Severe Dandruff
Severe cases of dandruff are caused by a disease called seborrhoeic eczema or seborrhoeic dermatitis.
Seborrhoeic
dermatitis causes greasy, bran-like scale. The seborrhoeic area - the
scalp, the skin around the nose, the lines on the cheeks, the eyebrows,
the ears and the torso - may also be red and itchy.
Seborrhoeic
dermatitis becomes worse during the winter and tends to improve during
the summer when sunlight relieves the symptoms. It can vary from mild
cases, which are only a problem in winter, to more severe cases where
flaking occurs in places other than just the scalp.
The
fungus Pityrosporum ovale is a significant factor in seborrhoeic
dermatitis. Doctors don't know exactly why, but anti-fungal treatment
helps ease the condition.
As well as seasonal changes, stress and serious illnesses can cause an increase in the production of scale.
A
sudden, strong tendency to flaking or seborrhoeic dermatitis in a
middle-aged person who has never had such problems before can be a sign
of HIV infection.
Some people with severe dandruff may have psoriasis.
Can dandruff be prevented?
It can be difficult to prevent dandruff completely, but it can be controlled. The condition may also improve as you age.
Treatment In Severe Cases
In severe cases dermatologists will prescribe a special ointment or
lotion to treat the problem. It is generally agreed that drugstore
products which contain Zinc pyritheone or selenium sulfide are the most
effective in ridding the scalp of dandruff flakes. If a scalp shows
signs of redness, swelling, scabbing, or gooeyness - accompanied by
flakes, in all likelihood there could be another scalp disease involved
like psoriasis or ringworm (yucky, but can be treated). With any of
these symptoms it is important to see your health care provider
immediately!
