While I know I still need to address the cause,( not drinking enough water and eating too much processed foods)I have found much relief to my very, very bad dandruff problem thanks to this site. I read through all the posts and did the following;
Raw, unfiltered, organic AC vinegar and tap water 1:1 ratio in spray bottle. Adjust to stream and seperated sections of hair to soak scalp. I just let it dry overnight, next morning I brushed it out and things looked better. I went to whole foods and picked up the tea tree oil.
When I got home, I added @25 drops of tea tree oil to spray bottle that had 1/2 cup ACV and 1/2 cup water. Same method of application and again, left it over night. I washed hair with my new DE shampoo and conditioner. WOW!! 90% better!! My hair has not been this shiny in ages. My scalp does not hurt. Minor,random itch.I can pull my hair back and am not worried. I have great hope that this is my answer.
Dandruff shampoos never really worked for me and this last batch seemed to make it worse. My hair looked awful. Keeping my fingers crossed and will post again after giving this method some time.
Thanks to all who posted information.
