A vacuum cap for preventing baldness and revitalizing hair growth in case of hair fall comprises a cap made of an elastic material. The vacuum cap is turned upside down on the head (1). An adjustable band (1) is used to precisely adapt the vacuum cap on the head (4) of the wearer. Accessories shaped as a ring or an inflatable pipe (2) can be used alternatively for the same purpose. The physical principle by means of which hair growth is promoted is based on the fact that the application of a vacuum or of a negative pressure on the surface of the skin promotes blood circulation, so that the scalp is better irrigated. This has a very favourable effect on the hair roots and hair growth. Depending on the degree of elasticity of the material from which the vacuum cap is made, various means may be used to generate a negative pressure, from manual force to an electric vacuum pump. |
