Each patient must be approached individually. The patient is advised to wash her hair on the day of her evaluation. During the exam, the doctor observes the appearance of the patient’s hair- color, texture, thickness, density. Hair loss is usually divided into two main groups: diffuse or localized. If diffuse, such as with female pattern baldness, the degree of hair loss is defined. Nowadays, most commonly, the Ludwig scale is used for female pattern hair loss. If localized, areas of hair loss should be further examined for the presence of any significant redness, patches of different colors, scars or scaliness of the scalp, possibly indicating some type of disease of the skin. In addition, the appearance of any existing hairs are also noted.
After the physical examination, more detailed tests are done.
