Try mixing 50/50 organic castor oil and coconut oil on your scalp at night. Put a towel over your pillow and sleep with it on your scalp. Wash it out in the morning with Dawn (kills the mites, and fleas, btw) and do a final rinse with the borax rinse. The castor/coconut oil helps your hair regrow. Also, take 5,000 mcg of biotin a day to help with your hair regrowing.
To make supersaturated borax, add borax by the tablespoon to a liter of water until no more will dissolve. Strain the water part off into another container, and put some in a spray bottle. Spray it on your skin and scalp as often as you like, but it's drying, so you might want to put some cocoa butter cream on after it.
This has done wonders for me. My hair was falling out by the handfuls, and now it's thickening back up nicely.
