The use of scalp cooling is, evidently, the best method to avoid alopecia, the side effect of the major part of the chemotherapy treatments.

The scalp cooling system through the circulation of extremely cold air by a thermal cap with internal fins that guarantee turbulent flow (patented by Fabinject) offers a superior response to the traditional methods of cooling.


Several white papers and patents published around the world since the 1970s show that scalp cooling helps in reducing hair loss (alopecia); an effect that is very common and expected when using some chemotherapeutic drugs.

In the beginning, plastic caps were used to place crushed ice.

Subsequently gel (in liquid form) caps (1) were created. This gel, which is malleable and difficult to freeze, is a relatively effective method of cooling, since it is kept at extremely low temperatures (common freezers are not able to fulfill this function), and are changed from time to time as a result of their heating. This method, in particular, demands much discipline and attention from the medical staff and the patient himself. Thus, several studies prove the poor performance in most of the cases in which this method is chosen.

Then came the equipment that cooled a circulant liquid (2). Such cooled liquid would circulate throughout the cap attached to the patient head, leading to the cooling of it. Because it is contact cooling through a silicone coil, this method does not fit into 100% of the scalp for most patients. Complaints about the existence of bald spots in the midst of hair maintenance are very common. In addition to the fact that the cap, to maintain the coupling, should have a perfect fit, something little achieved throughout the treatment.

These caps are also relatively heavy and as the treatment demands a long period of coupling, patients often complain.

In the two cases cited above, gel cap (1) and circulating liquid equipment (2), the caps have low durability, having to be exchanged in short periods of time, thus increasing costs.

To overcome the above-mentioned problems, a scalp cooling system was developed through cold air in a flexible cap, which was not very successful in the market due to the fact that the air temperature was not cold enough and by keeping areas with air at different temperatures. Some areas were hotter than others.
