What Causes Hair Loss?
|
|
|
|
|
|
|
Nearly two, out of every three men will begin balding by the time ، they're 60 Most don't part with
|
|
their part willingly American males collectively, spend $1 billion a year trying to hang onto those
|
|
locks & while there's no cure for a shiny scalp,there are a lot of supposed causes that men worry
|
|
about more than they need to. Recent research suggests that the most common type of hair loss,
|
|
male pattern baldness , can be triggered by faulty hair - making progenitor cells in the scalp.
|
|
Researchers long believed, that men whose hair progressively thins — starting with a receding
|
|
hairline, and then stretching to the crown — lacked a sufficient, number of these cells . Rather, it
|
|
appears that the cells are merely, unable to complete their normal development, and mature to a
|
|
fully - functioning state. That finding, published last month in the Journal of Clinical Investigation,
|
|
could help researchers develop a treatment that reactivates and restores the malfunctioning cells.
|
|
Other potential contributors to hair loss include illness, age, genetics, and even primping habits.
|
|
Meanwhile, a flurry of myths contribute to men's anxiety, if not to baldness itself. "I get athletes who
|
|
think helmets caused their hair to fall out, and men who say it's because, their mothers rubbed their
|
|
heads with black tar soap, " says dermatologist Gary Hitzig, author of help and kope for hair loss.
|
|
Neither helmets nor soap are at fault, he says. And more blame may get heaped on mothers than
|
|
they deserve.
|
|
U.S. News gets to the bottom of nine common beliefs about hair loss. Here's the bald truth:
|
|
1. Not entirely true. While the primary baldness gene is on the X chromosome , which men get only
|
|
from their mothers other factors are also in play.The hereditary factor is slightly more dominant
|
|
on the woman's side , but research suggests that men who have a bald father are more likely to
|
|
develop male pattern baldness than those who don't.
|
|
2. On the contrary, hair loss can strike in the teens and is common among 20 - and 30-year-olds.
|
|
The earlier it begins, the more severe it will likely become.
|
|
3. Good news for men who rely on caps to cover their shiny crowns: They're not causing any harm.
|
|
Dirty hats can, however, lead to a scalp infection, which in turn accelerates hair loss, so either make
|
|
sure yours is clean or rotate frequently.
|
|
4.True—with a catch. Physical or emotional stress " will never cause you to lose hair you wouldn't
|
|
have lost anyway," Hitzig says."If the hair is not meant to be lost, it will grow back " That said, it can
|
|
accelerate balding.Rapid shifts in weight—whether pounds are gained or lost—can also contribute to
|
|
of hair loss.
|
|
the likelihood No need to forgo the products—they don't cause balding, and neither does shampoo,
|
|
washing your hair frequently, or dandruff. But some men tease their hair and use curling irons,which
|
|
could speed up the process. "It's the over-mechanical utilization of hair that can be problematic,"
|
|
Sadick says.
