I was successful with a ayurveda herbal mix that I applied to my entire body every night for an hour for 30 day's. Body brush and night wrap over my hair with plastic.
Look under Calamity Jane.
The herbs do two things. First, It feeds the body necessary vitamins to raise your PH. Mine had dropped to 4.5. Second, it kills the worms in the skin and waits for the babies to hatch. Scars from the sores will lesson if you don't scratch at them. Small tweezers to pull the larger worms out help otherwise you will get bumps under the skin and or they get infected for 30 days. The herbal mask dries them up faster. Body brush and wash cloth to exfoliate will help.
I made a sesame oil with a small amount of clove, tree tea and eucalyptus eo that made many pop from the skin. Sit in shower and lightly coat entire body. Use lice comb to get out of hair. The pin pricks will hurt.
There is also a golden gargle mixed 50/50, that is sprayed head to toe, 15 minutes and they will jump from your body. This method is very cold but great for collecting specimens in the shower.
Each of these works. The eggs are uneffected and waiting for them to hatch every few days is nerve wracking.
My first day gave me a good night's sleep before the biting started again. By 30-40 day's of the herbal mask I applied to my entire body was a life saver. My hair grew back with few gray and curly. I love it.
There are no quick fixes. Die off will make you sick. So dealing with an external help to raise pH is the key.
2 year's later. I still take a few baths a week with 3 cups white vinegar and 2 cups of Epson salts and soak for min. 30 minutes. Keeping up my pH to 7 keeps me healthy.
