Seborrheic dermatitis of the scalp is sometimes hard to differentiate from psoriasis.
With seborrheic dermatitis, there is more redness, more angry-looking skin, and more oiliness to the skin. There can be a variety of colors noted in seborrheic dermatitis, including bits of yellow or red-colored skin. That type of coloring isn’t seen so much in psoriasis. Psoriasis tends to be characterized by flaky, white skin.
Hair can sometimes get stuck into a seborrheic dermatitis rash. That can also happen in psoriasis, but in that case, it tends to be white flakey skin attached to the hair rather than red or yellow skin.
Psoriasis can be seen around the ears, but so can seborrheic dermatitis. Seborrheic dermatitis can also be in patches around the scalp area. It’s not uncommon at all for me to find someone who has had dandruff for a while, and then it turned into seborrheic dermatitis.
Seborrheic dermatitis can be a very annoying condition. People can get quite distressed with chronic cases. If you find yourself in that situation, look at my videos on the topic. I discuss natural treatments and dietary interventions for seborrheic dermatitis on my YouTube channel.
