I had two trials. When on the lumbar trial, I was able to bend over the kitchen sink and wash my hair and then sponge bath. For the cervical trial, I had to bite the bullet and not was my hair for the whole week. I washed my hair the morning before the procedure and then when hair got looking not so good, started wearing a ballcap when going outside. The let up in the pain felt so good that I really didn't care how my hair looked, I was just so thankful to get the pain relief.
