title: Usefulness of TrichoScan professional in the evaluation of hair loss in females. Report of 180 cases.
abstract: BACKGROUND
  TrichoScan Professional is a computerized program used for digital measurement of hair growth and hair loss. The aim of our study was to undertake an evaluation with TrichoScan Professional of female patients consulting at our hospitals for hair loss. The purpose of our study was to determine whether TrichoScan was able to identify differences in hair parameters that would correlate with the pattern of alopecia or according to the age of the patients evaluated.
  
  
  METHODS
  One hundred-eighty women that consulted consecutively for loss of hair were included. Patients were aged between 8 and 85 years (mean age 36 years). Data including age, the number of hairs, hair density per square centimetre, anagen and telogen percentage and percentage of terminal and miniaturized hair were analysed.
  
  
  RESULTS
  Results observed with TrichoScan were as below: number of hairs (mean 154.9; range 34-316). Hair density per square centimetre (mean 239; range 52-486). Hair in anagen phase (mean 62.4%; range 9-93%). Hair in telogen phase (mean 37.4%; range 7-91%). Terminal hair (mean 95.2%; range 82-100%). Vellus hair (mean 4.7%; range 0-17%). Pearson's correlation test was used to measure the strength of the association of age with the rest of parameters. The statistical analysis showed a significant correlation between age and both the number of hairs and the hair density per square centimetre. However, no significant correlation between age and rest of the parameters was observed.
  
  
  CONCLUSIONS
  TrichoScan Professional may help to quantify hair density and in our sample, this was the only parameter showing a significant decrease according to age in various types of alopecia affecting the females.
