Frequently Asked Questions

Take the bristles cover with one hand, open-side up. With the other hand, grasp the brush by the handle (bristles-side down) and place it over the the bristles cover as shown in Fig. 3A. Then lower the brush (bristles-side down) straight down, holding the brush horizontally so that the cover lugs (14) on the brush are inserted into the locking guides (15) on the bristles cover (5). Then move the brush so that the arrow (17) on bristles cover (5) aligns with the "CLOSE" mark on the back side of the brush.

Fill the brush with solution. Remove the bristles cover and brush the hair so that the ends of the bristles touch the skin of the scalp in the areas where you wish to apply the solution.

Very important: for the liquid to be emitted from the ends of the bristles, you must press down lightly on the brush at the moment when the ends of the bristles touch the skin. In other words, the bristles’ ends must be pressed lightly onto the skin of the scalp for the liquid to be emitted.

The amount of liquid emitted onto the scalp by the brush bristles is regulated in two ways:

1) By the number of touches on a given area of the skin where the application of liquid is needed. In other words, you can brush the hair and guide the brush, touching a given area of the scalp just once, or you can brush the same area several times, thereby increasing the amount of solution applied to the skin several times.

2) By increasing the pressure of the bristles on the skin during brushing, more solution is emitted.

Shown in Figs. 4 and 6. A milliliter scale (18) is located on the back side of the brush. The maximum on the scale (and therefore maximum amount of liquid the brush can hold) is 60 ml, and it is divided into 1 ml increments. This scale allows the user to easily see and control the exact amount of the liquid inside the brush right before and after each application (hair brushing).

Shown in Figs. 4 and 6. The back of the brush has a milliliter scale (18) and incorporates a dosage slider (6), so that the user can conveniently see and control the amount of liquid dispensed during application. The dosage slider (6) has 2 indicators drawn on it: a "Top Green" indicator (7) and a "Low Red" indicator (8). The purpose of the green and red indicators is to allow the user to measure the exact dosage that needs to be applied to the scalp during application. The dosage slider (6) can be moved up and down by the user along the milliliter scale (18) so that the user can align the green indicator (7) with the liquid level (9) inside the brush before application of the liquid onto the scalp during hair brushing.

Each time prior to brushing the hair the user needs to hold the brush handle up and align the green indicator (7) with the liquid level (9). Then as the brush is used, the user needs to periodically check the liquid level (by holding the brush handle up) until the liquid level (9) reaches the red indicator (8).

The brush's task is to supply a proper amount of liquid contained within the brush to the scalp during hair brushing, while avoiding any wetting of the hair. Due to its construction features, the brush can not be filled with suspensions or emulsions. The brush is made of inert materials and can be filled with practically any liquid or solution intended for application to the scalp.

The brush should be kept at the temperature that is indicated in the instructions for the maintainment of the solution with which the brush is filled.

When the brush is filled with liquid it should be kept in a horizontal position with the bristles up and the bristles cover closed. Be careful! The cover seal (16) should be fitted firmly to the brush body (1)! Firm fitting of the cover seal to the brush body is necessary to ensure an airtight space around the bristles when the bristles cover (5) is closed, so that evaporation of the solution inside the brush is prevented.

The brush does not require special care. Nevertheless, occasionally washing the ends of the bristles with warm running water is recommended. If the brush is full of solution, before washing the ends of the bristles it is preferable (but not obligatory) to remove the solution to prevent the emission of solution from the ends of the bristles during washing, thus avoiding the unnecessary loss of solution.

The brush is intended for long-term use, and under correct care can work properly from several months to half a year and even longer. Nevertheless, depending on the thickness of the hair and the pressure placed upon the bristles in the process of using the brush, the term of its operational use can vary considerably.

The brush is made of inert materials, some of which are presently used in the pharmaceutical industry for the manufacture of containers that are used to hold liquid for medicinal preparations. The brush can be filled with practically any solution that is intended for application to the scalp. The brush body is made of a polycarbonate, the bristles and their roller-balls of stainless steel and the bristles membrane is made of silicone. Parts of the brush body are joined together and to the bristles membrane via ultrasonic welding, a type of welding that does not use adhesives. The bristles are inserted into the bristles membrane without the use of adhesives.

In the process of using the brush an insignificant amount of liquid in the form of separate drops may be emitted where the bristles are joined to the bristles membrane. This is not an indication that the brush is defective.
