How is seborrheic alopecia diagnosed

Seborrheic alopecia can be clearly diagnosed by the doctor through questioning, visual examination, hair pulling test and dermoscopy.
1. Consultation: Gradual thinning and loss of hair, receding hairline, increased dandruff, pimples and other manifestations can be seen in the dermatology department of the hospital. The doctor will ask the patient’s age, family history, and information about hair loss to find out whether it is hereditary or not, and also assess the severity of hair loss.
2. Visual examination: The doctor will observe the site, range, distribution and characteristics of the patient’s hair loss through the naked eye.
3. Hair pulling test: Do not wash your hair within 5 days before the examination. After cleaning your hands, the doctor will pull up about 50~60 hairs with his fingers and observe the number of hairs pulled down, which will basically make a preliminary diagnosis.
4. Dermoscopy: Through dermoscopy, enlarged, high-definition localized images of skin damage can be observed, and the severity of hair loss can be assessed.
It is recommended to go to the dermatology department of the hospital for examination if you have more hair loss. Through the relevant examination, it is convenient for the doctor to identify the disease, and it can also assess the severity of hair loss.
