I would say that if the thoughts are repetitive, intrusive and causing you discomfort, then even if you are not pulling them out, you still may be considered to be having OCD
with predominant obsessions (you are not acting out on your obsessions i.e you don't have compulsions)
The treatment can be both medicines and/or talking therapy. "Counseling" in its strict term does not help unless it is being used as a proxy word for psychotherapies (talking therapies).
If you have fine white hair on your body, may be they are downy hair. But if you are an adult you should not have them, as far as my limited knowledge goes, unless you have eating disorder
etc. But anyway, on this, I will defer to the experts.
Please seek professional help if this is severe/causing you much distress/affecting your life/to rule out any abnormality.
