I open locks but hold no key, I wear no mask yet guard what’s me.The stronger I sound, the softer you fall. Whisper me once and I’ll welcome them all. What am I?

I tell you your wants and needs; I am one of three. Remove my first and last, and there is nothing left to see.

Though I always seem to be in your hair, There are those who say you should honor me. If you grow me, you might be settling down.

I am a disease that children adore, I am decay in disguise, yet you ask for more. You don’t want me inside your head, Yet you watch me for hours instead.

I have a disney movie at my first four letters, but I do not have a princess in it. I am often seen in context related to vacation when you drink me..
