5. Psoriasis
Another relatively common problem of the immune system is psoriasis. But in this case, it is not an allergic reaction. Instead, the main trigger of psoriasis is acute and chronic stress, which can be either physical or emotional. In psoriasis, patients may experience severe changes in the color of the skin. The skin turns scaly and starts leaving flakes as discreet areas of the skin begin to peel off. One of the most common areas of psoriasis lesions include the scalp and areas around the scalp, but it may also appear in many other places throughout the body. This is not a severe or life-threatening disease, but if patients do nothing about it, the compromised area will spread.
