You can wash you body with that 2 in 1 head n shoulders product, they contain like 1% pyrthrione zinc which would make your body feel better and prevent reinfestation, I would suggest taking baths with some also, the mites likely do not like the pyrthione zinc, I know it will not kill an entire scabies infestation but it is good to implement into post scabies to help you feel more at ease and help keep from reinfestation. Tea tree oil is good for this also but it has a horrible smell and will smell your household up. I see alot of other useful tips and tricks on this forum that I have used to kill my scabies, I would start with a scabies treatment and then exfoliating and moisturizing is the second most important stage of scabies. I wish you all the best as I know how hard mentally this problem can be, it will gradually get better as time goes!
