With the τριχοριζόγραμμα we study the cycle of the hair, with the result that we reach the safe diagnosis of the cause of hair loss and then the appropriate treatment. With a digital camera recorded the total course during the course of treatment in order to better monitoring of the patient. The collection of a few hairs done with the help of forceps, and then examined the public microscope at a magnification of X10-Χ15, or with a special digital microscope and a computer.
In normal subjects are 80%-85% αναγενείς pockets, 1%-2% καταγενείς and 10%-20% τελογενείς. Although to normal people, we don't usually δυστροφικούς pockets a rate of 1% -2% is not considered a pathological finding. The anagen phase is the growth phase of the hair with intense activity of the enclave, has a duration of 2-6 years, and at this stage they are 85% of the hairs of the head. The catagen stage is the intermediate transitional stage where the prepare of probing for the shedding of the hair, it takes 2 weeks and is the 1% of the hair. The telogen phase is the resting phase of the hair with hibernate and then fall. Lasts 3-4 months. Dystrophic hairs found in various pathological situations such as in various infectious diseases, in trichotillomania, after chemotherapy, anticoagulants, in γυροειδή and androgenetic alopecia.
Φωτοτριχόγραμμα: What Is
The φωτοτριχόγραμμα is a modern non-invasive method for assessment of the parameters of the hair.
It is the most modern method of diagnosis and monitoring of the progress of non-ουλωτικών forms of alopecia, and can often replace the classic τριχοριζόγραμμα, a method which includes the "pull" of about 100 hairs and examination under a microscope.
One of the most specialized and advanced programs for φωτοτριχόγραμμα is the system of Hair Expert of the Digital Δερματοσκοπίου microDERM.
The Microderm Hair Expert has been designed for the analysis of changes in the growth cycle of the hair and can be used for all types of disorders of the hair, which is recognised by the changes in the following parameters:
- speed of development
- ratio – refresh hair
The technology of Photohairgramis mainly based on the growth rate (mm/day) and the ratio and hairs using 2 photos of the default region of the scalp were taken in 2 days.
For this reason, we cut the hair in the desired area (within 1 cm of the scalp) with the aim to attract the same area after 2 days, using the same magnification. These pictures, then, are evaluated through the specialized system for the analysis of hair on the computer.
In this way, the hair can be observed without disturbing the cycle of development, in contrast with the τριχόγραμμα where the hair is detached from the scalp.
When It Is Appropriate To The Examination Of The Φωτοτριχογράμματος;
The Photohairgram complements the clinical and laboratory control. Taking a personal and family history (autoimmune diseases, medications, recent surgeries, other diseases), testing for anemia, B12, folic acid and iron, as well as also hormon control women must be combined with the special examination.
The Φωτοτριχογράμματα Helps Us:
- in the investigation of the causes of alopecia, ensuring the correct diagnosis of the cause of hair loss
- in the treatment of various diseases of the scalp, choosing the most effective treatment for each case as well as
- in the monitoring of treatment, as we have the ability to record of the overall progress, the possibility of comparison and assessment at regular intervals.
More specifically, the hair transplant procedure includes the study of history in combination with the examination of the φωτοτριχογράμματος.
Still, it can be exploited in the study of androgenetic alopecia and diffuse alopecia, but also in the monitoring of therapy in hirsutism and δασυτριχισμό.
