i don't trust my hair with a hairstylist! i've had too many bad experiences, so i generally trim my hair myself, which is free
(except for my recent chop, i donated my hair.)
but i totally know what you mean about the expensive products!!! its hard to justify buying such expensive products when you can buy cheap stuff at the store...but the quality is cheap too. some good company should develop a cheaper line that they sell all over... they would make a lot i bet!!
