Like all our skin we shed it naturally, little bits at a time and then the skin is renewed, from the bottom up pushing off the dead cells. It is a process and we all do it. Usually they are so small we do not even notice it when they shed off.
When we get dandruff also known as scurf, and medically known as Pityriasis capitis, the shedding of skin from our scalps increases in speed and those larger scales of skin are pushed off and they are sometimes in clumps which is visible to the eye. This process can even make our scalps itchy and thus instead of flakes falling off we encourage them with scratching to come off in greater quantity. This is the embarrassing white spots we get on our shoulders and work feverishly to smooth off our clothes.
It is estimated that at least 50-60% of all people around the age of 20 years old will have dandruff. It can of course occur at any age, but that is the most prevalent.
What causes dandruff?
There is really information overload about dandruff. Some say one thing, another says another. They contradict and change and then go back to saying it is all truth. All you can do is take each thing that you think might be the problem and see if it is by changing it in some way.
It is commonly thought that there are two different types of dandruff. I doubt if it really matters that you identify it like that but for ease it will be shown here that way. The first is internal and yes the second is external.
Internal-Things that cause dandruff from the inside of you
