I haven’t watched much, as I can’t bear Dennis (or his bliddy mom)
His voice grates, and he seems to have trouble standing still. He always uses models with thick, coloured/bleached course hair. It’s easy for a hairdresser to get a ginormous bouncy blow dry on that type of hair, no matter what product is used. As Merryone said, those styles look ridiculous (very American!) and certainly can’t be achieved on thin fine hair. A hairdressing colleague of mine in the 70s/80s had a client who she always said has got ‘two hairs and a nit’ and expected to leave the salon looking like Farrah Fawcett Majors!
