Apple Cider Vinegar works great!  It is by far the best treatment I have found for my hair and body! When I'm in the shower I have ACV in a spray bottle and I soak my hair and spray my entire body. Wait for 10 minutes, rinse.  It kills all forms of the mite including the eggs.  I did that twice a day for 5 days, once a day for 10 days, then every other day for only 5 minutes.  It is very drying so I use Moo Goo MSM cream on my face and body.  I have long hair so after I rinse I turn my head upside down and put conditioner only on the hair, not the scalp--rinse it.  I've easily spent a thousand dollars and the cure was quite simple. Also, I bought a 32oz bottle of permethrin and I put 1oz in each load of laundry so I didn't reinfect myself.  Cedarwood oil is awesome sprayed on my mattress and around my bed,  it kills the little bastards and the house smells great! Also, vacuum everyday. Also, I am taking neem capsules, MSM capsules, and NAC as a little insurance. I rarely feel a bug and I am immunosuppressed and taking steroids. Hope this helps someone! Peace!
