A hand held imaging device for measuring characteristics of hair and scalp, comprising a housing with a high magnification optic for obtaining magnified images of surface characteristics of hair fibres, said high magnification optic comprising a first lens and a first light source, and a low magnification optic for obtaining magnified images of the scalp and hair, said low magnification optic comprising a second lens and a second light source, wherein the high magnification optic has a fixed focal length and a slot for locating hair fibres in frame such that the hair fibres are in focus and wherein the device further comprises a viewing means, selected from an integral viewing means, an external viewing means and a combination thereof.

Some embodiments are directed to a system for assessment of hair condition, including an analysis unit configured to at least obtain a first follicular map representing a first plurality of hair root positions in a first videodermoscopy image. The analysis unit is arranged to analyze at least the first follicular map to determine an analysis result suitable for assessment of hair condition. The system can be arranged to perform an image processing algorithm on a first videodermoscopy image to obtain the first follicular map.

Comprehensive systems and methods for managing hair loss are provided which enable an individual experiencing hair loss, and/or the person consulting him or her, to manage it and to determine and efficiently plan any appropriate treatment options. Management of hair loss may comprise quantifying hair loss, determining what hair growth stimulation product or treatment to adopt and the best timing for such products and/or treatments, and allowing to track and manage any progress of the selected hair growth stimulation product or treatment.

A hair feature analysis method and system are provided. The hair feature analysis method includes the steps of capturing high magnification and low magnification images of a scalp area and performing preprocessing on these images. The preprocessed high magnification and low magnification images are then input into an artificial intelligence model to simultaneously detect hair follicles and calculate hair widths in the scalp area. Hair characteristics are then calculated based on the analyzed high magnification and low magnification images. The artificial intelligence model can be an R-CNN model or a variant thereof.

The present invention relates to a Method for Measuring the surface of the scalp for assessing bald areas (recipient areas), areas with thinning hair, and areas with thick hair (donor areas), using the counting of micropolygons in 3D models and/or 3D meshes created by technologies that generate full-scale 3D models. Additionally, the present invention pertains to a Method for Mapping the surface of the scalp to measure bald areas (recipient areas), areas with thinning hair, and areas with thick hair (donor areas). The invention also relates to a corresponding system and a computer program for these purposes

The invention relates to a face imaging device comprising a casing defining an opening for a face of a person to be imaged, wherein in the interior of the casing light sources and reflectors are arranged. The invention further relates to a method for taking images of a face of a person using the device and to the use of the device.

There is a system for one or more of a user hair health and scalp health determination of a user, the system comprising: a hair analysis assembly, configured to: obtain a set of user head images of the user; analyze the set of user head images to detect one or more head characteristics; calculate a set of user head health scores, based on the detected one or more head characteristics. The system may further output the user head health score.

A face imaging device incudes a casing defining an interior space and an opening, at least one light source, at least one sensor configured to detect real-time face orientation, at least one camera, at least one display configured to display symbology associated with face orientation, and a controller configured to display fixed symbology indicating a desired face orientation, display movable symbology indicating a real-time orientation of the face to be imaged, and image the face when the movable symbology aligns with the fixed symbology.
