Dandruff
Dandruff
is the dead cell layers of the scalp coming off like scale, visible
to the naked eye too.
Dandruff may also be caused by fungus (Pity-sporum-ovalis) that
can be found on everybody's scalp. If this fungus multiplies in
large quantity the natural cell renewal cycle of the scalp speeds
up. Then the dead epithelial cells stick closely together and leave
more quickly.
Dry dandruff
The micro flora of the scalp is upset and because of this, the
defensive system doesn't function. As a result, the Pity-sporum-ovalis
fungus spreads and infects the cells, which are on the scarfskin
layer. The dandruff plates on the scalp are not greasy and come
away easily from the skin quickly. They collect on and fall from
the hair.
Greasy
dandruff
The dandruff plates are greasy and stick to the scalp. The patient
complains about itchiness
If the greasy dandruff layer stays on the hairy scalp for a longer
time, then the respiration of the skin slows down and hinders the
growth of the hair.
Seborrhoea dermatitis
Fungus irritates the glands, which become inflamed and the skin
becomes pink. Fatty acid is produced which is irritant and causes
inflammation. The dandruff plates become larger and larger. This
is a recurring condition but it can be without symptoms.
Dandruff can have external or internal causes:
- Stress
- Changes in climate
- Wearing hats
- Use of alkaline products
- Upsetting the PH value
