this is so relative to the individual. Obviously if you are in a situation where you cant hide it (like wearing a hat to work or around for a while) then you have NO options, except to lie and make up some story...If not, then it is totally relative. Are you the type of person that likes to be open and tell others things, or do you prefer to maintain a certain level of privacy? You dont have to tell ANYONE. If thats what your comfterable with. Isnt that PRECISELY the reason we get hts', to feel more comfterablein our skin?
*one cavieat: if your a norwood 7 and people walk up to you and say..."uh, did you gain 10 million new hairs?" then thats a different story...no comfort in privacy there.
