         8 . The brush of  claim 1 , wherein an outer edge of the cylinder opening is attached to an inner wall of the housing. 
     
     
         9 . The brush of  claim 1 , wherein the housing comprises a lower housing and an upper housing assembled together around the thermal insulation cylinder and a back housing forming the end of the housing, wherein the air inlet is foamed in the back housing. 
     
     
         10 . The brush of  claim 9 , further comprising a reticular sleeve element disposed between the back housing and the thermal insulation cylinder. 
     
     
         11 . A method of making a brush, comprising:
 providing housing comprising:
 a lower housing having an air discharge portion formed therein; and 
 an upper housing; and 
   assembling a thermal insulation cylinder between the lower housing and the upper housing, the thermal insulation cylinder having an inner diameter gradually decreasing from a cylinder opening to an outlet;
 wherein the outlet is aligned with the air discharge portion; and 
 wherein the cylinder opening faces an air inlet formed at an end of the housing; 
   assembling and an air guiding mechanism between the lower housing and the upper housing; and   providing a power source to the air guiding mechanism.   
     
     
         12 . The method of  claim 11 , further comprising arranging a heating element inside the thermal insulation cylinder. 
     
     
         13 . The method of  claim 12 , wherein the heating element is a quartz tube and is arranged inside the thermal insulation cylinder such that light emitted from the quartz tube transmits through the air discharge portion. 
     
     
         14 . The method of  claim 11 , further comprising:
 providing an air combing head comprising:
 a base; 
 a plurality of air holes formed through the base; and 
 a plurality of brush teeth fixedly disposed on the base; 
   removably attaching the base to the lower housing at the air discharge portion,
 wherein each air hole is arranged on the base to correspond with each of the air outlets formed in the air discharge portion. 
   
     
     
         15 . The method of  claim 11 , further comprising attaching a release mechanism to the lower housing, the release mechanism comprising:
