About This Quiz

Dandruff is a pretty common -- and embarrassing -- condition. The good news is, treatment is easy: Some dandruff shampoo should do the trick for most people. But what happens when your shampoo stops working? Take our quiz and find out.

If you have dandruff, it's probably because you're shampooing too much.

Excess shampooing -- or lack of it -- does not cause dandruff. Some people just shed skin cells more than others.


Eczema can cause dandruff.

Eczema causes skin cells to shed at an increased rate -- and yes, a form of it can occur on the scalp.


A fungus called <i>Pityrosporum ovale</i> could also cause dandruff.

Yes, the fat-eating fungus <i>Pityrosporum ovale</i> could be the culprit -- when there are too many of them on your scalp, they start eating the oil from hair follicles, which might make skin cells die too fast and flake off.


Most people have this fungus on their scalps, but people with dandruff tend to have more than others.

Pityrosporum ovale is found on the scalps of most healthy adults, but more so on people with dandruff.


If your dandruff flakes are yellowish and greasy, it could be a sign of psoriasis of the scalp.

Yellowish and greasy = sebbhorea. Large silvery scales = psoriasis of the scalp.


People with ALS sometimes have more <i>Pityrosporum ovale</i> on their scalps than other people do.

The scalps of people who have Parkinson's Disease are sometimes overpopulated with the <i>Pityrosporum ovale</i> fungus.


Coal tar is a common ingredient in antidandruff shampoos.

Sounds weird, but it's true. Neutrogena T-Gel shampoo is one example of a coal-tar antidandruff shampoo.


When you're using an antidandruff shampoo, you should rinse it out immediately after lathering.

Doctors actually recommend letting an antidandruff shampoo work for about five minutes before you rinse it out.


If a certain antidandruff shampoo works for a while and then stops working, you should see a doctor.

No need to call in the authorities -- if one brand stops being effective, try another.


Cradle cap is a form of dandruff in babies.

Cradle cap -- when babies develop a scaly scalp -- isn't pretty, but it usually clears up with time and minimal treatment.
