Hair?!?

De
So for about 3 years I didn't want to cut my hair at all. I was doing all kinds of hair masks and oil treatments because I wanted it to grow long without trimming it. Well sure enough within 2 1/2 years my hair grew from my shoulders down to my butt. Now everybody in my family expects me to never cut my hair, especially my dad because it is part of his religion for the women not to cut their hair. Now I really want to cut like 3 inches off because of the dead ends, but I don't have the money to go and get it done without my mom taking me. I don't really know how to go about asking her.
