5. When do you need medical treatment?
Consult your veterinarian immediately if you experience any of the following: skin redness/crusting (ignored by 87% of users), patchy hair loss (possibly ringworm), or abnormal weight changes (possibly hypothyroidism or Cushing's disease). The latest research shows that the recovery rate of cases that seek medical treatment in time is 3.2 times higher than that of cases that are handled on their own.
Through scientific maintenance, 90% of hair loss problems can be improved within 6 weeks. It is recommended to establish a "Hair Health File" and take regular photos to record the changes in the hair removal area, which has important reference value for diagnosis.
