It's not that hair knows it's length and stops growing until you cut it, there is no mechanism for it to register its own length. Rather, there is a natural rate at which hairs will break or fall out and begin to grow again, and so a person's hair can only get so long before the longest hairs are due to be culled.

    It may help if you try to sound like you almost liked it, but don't. "It's not really my thing," "Tried it, but I just don't love it," and "it just never really worked for me" are examples. Explaining that you feel like you have given it all the chance it needs, and ultimately decided it's not for you. You're not trying to emphasize negativity, just a lack of positivity, if that makes sense. This helps avoid implied criticism of someone else's tastes while conveying your preference.

    The difference is that in going to the past you have some idea of how things played out and what changes might matter. The changes that come up in time travel discussions are things like "kill this person before they do anything" or "let this guy into art school" or "cancel this one particular flight." By the time the real consequences of possible small changes are known, you need more than small changes to acheve your objective.
