There are different reasons/causes for scalp eczema.
In the first group, the eczema happens no matter what we do. There are still several skin disorders, and hair eczema whose causes are unknown to this day. Some of these hair eczema starts as eczema and might turn into something else later.
There is also hair eczema that occurs due to the use of external hair products. This type is fairly easy to treat, and the symptoms are often similar in this type. Rash, scabbing, burning, and itching are some of the most common symptoms. If we identify the cause of eczema in this type, we can find the correct treatment. In a short time, we can manage the use of shampoos, lotions, and other hair care products, and cure the eczema. And yet, the first type is difficult to treat because the diagnosis is hard, and we sometimes need to do a biopsy.
Generally, the trash, burning, and the stinging give the same look. Therefore, it is important for us to have a systemic examination. There is the type of hair eczema, seborrheic dermatitis, and it is hard to distinguish it from psoriasis. We often distinguish between these two illnesses via biopsy. It is like a must and yet, when we examine a patient, and the dermatological examination points to the special symptoms of psoriasis, there may be no need for carrying out a biopsy. And we can start the treatment shortly.
Often patients care about the parts of their bodies that they matter to them the most, and notice the symptoms in those areas. For instance, if a patient has hair eczema but also eczema on the body, they might often pay no mind to the eczema on their body, and therefore the systemic examination is very essential.
