ive got the same problem my hair is extremly dry and my split ends all awful from the years of straighting and highlighting etc, i always use without fail PAUL SMITH SHINE SPRAY, i buy it from my hairdressers, so pop to a hairdressers and theyll get it for you most prob, its about �12 for a fair sized bottle which last a good while! so good value for money, once ive washed my hair i give it a good spray before blow drying anf straighning the hair dressers say u only need like 1 or 2 sprays but my hairs soo bad i need a few, its fab and i wouldnt dream of straighning my hair with out it!!
