What causes itchy head? These are the reasons

Itchy scalp is a condition that many people experience in their lives and seriously affects people's emotions. So what exactly causes people to experience itchy scalp? In fact, there are many reasons that can cause itchy scalp in life, the main one is because of the oily mud pollution caused by not washing the hair frequently.

1. What are the causes of itchy scalp?

There are many reasons for itchy scalp, but the main reason is that there are sebaceous glands at the root of each hair. The sebaceous glands need to secrete oil regularly, which causes the hair to be contaminated by oily sludge. If you do not wash your hair regularly, too much oil will accumulate at the roots of your hair. In addition, the sweat discharged from the sweat glands on the head is mixed with dust, dandruff and other dirt, and the sebaceous glands and sweat glands are blocked, making the excretion of sebum and sweat obstructed. The skin is irritated and the scalp will feel itchy.

Some people will find that their scalp is itchy and a lot of dandruff will fall off when they scratch it, and the more they scratch, the more itchy it becomes. This requires going to the hospital to determine whether you have tinea capitis. The early symptoms of this disease are itchy scalp and a lot of desquamation. This situation often occurs on many people's heads at the same time. At this time, it is most likely caused by tinea capitis infection. The itchy scalp caused by tinea capitis infection can only be well relieved after the disease is treated, otherwise there is no way to suppress it.

2. Fungal histopathological examination of patients with itchy scalp

Fungal histopathology is an important diagnostic method for deep fungal infections, and the identification of fungi in tissues marks the level of etiological diagnosis. Immunohistochemistry classifies fungi according to their antigenicity. The people who need to be examined are patients with symptoms of fungal infections such as keratitis and canaliculitis.

3. Dermatophyte microscopy for patients with itchy scalp

Dermatophyte microscopy is a method of finding hyphae and spores through direct microscopy for preliminary diagnosis. The culture method is to determine the bacterial species based on the characteristics of the colonies and their microscopic morphology and structure.

4. Differential diagnosis of scalp itching

Pay attention to distinguishing the causes of dandruff, scalp fungal infection or scalp allergy.

Diagnosis: There is usually a lot of dandruff, which is very small, like small white dots, densely packed, and the scalp is itchy and the hair is dry.

Fungal infections are usually accompanied by itching, occasionally hair odor, and swelling of the lymph nodes at the back of the neck. Fungi can cause hair to fall out, and excessive scratching of the nails can cause slight redness, swelling, pain, and ulcers with purulent discharge.
