Your post talks a lot about your own personal head treatment. If you are not treating the whole house ... Other members of the household, beds, bedding, couches, chairs, jackets, hats, scarves, and an often overlooked one - the car! - then you will still have a problem. Most mattresses can just be heartily vacuumed, as can the chairs and car upholstry. Put your pillows in the dryer on high heat for at least a half an hour. If you have already, rewash all bedding on hot, then dry them on hot heat. Take all stuffed animals into a plastic bag and seal them up for two weeks.
This is, unfortunately, a huge task. Get everything in one swoop. Be methodical. Have a plan. I know what a huge pain it is. Good luck!
Update: The next treatment you use, make sure you don't have conditioner on your hair. The CDC says it can act as a barrier and the treatment may not work as well.
Also the eggs hatch in 8 to 9 days, so they also recommend TWO treatments 9 days apart.
