       10 . A hair styling apparatus comprising a pair of heated styling heads arranged for contact styling of hair, and a pair of cooling heads defining a pair of contact cooling surfaces, wherein said cooling heads are disposed immediately adjacent said heated styling heads and are arranged for compressively engaging hair upon exit of said hair from said contact styling surface for contact cooling of said hair, and a heat sinking mass is attached to a cooling head for dissipating heat away from said contact cooling surface. 
   
   
       11 . A hair styling apparatus according to  claim 10 , wherein said heat sinking mass is non-metallic and comprises a slab of rock-like substances with a high heat mass. 
   
   
       12 . A hair styling apparatus according to  claim 11 , wherein a metallic heat sink is attached to said non-metallic heat sinking mass for dissipating heat away from said non-metallic heat sinking mass. 
   
   
       13 . A hair styling apparatus according to  claim 12 , further comprising a magnet, wherein said magnet is disposed so that magnetic force appearing on said styling surface has a magnetic density of between 300-20,000 Gauss. 
   
   
       14 . A hair styling apparatus according to  claim 13 , wherein said magnetic density is about 4,000 Gauss. 
   
   
       15 . A hair styling apparatus according to  claim 14 , wherein said magnet comprises a permanent magnet slab, said contact styling surface being magnetic permeable, said magnet slab being disposed underneath said styling surface so that magnetic field of said magnet slab is distributed on said contact styling surface. 
   
   
       16 . A hair styling apparatus according to  claim 15 , wherein said permanent magnet slab, said heating means and said contact styling surface forms a sub-assembly which is resiliently movable relative to the main housing of said styling apparatus. 
   
   
       17 . A hair styling apparatus according to  claim 12 , wherein said non-metallic heat sinking mass and said metallic heat sink are formed as a module and resiliently supported on a housing of said hair styling apparatus. 
   
   
       18 . A hair styling apparatus according to  claim 17 , wherein said pair of heated styling heads and said pair of cooling heads are side-by-side arranged for hair straightening. 
   
   
       19 . A hair styling apparatus according to  claim 18 , wherein said pair of cooling heads are arranged for cold shocking hair upon exit of heated hair from said pair of styling heads. 
   
   
       20 . A hair styling apparatus according to  claim 18 , wherein said pair of cooling heads is pivotally mounted such that the pair of contact cooling surfaces can be flipped in for contact cooling and flipped out for non-contact with hair. 
   
   
       21 . A hair styling apparatus according to  claim 18 , wherein an elongate air-gap is disposed intermediate a heated styling head and an adjacent cooling head for insulating said cooling head from said heated styling head. 
   
   
       22 . A hair styling apparatus according to  claim 18 , wherein said permanent magnet slab, said heating means and said contact styling surface forms a sub-assembly which is resiliently movable relative to the main housing of said styling apparatus. 
   
   
       23 . A hair styling apparatus according to  claim 11 , wherein said rock like substance is selected from the group comprising granite, marble, quartz and mica.
