Wet hair is more sensitive to heat and more susceptible to break off more quickly making it harder to style.  B.R.U.S.H. gives you better control over the heat and styling in dry hair. B.R.U.S.H. was developed with the professional hairdresser in mind making sure that daily use was not easy and quick but also maintained the integrity of the hair.  You can use B.R.U.S.H. every day, not just when you wash your hair.
