         5 . The nozzle of  claim 3 , further comprising a holder extending between an open proximal end and an open distal end, the holder comprising:
 a proximal internal channel configured to receive the fluid transportation tube; and   a distal internal channel configured to receive the nozzle output tube.   
     
     
         6 . The nozzle of  claim 5 , wherein the holder further comprises a middle internal channel connecting the proximal internal channel with the distal internal channel. 
     
     
         7 . The nozzle of  claim 6 , wherein the middle internal channel is formed between a first wall and a second wall, wherein the first wall is configured as a stop for the fluid transportation tube. 
     
     
         8 . The nozzle of  claim 6 , wherein the middle internal channel has a diameter between 0.2 and 0.9 mm. 
     
     
         9 . The nozzle of  claim 5 , wherein the nozzle further comprises a nozzle output tube retainer surrounding at least a distal portion of the holder, the output tube retainer having a flange protruding beyond the open distal end of the holder and preventing the nozzle output tube to move out of the distal internal channel of the holder. 
     
     
         10 . A head for an aerosol container, the head comprising:
 a base configured to be coupled to the aerosol container, the base comprising an outlet portion;   a nozzle connected to the base;   a fluid transportation tube within the base that extends through the outlet portion and outside the base into the nozzle, wherein   the nozzle comprises a proximal region configured to receive the fluid transportation tube and a distal region including a nozzle output tube, wherein   the nozzle output tube comprises an output through hole having a diameter of 0.15 mm or less, and having a length between 2 and 6 mm.   
     
     
         11 . (canceled) 
     
     
         12 . The head of  claim 10 , wherein the nozzle is attached to the outlet portion of the base. 
     
     
         13 . The head of  claim 10 , wherein the fluid transportation tube is flexible. 
     
     
         14 . The head of  claim 10 , further comprising an elastically deformable actuator comprising:
 a lever arm; and   a coupling portion integrally formed with the lever arm and configured to be mounted around the fluid transportation tube, an aerosol valve exit and a portion of an aerosol valve activator;   wherein the coupling portion is configured such that when the lever arm is deformed by a user, the coupling portion actuates on the valve activator of the aerosol container.   
     
     
         15 . An aerosol dispenser comprising:
 a head; and   an aerosol container comprising a valve assembly, the valve assembly comprising a valve exit and a valve activator for selectively opening a passage from an inside of the aerosol container to the valve exit,   wherein the head comprises
 a base configured to be coupled to the aerosol container; 
 a nozzle connected to the base; 
 a fluid transportation tube within the base that extends from the valve exit through the outlet portion to outside the base and into the puzzle, wherein 
   the nozzle comprises a proximal region configured to receive the fluid transportation tube and a distal region including a nozzle output tube, wherein   the nozzle output tube comprises an output through hole having a diameter of 0.15 mm or less, and having a length between 2 and 6 mm. bard   
     
     
         16 . The aerosol dispenser of  claim 15 , wherein the nozzle output tube is made of polyetheretherketone.
