Is it considered neglect if a guardian only cuts their teenagers hair once a year.

No, neglecting a spouse is where they don't show any concern or care toward the spouse. Adults have a harder time connecting to Teens because teens minds are a sponge to anything, negative thoughts and positive.

No, not at all. To be considedered neglect, it would have to be harmful to a person. Not receiving a haircut isn’t doing somebody any harm.

out of the choices i'd say d the ability to set goals, mainly because to desire to continue you need motivation but it isn't motivation in that part, but setting goals means you have an endgame and you want to reach it which sums up motivation.
