yeah, i have at the salon, and it is good. i also have a razor at home and do it myself sometimes.
my hair used to be really thick, and now it is.. not so thick
it does make your ends feel abit shoddy, BUT i love the way it makes your hair look when it grows abit, and if you use lots of intensive conditioner or hot oils for hair ends (i am lazy so i cant be arsed) i imagine it would get rid of the grotty feeling.
