I am going to go ahead and say that it will be successful.  (I am a dude and will not buy one.)<p>Reasons are that regular hair dryers are just not very good. They are not pleasant to use.<p>And there are millions of women, primarily, who spend probably $2500 or more a year on cosmetics&#x2F;makeup&#x2F;hair. So a $400 one time expense for something that will last for years, doesn&#x27;t seem that bad.
