from the simple and temporary—a vitamin deficiency—to the more complex, like an underlying health condition.
In many cases, there are ways to treat both male and female hair loss. It all depends on the cause. Here are some common and not-so-common reasons why you might be seeing less hair on your head.
Any kind of physical traumasurgery, a car accident, or a severe illness, even the flucan cause temporary hair loss. This can trigger a type of hair loss called telogen effluvium. Hair has a programmed life cycle: a growth phase, rest phase and shedding phase. “When you have a really stressful event, it can shock the hair cycle, (pushing) more hair into the shedding phase,” explains Marc Glashofer, MD, a dermatologist in New York City. Hair loss often becomes noticeable three-to-six months after the trauma.
Too much vitamin A
Overdoing vitamin A-containing supplements or medications can trigger hair loss, according to the American Academy of Dermatology. The Daily Value for vitamin A is 5,000 International Units (IU) per day for adults and kids over age 4; supplements can contain 2,500 to 10,000 IU.
What to do: This is a reversible cause of hair loss and once the excess vitamin A is halted, hair should grow normally.
Lack of protein
If you don’t get enough protein in your diet, your body may ration protein by shutting down hair growth, according to the American Academy of Dermatology. This can happen about two to three months after a drop in protein intake, they say.
