if you are suffering severe dandruff or skin problems agitated. you should read this.
who knows. you are one of psoriasis sufferers.
What is Psoriasis
Psoriasis (sore-EYE-ah-sis) is a medical condition that occurs when skin cells grow too quickly. Faulty signals in the immune system cause new skin cells to form in days rather than weeks. The body does not shed these excess skin cells, so the cells pile up on the surface of the skin and lesions form.
Sign and symptoms
Psoriasis typically looks like red or pink areas of thickened, raised, and dry skin. It classically affects areas over the elbows, knees, and scalp. Essentially any body area may be involved. It tends to be more common in areas of trauma, repeat rubbing, use, or abrasions.
Psoriasis has many different appearances. It may be small flattened bumps, large thick plaques of raised skin, red patches, and pink mildly dry skin to big flakes of dry skin that flake off.
- Psoriasis is a chronic inflammatory skin disease.
- Psoriasis has no known cause.
- The tendency toward developing psoriasis is inherited in genes.
- Psoriasis is not contagious.
- Psoriasis gets better and worse spontaneously and can have periodic remissions (clear skin).
- Psoriasis is controllable with medication.
- Psoriasis is currently not curable.
- There are many promising therapies, including newer biologic drugs.
- Future research for psoriasis is promising.
What causes psoriasis?Psoriasis is not contagious. You cannot get psoriasis from touching someone who has psoriasis, swimming in the same pool, or even intimate contact. Psoriasis is much more complex.
So complex, in fact, scientists are still studying what happens when psoriasis develops. We know that the person’s immune system and genes play key roles. In studying the immune system, scientists discovered that when a person has psoriasis, the T cells (a type of white blood cell that fights unwanted invaders such as bacteria and viruses) mistakenly trigger a reaction in the skin cells. This is why you may hear psoriasis referred to as a “T cell-mediated disease.”
This reaction activates a series of events, causing new skin cells to form in days rather than weeks. The reason T cells trigger this reaction seems to lie in our DNA. People who develop psoriasis inherit genes that cause psoriasis. Unlike some autoimmune conditions, it appears that many genes are involved in psoriasis.
Scientists are still trying to identify all of the genes involved. One of the genes that has been identified is called PSORS1 (SORE-ESS-1). This is one of several genes that regulates how the immune system fights infection.
Scientists also have learned that not everyone who inherits genes for psoriasis gets psoriasis. For psoriasis to appear, it seems that a person must inherit the “right” mix of genes and be exposed to a trigger. Some common triggers are a stressful life event, skin injury, and having strep throat. Many people say that that their psoriasis first appeared after experiencing one of these. Triggers are not universal. What triggers psoriasis in one person may not cause psoriasis to develop in another.
Who gets psoriasis?People worldwide develop psoriasis. In the United States, nearly 7.5 million people have psoriasis and about 150,000 new cases are diagnosed each year. Studies indicate that psoriasis develops about equally in males and females. Research also shows that Caucasians develop psoriasis more frequently than other races. A study conducted in the United States found the prevalence was 2.5% in Caucasians and 1.3% in African Americans.
A family history of psoriasis seems to increase the risk of developing psoriasis. It is important to know that a family history of psoriasis does not guarantee that someone will develop psoriasis.
When do people get psoriasis?Psoriasis can begin at any age, from infancy through the golden years. There are, however, times when psoriasis is most likely to develop. Most people first see psoriasis between 15 and 30 years of age. About 75% develop psoriasis before they turn 40. Another common time for psoriasis to begin is between 50 and 60 years of age.
Does psoriasis affect quality of life?For some people, psoriasis is a nuisance. Others find that psoriasis affects every aspect of their daily life. The unpredictable nature of psoriasis may be the reason. Psoriasis is a chronic (lifelong) medical condition. Some people have frequent flare-ups that occur weekly or monthly. Others have occasional flare-ups.
When psoriasis flares, it can cause severe itching and pain. Sometimes the skin cracks and bleeds. When trying to sleep, cracking and bleeding skin can wake a person frequently and cause sleep deprivation. A lack of sleep can make it difficult to focus at school or work. Sometimes a flare-up requires a visit to a dermatologist for additional treatment. Time must be taken from school or work to visit the doctor and get treatment.
These cycles of flare-ups and remissions often lead to feelings of sadness, despair, guilt and anger as well as low self-esteem. Depression is higher in people who have psoriasis than in the general population. Feelings of embarrassment also are common.
Knowledge is powerAs psoriasis is a life-long condition, it is important to take an active role in managing it. Learning more about psoriasis, seeing a dermatologist to discuss treatment options, and developing a healthy lifestyle can help people live life to the fullest.

Topical therapy for scalp psoriasis includes corticosteroids, tazarotene, anthralin, calcipotriol/calcipotriene and tars. Topical medications are available in the form of creams, lotions, ointments, gels, foams and shampoos. These medications can be applied once or twice daily, for several weeks or months.
psoriasis free for life
