Any hair loss requires an in-depth assessment to determine the cause and therefore be able to offer an adequate treatment. This assessment can include:
- Interrogation
On your first appointment, a questionnaire will need to be filled before your consultation.
- Blood test
A blood test is essential to check, among other things, the deficiencies that can cause hair loss: iron, zinc, vitamin B12 and folic acid. A thyroid as well as a hormonal checkup.
- Trichoscopy
Trichoscopy or scalp dermatoscopy consists of analyzing the hair and scalp under an epiluminescence microscope. It is a non-invasive diagnostic tool, very useful for the diagnosis and monitoring of hair and scalp disorders.
- Tensile test
A bundle of about 50 hairs is grasped between the thumb, index and middle fingers near the base. The hair is firmly pulled back. The test is positive when more than 10% of the seized hairs (on average more than six hairs) can be removed. This test is performed at 9 separate points on the scalp.
- Trichogram
The trichogram consists of taking about thirty hairs in 2 specific areas of the scalp to study the bulbs, the diameter of the hair and their quality under the microscope.
This test can help find the cause of some hair loss.
It also makes it always possible to quantify the extent of the fall and to monitor the effectiveness of a treatment.
- Phototrichogram
Phototrichograms are automatic scanned imaging techniques used to examine the characteristics of hair loss for diagnostic and monitoring purposes.
- Biopsy
Scalp biopsy is an essential tool in the diagnosis of scarred and selected forms of non-scarred alopecia. It consists of taking a small piece of skin from the scalp under local anesthesia measuring 4 mm in diameter and 5 mm deep to visualize under a microscope the hair, their roots but also all the hair appendages.
