The type of alopecia is usually determined by clinical symptoms and relevant examinations.
1. Clinical symptoms: Alopecia areata usually includes seborrheic alopecia, patchy baldness, etc. Patients with seborrheic alopecia areata usually have progressive reduction of hair on the top of the forehead as the main symptom, while patients with patchy baldness will have sudden, limited and well-defined patchy alopecia symptoms. Therefore, according to the clinical symptoms, we can make a preliminary judgment on the type of hair loss.
2. Relevant examination: For the type of hair loss, if the diagnosis cannot be confirmed according to the clinical symptoms, you can cooperate with the doctor to carry out hair pulling test, hair microscope, dermatoscopy and other auxiliary examinations, so as to make a clear diagnosis of seborrheic alopecia, patchy baldness and other types of hair loss.
Patients with symptoms of hair loss are advised to go to a regular hospital in time and follow the doctor’s instructions for treatment, not blindly use medication.
