Demodex brevis mites feed on the glandular cells of the sebaceous gland that attaches to hair follicles (pilosebaceous glands) and meibomian glands. The sebaceous glands produce an oily substance known as sebum. Meibomian glands produce meibum which prevents tears from rapidly evaporating. It plays an important role in eye moisture.

About 2 weeks ago I noticed 3 different knots or small mats forming in my hair, they were about the size of a quarter. I didnt think much of it because my hair is very long to my butt, and has always gotten tangled easily. I had also been sleeping alot lately and not brushing my hair after showers. Well I a friend offered to brush out the knots because she is a hairdresser. So she worked on my hair for 4 hrs one night, and didnt get out a single knot, as a matter of fact, they all got BIGGER, and hard, they formed actual shapes, one was shaped and sized exactly like a computer mouse, one was perfectly circle and flat about the size of a 50cent pc, and the third was perfectly round like a ball. The amount of hair in each knot grew, like it was attaching itself to all the hairs. They got so big and firm that I couldn't even push a safety pin into one, not even a mm in! I scoured the internet along with my friends and family for 3 days trying to find anything that even came close to what I had, we couldn't find anything because these were no normal knots.
I came across and discovered It was from an EXTREMELY rare little known condition called Plica Polonica (I suggest anyone suffering from weird hair conditions, like sticky/tacky/dark slimy-like sections of hair, anywhere on the hair, look up this condition). Doctors still know very little about the cause and there is no cure or remedy except to cut the masses of hair off. But I suspected all along this condition is actually due to a fungal or bacterial growth. I tried everything known to man to get the knots out including wearing an entire giant jar of mayo on my head for 18 hours! I tried vinager, listerine, dawn, olive oil, hot oil, everything! I ended up cutting off the hair after a week of failed attempts to even remotely loosen them. But ever since I cut them all off 2 days ago, I have been getting these big pimple like bumps all over my head.
So I tried tea tree oil directly on the bumps, and its working! I don't know what the bumps are, but I know they have something to do with the scalp hair condition Plica Polonica, and the Tea Tree oil is killing it. If you have very knotty sections of hair, or you feel something kinda sticky in your hair, I suggest doing Tea Tree oil all over your scalp. I think if I would have paid more attention to the signs and treated my hair and scalp earlier, it never would have developed into Plica Plonica.
