A trichogram is a microscopic procedure for examining the hair and its roots. It is used to diagnose the health of the hair and the causes of various hair and scalp problems, especially hair loss. By analyzing the hair roots and hair shafts under the microscope, a trichogram can provide detailed information about the growth phase of the hair, its density, and possible damage or disease to the hair follicles.
For a trichogram, 50 to 100 strands of hair are usually taken directly from the scalp to ensure that the roots can be examined. These hair samples are then analyzed under a microscope. The procedure allows the hair to be categorized into different growth phases: Anagen phase (growth phase), catagen phase (transition phase) and telogen phase (resting phase).
The analysis helps to identify anomalies in the hair growth cycle, such as an unusually high ratio of hairs in the resting phase, which could indicate increased hair loss. It can also be used to evaluate the effectiveness of hair loss treatment by comparing changes in hair growth before and after treatment.
In summary, the trichogram is an important diagnostic tool in dermatology and trichology that provides detailed insights into the condition and health of the hair and helps in the diagnosis and treatment of hair loss and other hair disorders.
