Overview

When designing a hair conditioning product or styling device, you need to know how well it is preventing hair breakage from repeated combing or brushing. Or when you formulate any product designed to improve specific aesthetic or mechanical properties (shine, friction, smoothness, frizz, etc.), you want to understand how repeated combing will affect the hair properties. 

In any of those cases, an automated hair combing test will be able to help you assess and quantify hair breakage, abrasion or product resilience for your hair care claims. 

At BOSSA NOVA Vision, we developed the SIRTAKI – an automated combing rig – to provide hair product manufacturers with a state-of-the art device to simplify the measurement process.

The SIRTAKI combing machine provides an adjustable combing rate – from 1 to 2.3 Hz with a steady, even torque – for up to 6 swatches at a time. It can be left to run for hours on its own without supervision. A back-lit tray under the combing mechanism can be slid open to identify and analyze the collected broken hair fibers.

Principle

The instrument is operated using a simple interface on the controller on the side of the system. The user can start or stop the combing rotation at will, and adjust the rotation speed from 10 to 35 rpm. The equivalent combing frequency can then range from 40 to 140 combing per minute. An emergency STOP button is present (in red) to stop the combing in case of a hair swatch being stuck or tangled. A RPM (Rotation Per Minute) indicator displays the speed of the combing rotation.

Each slot is fitted with up to 4 evenly spaced and easily replaced combs. The swatch mounts are attached to a height-adjustable bar for maximum adaptability. Hair swatches can be easily removed and attached with the thumb screws mechanisms. We can also provide brushes specifically designed for the SIRTAKI. Other combing or brushing apparatus can be adapted on-demand.

Automated SIRTAKI

The SIRTAKI can come with an automated hair fiber counting option – instead of manual – in which case, the detection and counting of broken hair  fibers is done automatically through an imaging system that periodically inspect the trays.

A software developed by BOSSA NOVA Vision will then control the tray system collecting the broken fibers as well as the camera inspecting them. The user has the possibility to decide the frequency at which he wants the trays to be inspected so that a time evolution of the breakage rate of each individual hair swatch can be measured.
