To determine hair loss, you can look at the number of hairs that fall out every day, the density of the hairs, and the accompanying symptoms.
1. Number of hair loss per day: Hair has its own growth cycle and is in a dynamic balance between new hairs and hair loss every day. When the number of hair loss exceeds 100 per day, it will be regarded as pathologic alopecia.
2. Hair density: if hair loss continues for a period of time, for women who find that their braids are thinner than before, or for men who find that their hairline is wider than before, and their scalp is exposed, etc., it is generally a pathologic form of alopecia areata.
3. Accompanying symptoms: if the scalp appears obvious itching, hair greasy faster. Or when the hair is dry, brittle, yellow and other symptoms, it should be taken seriously.
Patients who have a significant reduction in hair should seek timely medical attention, improve relevant examinations and standardize treatment.
