H2H Matching®

Invented and developed at TrichoLAB, the H2H (Hair-to-Hair) Matching technology is an alternative approach to phototrichogram (clipped) and trichoscopy (non-clipped) image analysis. Based on a Follicular Map concept and matching of baseline and follow-up images on a hair-by-hair level, it achieves unprecedented measurement sensitivity and precision. Consequently, the effectiveness of medication can be assessed in clinical trials with a lower number of subjects compared to a traditional hair count study (or the same subject sample achieving better accuracy of the result). H2H Matching also gives insight into the history of individual hair throughout the treatment, allowing for a pin-down analysis on the detail level that has not been possible before.


The phototrichogram (PTG) is the gold standard in hair treatment efficacy measurement. It is performed with a high-resolution microscopic image of a scalp spot with hair clipped to ca. 1mm. An analysis of PTG images allows for the determination of the hair count, the hair shaft diameters and correlations of these parameters. To measure hair growth and anagen/telogen rates, a few days delay is allowed between clipping and imaging for hair regrowth. 

Virtual Tattoo®

Virtual Tattoo® is a patent pending technology invented and developed at TrichoLAB. It helps to ensure that the SAME test spot is used in all examinations following the baseline. The use of augmented reality simulates tattoo marks for the test spot on the computer screen when scanning the scalp during follow-up examination. The technology also practically eliminates the risk of mistaking another spot on the scalp during follow-up examination and ensures the use of exactly the same area of measurement.


TrichoLAB offers a complete set of tools for precision trichoscopy - a version of quantitative trichoscopy optimised to achieve the top hair treatment efficacy measurement accuracy in terms of hair count, hair shaft diameters and follicular unit distributions. The hair does not need to be clipped for trichoscopy, making the examination truly non-invasive and easily accepted by all subjects. Supported by Artificial Intelligence, automatic and manually assisted image processing in the central TrichoLAB processing workflow, combined with enhanced data quality assurance, trichoscopy ensures the best possible measurement accuracy. The complete examination and project management software environment ensures strict protocol adherence, data consistency and centralised management.

Clinical Photography

Clinical photography has always been an integral component of hair treatment efficacy studies as it provides results in closest relation to patient perception. TrichoLAB studio includes the FotoFinder portrait stand optimized for scalp photography, with a high resolution digital camera, polarised flash light system and a set of head holders to take perfectly reproducible images of the following areas of a subject’s scalp:

  • frontal
  • vertex
  • temporal
  • parietal
  • occipital



  • Hair density
  • Hair diameter
  • Hair distribution
  • Anagen/Telogen rate
