I cut my husband's hair all by myself! I am quite proud of this fact. He hasn't seen a barber for over three years.
We purchased a set of $30 clippers at Target (love that store...)
His hair grows quickly, but unevenly, so he needs it clipped every 4-5 weeks. At $10/cut and 12 barber visits per year, we've probably saved $360 over the past three years just by cutting his hair on the back porch or in the basement. We spread out a big sheet to make cleaning up easier.
To us, it is totally worth the savings.
