What is the Difference Between Scalp Psoriasis and Dandruff?

 

If your head feels itchy and you notice white flakes in your hair, a doctor can figure out if it's just regular dandruff or something more serious like psoriasis. Psoriasis is a condition that makes your skin get red and scaly patches. So, its important to know the difference between scalp psoriasis and dandruff.

Although both can lead to a flaky scalp, they have some differences in how they appear. Once the doctor figures out what's going on, they can suggest the right treatment to help you feel better.

 

Dandruff

Ever heard of dandruff? It's like those small white or gray flakes that pop up on your hair and end up on your clothes. However, dandruff is basically when your scalp gets a bit grumpy and starts shedding dead skin cells like crazy. It's super common and even has a fancy scientific name - pityriasis simplex capillaritis.

 

So, here's what happens, your scalp has this natural oil that it produces, which is totally normal. But sometimes, this pesky yeast-like thing called Malassezia overgrows on your head. These flakes eat natural scalp oil, but the downside is they can make your skin all irritated and flaky. That's when you start seeing those dandruff flakes. 

 

Scalp Psoriasis

Scalp psoriasis is a condition where the immune system goes a bit haywire. Instead of working normally, it makes skin cells grow super fast. This speedy growth creates thick, red patches on the scalp that get covered in silver-like scales. Even though psoriasis can show up on different parts of the body, when it happens on the scalp, it's named scalp psoriasis. Unlike dandruff, which happens because of too much fungus, scalp psoriasis happens because the immune system acts up.

Imagine your immune system like a security guard for your body. Normally, it helps keep you safe by fighting off bad stuff like germs. But in scalp psoriasis, it starts acting a little confused. Instead of doing its job well, it tells your skin cells to grow too fast. This causes those thick and red patches to form on your head, covered in those silvery scales.

How Do The Symptoms Of Dandruff And Scalp Psoriasis Differ?

The symptoms of dandruff and scalp psoriasis have some differences that can help tell them apart. 

 

Dandruff:

• Shows up as small white or yellow flakes in your hair and clothes.


• Can make your scalp itch, but usually not very strong.


• Generally simpler and less severe.

 

Scalp Psoriasis:

• Patches on your scalp might look like scales, not just flakes.


• Mild cases can have silvery or powdery patches that come off in bits.


• Can become red, painful, or sore if it gets worse.


• Might spread to your forehead, skin around ears, or back of the neck.


• Can show up on other body parts like elbows, knees, or back.
