Trichoscan Analysis

Quantitative methods for the analysis of human hair growth.

TrichoScan Analysis

TrichoScan is a advance German patented technique to measure hair loss.  It is a software-based method to analyze human hair. The main purpose of this process is to identify the root cause problem (like deficiency, disorders, infections etc.),  It calculates responses to treatment in patients with pattern alopecia, enables a precise follow up of hair densities(n/cm² ), and  hair diameter (µm), hair growth rate (mm/day), or anagen/telogen ratio. For this purpose, digital images are taken from the scalp with a specially developed camera-optics system.  

TrichoScan software is then used to automatically calculate important parameters of hair growth, such as hair density or thickness from the images. It can be used for studying AGA or other forms of diffuse hair loss, and it can be adopted to study the effect of drugs or laser treatment on Hypertrichosis or hirsutism.

Procedure:

The procedure was carried out as per the TrichoScan user manual. All the subjects were asked to wash their hair with a regular shampoo 2 days before the procedure. They were also instructed to avoid using hair oils or hair products.

Selection of the optimal measurement site for TrichoScan

Representative area of the scalp was prepared for the procedure

Female

The site for both female controls and study cases was same, i.e., mid-scalp region; 1 cm lateral to the mid-line hair partition between highest points of pinnae of both ears, so that the hairs in close vicinity can be combed over the clipped area.

Male

In controls and AGA grade III (with only bi-temporal recession, no vertex thinning, no thinning over the crown), the site was an area 1 cm behind the frontal hairline in temporal region on either side, whereas in the other cases it was a transitional area of hair loss between normal hair and balding area, i.e., the vertex in cases presenting with vertex thinning or the crown in cases with FPHL.

Suitable for Trichoscan:

As an automated image analysis tool, the TrichoScan results strongly depend on the image quality. It was made sure that all the images were optimum with the following features:    

Kindly follow the below mentioned guidelines (strictly)

Clean and sharp images with no hair dye remnants,

Wet hairs without presence of larger air bubbles,

No long hairs passing into the measurement site from outside,

Hairs are evenly clipped and dark due to the hair dye.

Hairs have a minimum length of approximately 0.5 mm to allow detection.
