[Grammar] countable & uncountable noun

[summer paris]

Please enlighten me on this. The difference here is that the greetings are a little cheerier, the scramble a little more intense, the silence a little more avid, and, though you may not notice it, there are more grey hairs.1. The word "hairs" - Is hair an uncountable noun?2. Does "hairs" here means or refers to many individuals?Thank you.

"Hair" is a word that is used both ways. If I'm talking about a lot of hair ("I combed my hair this morning"), then "hair" is appropriate. On the other hand, if I'm talking about just a few individual strands of hair ("I noticed a few grey hairs"), then "hairs" is correct.

So, "I noticed a few more grey hairs while I was combing my hair this morning" would be correct usage of both senses.
