Try to accept that your teenager has to "belong" to the group of friends and that being forced to be different can cause great distress. You may think that a certain hairstyle or sensible shoes are ideal, but you probably don't want your child to be made fun of as a result. As far as possible, let your teenager make his/her own choices about these things, even if they're not your __11__.
Permanent changes __12__ tattoos or piercings are different, thought, as they can't simply be removed when fashions move on. Explain to your teenager that these require much more careful thought than __13__ your hair orange or even shaving your head. If you're completely __14__ it, you do have a parent's right to insist that your teenager shouldn't have it done. Teenagers still need some boundaries.
