So sorry to hear about the fire and losing your dogs. I just love my dogs and it had to be heartbreaking to lose yours. You've been through so much, I pray that this implant will give you the relief you need
As far as the hair, I taped a garbage bag over the leads and over my upper back, and then I put a towel around my shoulders and neck area and had my husband wash my hair using the long extension shower head as I bent way over the tub. I put towels on the floor to catch any splashed water, too. Was a big hassle, but after 3-4 days of dirty hair I couldn't take it any more. If possible, you could maybe wash your hair over the kitchen sink if you take all the precautions to make sure your incision site doesn't get wet.
