Um, depends on what you do. I'm natural now but perms weren't too pricey (like $5 in the box, $10-$20 for a doobie every other week) -- I just get a lot of hair products.
I also wear weaves and wear expensive ass hair, too lazy/don't know how to wash it so I discard it after I take it out. I probably should stop. Braids/twists as well.
