Overview
SAMBA Hair is a unique device to analyze hair shine (also called hair luster or hair gloss). It is extensively used in the cosmetic industry to substantiate claims and evaluate products efficacy – such as shampoo, conditioners, shine sprays, etc. – on any straight hair.
SAMBA Hair comes as a turn-key system. It includes an imaging sensor head, an in-vitro enclosure with a sliding cylinder, as well as a computer with dedicated and user-friendly software. The hair samples are positioned on a cylindrical mount that slides inside the instrument.
The system also allows in-vivo measurements using a rotating arm positioned on the side of the imaging sensor head.
A complete analysis of the gloss characteristics of your hair tress is delivered in seconds. It includes :
- Specular and Diffused images obtained with our polarization-imaging sensor
- Angular profiles of Specular, Diffused and Chroma
- Numerical data : Luster, light intensity, shine bandwidth, etc.
All those data can be quickly compared and exported for reports, presentations or post processing.
Principle
SAMBA Hair system acquires successively 2 images of parallel and crossed polarization state. This allows the decomposition of the image seen by a conventional camera or the eye into 2 images: specular and diffused.
The specular image is formed only by the light reflected by the hair surfaces (front-side reflection and back-side reflection). This image contains the shine and chroma information.
The diffused image is formed only by the scattered light coming from the inside of the hair. This image contains the color information.
Assuming that the surface reflection – the shine – does not contain color information, virtual profiles of shine and chroma are calculated from the specular image using a color based algorithm. The shine profile is black & white, while the chroma profile contains all color information. The light scattered by hair fiber can then be decomposed into 3 components: Shine, Chroma and Diffuse.

Hair Color
Those images gives us measurements of several parameters including light intensity, angular profiles, color distribution. Several formulas for hair luster including Reich-Robbins, TRI coefficient and our own BNT coefficient are directly used to characterize the luster of your hair sample.
