Multi-tools platform for hair testing
Volume - Frizz - Motion
The system can be easily stored and deployed thanks to its foldable design
PLUG & PLAY
No special installation is needed - easy cabling and the system is ready to go
One of our aim at BOSSA NOVA Vision was to create an instrument that can accommodate a wide range of measurement capabilities in a package that is easy to use and easy to stow away.
The result is the Shuffle.
Crammed with years of optical R&D experience and feedback from cosmetic testers, the Shuffle consists of a collapsible frame that can be fitted with various attachments, allowing the user to measure a wide range of visual parameters using a single system. Those parameters includes :
- hair volume
- hair frizz
- hair motion
Laboratories looking to expand their research and cosmetic testing capabilities without breaking the bank or cluttering their space with bulky equipment now have a solution, a cosmetic Swiss-army knife.
As its core, the SHUFFLE is an imaging system dedicated to quickly and efficiently discriminate fly-away/frizz fibers from the bulk of hair swatches on an image using light transmission variations to evaluate hair density. Several attachments are available for a wide range of analysis.
The current attachments available are listed below :
TRIO / WIDE (default)
For 2D hair volume and frizz
This attachment can hold three hair swatches at the same time and enables simultaneous measurement of 2D bulk and fly-away-frizz on up to three tresses or one large tress, including time-lapse capability.
For 3D hair volume and frizz
This attachment consists of a software-controlled motor synchronized with the camera to image the entirety of a hair tress from 36 angles, reconstructing its shape at every angle, and providing a 3D reconstruction
HULA / HOP
For hair motion testing
This attachment consists of a calibrated motor which swings a tress back and forth, allowing the visual analysis of hair movement and hair perturbation, including time-lapse capabilities.
Using uniform back-light illumination, we can measure the transmission of the light through the hair swatch with a standard black and white image of the sample. For each pixel of the image, we measure the light transmitted.
If the transmission :
- is inferior to a defined threshold, this corresponds to a high-density area and we can define the pixel as part of the bulk
- is higher than the defined threshold, this is a low-density area and we can define the pixel as part of the fly-away / frizz
Using this analysis, and other standard image processing techniques, we are able to measure the following parameters :
TRIO / WIDE (default)
With this attachment, you can extract information about the change in hair volume and hair frizz of your swatches from a 2D analysis of up to 3 swatches simultaneously. Numerical data about the volume / frizz can be measured over the whole swatch or along the swatch vertical axis
This attachment allows for a similar frizz / volume analysis as the TRIO / WIDE attachment but uses a 3D reconstruction analysis instead of a simple 2D image analysis.

HULA / HOP
With motion, we can analyze similar parameters while the hair swatch is moving.
With the HULA, you can measure changes in volume and frizz during the movement of a hair swatch, but also the angle of the hair swatch axis and the damping effect. All those parameters can be measured with different speeds as the motor can move with a frequency between 0.7 and 2.5 Hz
With the HOP, you can compare the hair swatch characteristics (volume and frizz) before and after a user-defined perturbation (speed and duration)
