Seborrheic Dermatitis VS Scalp Psoriasis

What is the difference between Seborrheic Dermatitis and Scalp Psoriasis?

Seborrheic Dermatitis vs Scalp PsoriasisSeborrheic Dermatitis and Scalp Psoriasis are common scalp conditions that have very similar signs and symptoms. That’s why most of the time people tend to interchange the two. They are both seen on the scalp with red and scaly patches. Both are also non-contagious. It’s true that they have very similar appearance however; there are certain characteristics that make them differ.

But before discussing the difference between the two, here are the signs and symptoms for Seborrheic Dermatitis and Scalp Psoriasis:

Seborrheic Dermatitis

  • Oily or greasy red patches on the scalp.
  • Forms yellow or white scales
  • Crusted scales are attached to the hair but can be easily removed
  • Can be very itchy
  • Your scalp can be sore
  • It can also affect the parts of the body where the oil glands are very active like the chest and back areas

Scalp Psoriasis

  • Red patches on the scalp
  • Forms silvery-white scales
  • The crusted scales may bleed when removed
  • Very Itchy and the scalp is also sore
  • The red patches can spread beyond the hairline
  • Psoriasis patches can be found in other parts of the body like the elbow and knees

With the given symptoms above you can notice some differences between the two.

To sum it up here are the main differences between Seborrheic Dermatitis and Scalp Psoriasis:

  • Pay attention to the size, color and where the scales are. The size of the scales formed if you have Sebhorreic Dermatitis is smaller and thinner compared to the scales formed by Scalp Psoriasis. The color of the scales associated with Seborrheic Dermatitis is usually yellow but with Scalp Psoriasis the scales have a silvery-white color. And the affected area for Seborrheic Dermatitis usually is limited with in the hairline while Scalp Psoriasis tends to spread behind the ears, back of the neck and the forehead.
  • Aside from the scalp, one major symptom if you have Scalp Psoriasis is if you have other Psoriasis patches on your body specifically on the elbow, knees, and hands. While for Seborrheic Dermatitis the common areas are the back and the chest.
  • It is easier to remove the scales of Seborrehic Dermatitis than Scalp Psoriasis because the scales are normally attached on the hair follicle while for Scalp Psoriasis they are attached on the scalp. That’s why when you remove them they tend to bleed.

Still, it is highly recommended to seek a dermatologist’s advice. The expert will definitely know what skin condition you have as well as prescribe the proper treatment for your condition.
