I tried everything that's suggested for these parasites, and not much works 100%. However, I found that by washing my hair and combing it through with the shampoo on, and vigorously rubbing and cleaning my hair and scalp for 5 minutes non-stop, rinsing and then repeating, and keeping the washing, rubbing, and whatever else we do when cleaning our hair going for another 5 minutes, then combing through and rinsing, and then using a good hair conditioner and again really rubbing it into the hair and scalp without stopping, and then leaving the conditioner on while I deal with the body demodex I have all over me—washing with soap and water and again making sure I clean each area without stopping for a few minutes, stopping occasionally to rub the conditioner into my hair and scalp—it does seem to drown them. At least that's what seems to happen. I use something called Dimethicone on my skin that makes them come out, but you can only use it a couple of times a week. However, if you give yourself good treatment from the start and keep it up as much as you are able to, it will help you a lot. You can only leave the benzyl benzoate on for so long. Also, the hairdryer, if you can use it on the skin and hold it there for a few moments, helps dry it up, too. Homeopathy pellets with sulfur are excellent for skin mites and such. I think you'll find it's a combination of things that help you get rid of them for good. Good luck.
