Scalp psoriasis and Dandruff are two of the most irritating scalp problems that you could experience. While both of them are treatable, the process takes a lot of time and patience and each of them is markedly different. Let’s find out more.

Scalp Psoriasis Vs. Dandruff

Scalp psoriasis is a skin condition that causes red, itchy, and scaly patches on the scalp. It is a chronic autoimmune disease that causes the skin cells to multiply rapidly, resulting in the build-up of thick, scaly patches on the scalp. These patches can be dry or moist and may bleed if scratched. In severe cases, scalp psoriasis can lead to hair loss.

Dandruff is a common scalp condition that causes flaky, itchy, and oily or dry skin on the scalp. It is caused by a yeast-like fungus called Malassezia that thrives on the oils secreted by the hair follicles. Dandruff can be caused by a variety of factors, including stress, hormonal changes, poor diet, and certain hair products. While it is not a serious condition, severe dandruff can be embarrassing and difficult to manage.

Causes of Scalp Psoriasis

Scalp psoriasis is an anomaly of the immune system that causes skin cells to regenerate at abnormally fast rates. This results in red patches and scaling. It is believed that both environmental and genetic factors are responsible for scalp psoriasis. It has been found that if you have at least one member of your family suffering from scalp psoriasis then you have a greater possibility of developing the same condition.

People susceptible to scalp psoriasis may not show any symptoms for years until it is triggered by an external agency. The most common reasons for scalp psoriasis include:

  • Throat or skin infections
  • High-stress levels can weaken your immune system and the possibility of developing psoriasis
  • Cold, dry conditions
  • A skin injury brought about by cut, bite or sunburn
  • Excess alcohol consumption
  • Smoking
  • Certain strong medicines for conditions such as malaria and high blood pressure
  • Withdrawal symptoms after stoppage of corticosteroids.

Causes of Dandruff

The skin cells on our scalp are in a process of constant regeneration and old skin is constantly flaked out and replaced with new skin. When this process of flaking is expedited and more white flakes are visible, people are said to be suffering from dandruff problems.

Dandruff is not directly connected to your hair or its hygiene, but it has more to do with the condition of your scalp skin. Dandruff can happen because of a variety of causes including:

  • Oily skin
  • Dry skin
  • If you do not shampoo regularly and excess skin cells develop
  • The Malassezia fungus that feeds on scalp oil
  • Contact dermatitis, wherein the person has an unfavourable reaction to certain hair products.
  • It could also be the result of hormonal issues.
  • Could be due to pitta dosha

Dandruff related problems give you an itchy scalp as a result of the accumulation of skin flakes which could worsen in cold and dry weather. Severe stress leads to more dandruff issues and could cause extensive hair loss. Dandruff can cause irritation, itchiness, flakiness, dryness and inflammation and can get aggravated by stress and weather.

Treating Scalp Psoriasis 

Though there is no cure for scalp psoriasis it is possible to get it under control with the help of several treatment processes. The treatment will depend on

  • The severity of the problem
  • How your body has responded before (if this is a relapse)
  • The presence of psoriasis in other parts of your body
  • The density of your hair.

The medicines are generally administered directly onto the scalp whether orally or with the help of injections. Phototherapy or light treatment techniques have also become very popular nowadays. If the medication does not prove to be effective the doctor may suggest a combination. The first step is to remove the scales which will make it convenient for the other medicines to work their magic.

  • Several OTC products contain salicylic acid, zinc pyrithione, selenium sulphide and lactic acid which are extremely effective in loosening the scales.
  • You can then further loosen the scales with a brush
  • Shampoo to remove the scales with a product containing any of the above-mentioned ingredients
  • After removal of the scales apply the creams in those places while they are still damp to hold in the moisture.

Takeaway

Scalp psoriasis and dandruff are two distinct scalp conditions with different causes and characteristics. Scalp psoriasis is a chronic autoimmune disease that leads to red, itchy, and scaly patches on the scalp due to the rapid multiplication of skin cells. On the other hand, dandruff is a common scalp condition caused by a yeast-like fungus called Malassezia, resulting in flaky, itchy, and oily or dry skin on the scalp. While scalp psoriasis may lead to severe complications such as hair loss and psoriatic arthritis, dandruff is generally less severe and may cause emotional distress and itching. Proper diagnosis is crucial, as treatment approaches vary between the two conditions.

For scalp psoriasis, medical treatment with topical steroids, coal tar, or salicylic acid is commonly prescribed, and phototherapy or light treatment techniques can be effective. Managing underlying triggers, such as stress and cold weather, can also help alleviate symptoms. Dandruff treatment options include anti-dandruff shampoos containing active ingredients like zinc pyrithione or ketoconazole, topical treatments with coal tar or salicylic acid, and lifestyle changes like maintaining good scalp hygiene and a healthy diet. Home remedies like aloe vera, apple cider vinegar, turmeric, baking soda, and coconut oil can also provide relief. Proper scalp care and a healthy lifestyle can help prevent and manage both scalp psoriasis and dandruff effectively. Traya offers specific solutions for dandruff, and while scalp psoriasis cannot be fully cured, our Hair Ras vitamin aids in improving internal health, potentially providing relief from symptoms and reducing flare-ups.
