Scalp Psoriasis vs. Dandruff: How to Tell the Difference

Understanding the difference between dandruff and psoriasis is important as it can help you take the right course of action. While one is not a major issue, the other may require medical attention. Here, you will learn the key distinctions between scalp psoriasis and dandruff. You will also learn about dandruff and scalp psoriasis, how their symptoms differ, how to treat them, and when to see a healthcare provider.

What Is Dandruff?

Dandruff is a common skin problem that results in the shedding of skin flakes from the scalp. Although it is not contagious or a severe condition it can be embarrassing and challenging to treat. Mild dandruff can be treated with an anti-dandruff shampoo. If that does not work, a medicated shampoo may help. However, symptoms may return later.

What Is Scalp Psoriasis?

Scalp psoriasis is a medical condition caused by an autoimmune response. It results in the formation of raised, discoloured plaques on the scalp or the skin surrounding it. These plaques can be dry and itchy. Prescription and over-the-counter medications for scalp psoriasis are available to alleviate the symptoms. Scalp psoriasis causes the skin cells to reproduce too quickly, forming thick, discoloured patches of skin (plaques) on the scalp and other areas around it. These areas may include:

• Your hairline

• Your forehead

• The back of your neck

• The skin around your ears

How to differentiate between Scalp Psoriasis and Dandruff?

Dandruff usually affects the scalp and ears, but it can also affect other oily parts of the body, such as the eyebrows, eyelids, forehead, and nose crease. On the other hand, psoriasis can cause red and scaly spots on the elbows, knees, naval, or gluteal cleft and can also affect the nails. The appearance of both conditions is different. The scales of psoriasis are typically red but may appear silvery if someone has a lighter complexion and purple/grey on darker skin. Dandruff, on the other hand, appears as white flakes.

How Do You Treat Them?

Both dandruff and scalp psoriasis cannot be prevented, but healthcare providers can prescribe treatments and routines to reduce flare-ups if the itching and flaking persist. Although these two conditions are different, they share some treatments. Over-the-counter medicated shampoos, foams, conditioners, or lotions can easily banish most cases of dandruff. Similarly, topical treatments like medicated shampoos comprise the initial course of cure for scalp psoriasis. However, doctors may also prescribe vitamin D analogues and topical steroids for scalp psoriasis.

When To See a Healthcare Provider?

If you have been using over-the-counter solutions for several weeks as directed, but your condition has not improved, it is advisable to see a healthcare provider. While common dandruff can usually be treated with special shampoos, scalp psoriasis may require more potent treatments.
