Head and Shoulders Classic Clean?

Do any of you use H&S Classic Clean? I like it a lot because it tends to leave the least amount of residue in my hair compared to other shampoo and conditioners. I have used conditioners over a period of time that left gunk in my hair and was totally grossed out.

I have found though that, (don't get too grossed out), when I rub my fingernail along my scalp I collect a lot of dandruff. I get annoyed about this because H&S "thing" is dandruff reduction.
