"Grow in thicker/darker" is a myth. The reasons why hair seems to grow in thicker when you shave is because you cut off the thinner end of the hair, and the stem keeps growing out with a flat head.
Waxing doesn't make it thicker either, you pull out the entire hair, so a new hair grows back. You should just wax it if it's that bad. Buy some of your own and do it.
