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 or scalp.
Use this guide to see what separates myth from fact when it comes to your health and your hair.

White Flakes Pose No Health Risk
Risk factors include oily skin, stress, obesity, cold, dry weather and eczema or psoriasis (photo: senseornosense)
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
Try using an antidandruff shampoo daily
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.
Severe cases may need a prescription steroid or antifungal medicine (photo: webmd)
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 problems, it’s treated the same as dandruff, with antidandruff shampoos.
Severe cases may need a prescription steroid or anti fungal medicine.
You May Shed More Than You Think
About 90 per cent of your 100,000 hair follicles are producing hair at any given time (photo: zanobya)
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 per cent of your 100,000 hair follicles are producing hair at any given time.
The other 10 per cent 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, 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
Alopecia areata isn’t harmful or contagious (photo: belgraviacentre)
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, 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 per cent 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 Rogaine (minoxidil) and Propecia (finasteride).
Hair loss in women is usually most common on top of the head (photo: kraussderm)
Hair loss in women may mean hair thinning all over the head, but 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 may help hair growth and prevent thinning.
Avoid Sun Damage to Hair
Too much sun can turn your hair into a brittle, dry mop that breaks and splits easily
Too much sun can turn your hair into a brittle, dry mop that breaks and splits easily.
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.
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-cal 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 Grey Hair Is Genetic

Going grey isn’t always related to aging. If you’re not yet 40 and see more than a few grey hairs, chances are it runs in your family.
Grey usually isn’t a sign of poor health, though anemia, thyroid issues, vitamin B-12 deficiency, and vitiligo can cause premature greying.
You can highlight or colour hair to cover the grey, but beware: some people are sensitive to the dye’s chemicals.
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, colouring, 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 over style to the point that your only option for healthy hair is to cut it off and start over.

A Surprising Side Effect
Some medications list hair loss as a side effect (photo: steadyhealth)
Among the medications that list hair loss as a side effect are anticlotting drugs, cholesterol-lowering drugs, antidepressants, non-steroidal 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
Rubbing your scalp may help release tension (photo: hairgrowthremediesnow)
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
Hair analysis can detect poisons but findings can be inconsistent and varied (photo: blogspot)
Some companies claim they can analyse 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.
