Androgenetic alopecia is a form of non-scarring baldness that occurs during and after puberty and is characterized by follicular miniaturization and progressive hair loss. It can be judged by physical examination, trichoscopy and histopathologic examination.
1. Physical examination: The doctor will judge by gently pressing the patient’s front parietal and back occipital hairs and observing the density of hairs, whether there is obvious backward movement and other clinical manifestations.
2. Trichoscopy: In the early stage of the disease, when the clinical manifestations are not obvious. Doctors will use trichoscopy to observe the difference in the diameter and density of the hair on the top of the head and the back of the occipital part of the patient’s head, as well as the proportion of thinning hair follicles, in order to make a diagnosis.
3. Histopathological examination: For those with atypical symptoms, histopathological examination can be used to distinguish patients with atypical symptoms from other hair loss diseases. Scalp biopsy shows that the last hairs and anagen, cuirass and resting hairs increase in number.
It is recommended that patients with hair loss should consult a doctor in time for diagnosis by a professional doctor and follow the doctor’s instructions for treatment.
