Does Bad Hair Mean Bad Health?
Is your hair trying to tell you something about your
health? Maybe. Some conditions and medications affect your
body as well as your hair. In other
cases, you may just need to take better care of your hair and scalp. Use this pictorial guide to see what
separates myth from fact when it comes to your health and your hair.
White Flakes Pose No Health Risk
Dandruff isn’t contagious.
So how do you get it? Doctors
aren’t sure, but one theory is that it may be due to an overgrowth of a
fungus. Other possible risk factors
include oily skin, stress, obesity, cold, dry weather, and having eczema or
psoriasis. Although it’s embarrassing –
and the itching can be bothersome – dandruff isn’t harmful.
Tips for Dandruff Treatment
To decrease the buildup of dandruff’s dead skin cells, try
using an antidandruff shampoo daily.
Leave shampoo on for 5 minutes, then rinse well. You may need to try several dandruff shampoos
to find one that works best for you. if
one stops working, try another. If that
doesn’t help, call your doctor.
Yellow Dandruff
If the dandruff flakes you see are greasy and yellow, you
may have seborrheic dermatitis. It’s an
inflammatory skin condition that can occur where there are lots of oil glands,
like the scalp and face. Though seborrheic
dermatitis is related to hormones, fungus and even some neurological conditions
like Parkinson’s disease or HIV, these conditions are all treated the same as
dandruff; with antidandruff shampoos.
You May Shed More Than You Think
It’s not a perfect measure, but some experts estimate that
we may shed up to 100 or more hairs a day.
That’s not cause for alarm, nor does it mean you’re going bald. About 90% of your 100,000 hair follicles are
producing hair at any given time. The
other 10% are in a resting (telogen) phase, and the hair falls out after about
2 to 3 months. It’s replaced by new
hair, and the growth cycle starts over again.
What Causes Telogen Effluvium?
A shock to your system – surgery, vaccinations, giving
birth, some medications, crash diets, severe stress, thyroid problems – can
push hair into its resting, or telogen, state.
About two months later, you may see hair falling out and thinning – a
condition called telogen effluvium, sometimes described as hair “coming out in
handfuls.” In most cases, new hair
starts growing right away.
An Attack on Hair Follicles
In alopecia areata, your immune system mistakenly attacks
hair follicles, causing hair to fall out – often suddenly. Most people will have one or two bald
patches, which can be treated easily with injections but in some cases all body
hair falls out. alopecia areata isn’t
harmful or contagious, but it can be tough psychologically. Hair may grow back on its own, and treatment
may help it grow back more quickly.
Unfortunately, some people may experience alopecia areata repeatedly.
Genes Cause 90% of Male Hair Loss
Though hereditary, the trait may be more influenced by your
mother’s family than your father’s. So a
look at your maternal grandfather’s locks may give you a better clue about the
future of yours. Male pattern baldness
often starts with receding hair at the temples, then on the crown, leaving a
horseshoe-shaped ring of hair around the sides of the head. Medications to slow hair loss include
finasteride (Peopecia) and minoxidil (Rogaine).
Female-Pattern Baldness
Age-related thinning may mean hair thinning all over the
head, but pattern hair loss is usually most common on top of the head. Unlike men, women rarely go bald, and they
tend to lose hair more slowly than men do.
Contrary to popular belief, longer hair won’t put a strain on the roots,
causing more to fall out. nor will
shampooing pull hair out – it just gets the ones that were falling out
already. Minoxidil 5% applied once daily
may help hair growth and prevent thinning.
Spironolactone and Flutamide (oral medications) can also be used in
women.
Avoid Sun Damage to Hair
Too much sun can turn your hair into a brittle, dry mop that
breaks and splits easily. This is
especially true in those with blonde or grey hair. And if you already have thinning hair, you
risk a sunburn on your scalp. Choosing
hair care products with sunscreen provides some protection, although it can be
hard to coat your hair evenly. That’s
why it’s a good idea to wear a hat when you’re out in the sun – especially if
your scalp is exposed. Choose a hat made
of sun-protective fabric with UPF-30 (ultraviolet protection factor).
Luscious Locks Need Nutrients
Could a crash diet cost you your hair? In extreme cases, it could. Your hair needs protein and iron to stay
healthy, along with omega-3 fatty acids, zinc, and vitamin A, but not too much
– which can promote hair loss. Very
low-calorie diets are often lacking in sufficient nutrients and can stunt hair
growth or leave hair dull and limp. If
the nutritional deficiency is big enough – like for someone with an eating
disorder – hair can fall out.
A Hair- and Heart-Healthy Diet
Help keep hair shiny by eating salmon and walnuts for
omega-3 fatty acids; spinach and carrots for vitamin A; brazil nuts for
selenium; and oysters and cashews for zinc.
All help maintain scalp and hair health, as do low-fat dairy, whole
grains, and vegetables. Double the
results : Foods good for your hair are
also good for your heart.
Premature Gray Hair Is Genetic
Going gray isn’t always related to aging. If you’re not yet
40 and see more than a few gray hairs, chances are it runs in your family. Gray usually isn’t a sign of poor health,
though anemia, thyroid issues, vitamin B12 deficiency, and vitiligo can cause
premature graying. You can highlight or
color hair to cover the gray, but beware:
Some people are sensitive to the chemicals in dyes. The result could be an itchy, burning scalp.
Traction Alopecia Damages Follicles
Pulling hair too tight – as can happen with ponytails,
braids, and cornrows – can damage hair follicles and cause hair to break or
fall out. Hair extensions and hairpieces
can sometimes cause traction alopecia, too, because their extra weight pulls on
existing hair. Changing your hairstyle
usually lets hair grow back. pulling
hair back tightly for a long time, though, can lead to permanent hair loss.
Overstyling Weakens Your Hair
Blow drying, using a flat iron, coloring, bleaching, even
over-brushing – all can damage the outer layer (cuticle) of your hair. When the inner core of hair is exposed, your
locks become dry and dull. Although it
doesn’t cause any permanent health damage, you can overstyle to the point that
your only option for healthy hair is to cut it off and start over. When it comes to your hair, doing less leads
to healthier tresses.
A Surprising Side Effect
Among the medications that list hair loss as a side effect
are anticlotting drugs, cholesterol-lowering drugs, antidepressants,
nonsteroidal anti-inflammatory drugs (NSAIDs), and drugs for menopause, birth
control, and antibiotics. Usually, hair grows
back when the medication is stopped, but may not in some cases.
Scalp Massage Feels So Good
There’s no evidence that massaging your scalp will slow hair
loss or improve any scalp conditions – but it can do wonders to relieve
stress. Your scalp is covered with nerve
endings that make it super-sensitive to touch.
Rubbing your scalp may help release tension. Massage may also trigger the release of
feel-good hormones like dopamine and serotonin.
Hair Analysis Not Reliable
Some companies claim they can analyze hair clippings to see
if you are deficient in vitamins or have health problems. Although hair analysis can detect some
poisons like lead or arsenic, findings can be inconsistent and varied. Everything from air pollution to shampoo may
affect test results. The American
Medical Association is against hair analysis to determine treatment.
