Dandruff and psoriasis
Dry and shaky skin on the scalp can be uncomfortable. These rashes can be caused by dandruff or psoriasis, which are two very different conditions:
Dandruff (also known as seborrhea) can usually be treated relatively easily and is rarely a serious medical problem.
On the other hand, psoriasis is a chronic condition without a current cure and that can cause a lot of concerns.
How does dandruff develop?
Dandruff is a condition marked by dry patches on the scalp. These patches of skin can often fall from the hair to the shoulders.
Dandruff is usually due to the body’s excessive reaction to the presence of normal fungi on the skin. This inflammation leads to overproduction of skin cells, leading to small detached pieces of skin. If this is the cause, they are usually small and you may have dry skin on other parts of the body as well.
Washing your hair with a harsh shampoo or using too many chemicals in your hair can sometimes irritate the scalp and lead to dandruff.
A fairly common condition called seborrheic dermatitis is the cause of many cases of dandruff. It is characterized by red and oily skin spots that leave yellow patches on the scalp. These are often larger than those of dandruff that can arise from dry skin.
Seborrheic dermatitis can also cause irritated, irritated spots elsewhere on the face and body, which can make you think you have psoriasis.
How does psoriasis develop?
Unlike dandruff, psoriasis is an ingrained problem in the immune system. It is considered an autoimmune disease, meaning special proteins called autoantibodies mistakenly attack healthy tissues.
This attack causes the production of skin cells to accelerate, creating an unhealthy and abnormal growth of new skin that accumulates in dry and light spots on the body, including the scalp.
Normally, dead skin falls into small, thin fragments of the outermost layer of skin. Neither you nor anyone else can ever say you are losing dead skin. New and healthy skin cells are forming beneath the skin surface and, within a few weeks, rise to the surface to replace dead skin.
If you have psoriasis, that process accelerates to various spots on the body and there is no time for the dead skin to pass its normal decline. This causes dead skin cells to accumulate on the surface. This usually happens in:
Psoriasis can take many different forms. Sometimes the skin may look cracked and dry. Other times it may redden and become more crusty.
Dandruff can usually be treated with medical shampoo. It is also important to follow the instructions of each shampoo you use. Some can be used several times a week, while others can only be used once a week. You may also need to change shampoos, as one may become less effective over time.
Psoriasis can be treated with topical, oral medications and injections, many of which are steroids, but they only serve to make the symptoms somewhat milder. There is no current cure.
Drugs known as disease-modifying antirheumatic drugs (DMARDs) are given to people with moderate to severe psoriasis. Light therapy, which targets the appearance of psoriasis with specially directed ultraviolet light, can also help treat the symptoms of psoriasis.
Biologists can be used to treat various forms of moderate to severe psoriasis. These injectable drugs work by blocking inflammatory proteins.
