Hi.  I've always washed my hair daily.  The last few weeks I've tried skipping a day here and there but whenever I do I'm finding these very tiny balls on my scalp and now I'm remembering why I love to wash my head daily!  They are the size of a grain of salt.  I have no issues along with them, no itching, no visible dandruff, just these weird balls lol.  I checked Google and apparently it's a common issue but I couldn't really find any answers as to what it is or how to prevent them.  Anyone here know what I'm talking about?  Please help.
