I am here for answers to a weird problem a number of ppl here seem to also be having, details here: http://www.medhelp.org/posts/Undiagnosed-Symptoms/Sandy-grains-on-scalp-intense-itching/show/1426371
This website is cool! I am glad to have found it and looking fwd to enjoying it. The original "sandy scalp" post that brought me here via a google search can be found in this journal: http://www.medhelp.org/user_journals/show/12858/scalp-condition
Take a look, and help if you can.
