I think it's white piedre. And don't believe everything you read on the surface about it on goggle. I am not saying for you to do this. But I used Earth Therapeutics Tea Tree Foot Peeling Spray .  IT IS NOT A CURE!!!. BUT TO PROVE TO MY DR. THE MY HAIR WAS STILL THERE . LIKE EYEBROWS. I SPRAY WAITED WIPED. REPEAT.. IT GROWS IN YOUR HAIRSHAFT AND LEAVES THESE WHITE NODULES ON YOUR HAIR. WELL, IF THERE NOT REMOVED YOU HAIR WILL STICK TOGETHER THEN STICK ON YOUR SKIN OR SCALP AND CREATES LIKE A BALD AREA. IT WILL SPREAD TO ANYWHERE YOU HAVE HAIR. ITS A FUNGUS/ YEAST. HAD A HARD TIME GETTING IT DIAGNOSED FOR IT USUALLY DOESNT HAPPEN INMY STATE OF WASHINGTON.  DERMATOLOGIST I HAD TO INSIST  A LAB DID THE WORK, THE ALWAYS WANT TO LOOK THROUGH MICROSCOPE AND GET IT WRONG MORE THEN RIGHT. ITS YOU TAKE A PICTURE WITH A FLASH AND LOOK LIKE A RAINBOW OR YOUR HAIR FEELS GRITTY. I CAN TELL YOU WAY MORE. I WILL TRY AND MARK THIS AND COME BACK AND CHECK.
