Device for the application of "extensions" (24) for hair (2), applicable following the orientation of the scales of keratin, engineered in a way that generates low specific pressure on the hair, in which the holding force is achieved thanks to the combination of the friction among the surfaces in contact (10,11), and the "fitting effect" created among the tip of the scales of the hair, with the calculated micro - roughness of the inner surfaces of the disposal; disposals light, simple, cheap, quickly applicable and removable by hand or with a special tool, having tiny size and low aesthetic impact, in version "ready-for-the-use" in various lengths, or in version "easy-cutting", built with bio - compatible material, flexible, coloured, perfumed, containing anti-bacteria substances, anti-virus substances, in the version "disposable", and in the version for animals.
