Funny you should ask. I never really associated that with a parasite. I just finished my first round of Humaworm and have been educating myself along the way. I did/do suffer from itchy scalp. However, it seems to only be at night when I lay my head on the pillow. I've tried every type of pillowcase (I thought it was a reaction to fabric) and then attributed it to dry scalp, perhaps, but never noticed any physical manifestation like flaking or anything. My ears also drove me crazy with itchiness. I'm just now beginning to heal and am still passing many weird things, but at least now I have hope. I don't think these things are plant matter at all. They have obvious tentacles and are quite gross. I'm looking forward to my super dose of Humaworm in 90 days. I'd like to continue the healing.
