Low air pressure. Out of balance. Wheel not true. Wheel bearings shot. Excessive wheel bearing end play. Loose/worn neck bearings. Something loose (axle, fork tube pinch bolts, etc).
If it hasn't been in an accident, then the front tire is worn, out of balance, etc. You might have something loose in the steering neck, but you didn't tell us what year or how many miles or anything else that might help figure it out.
Go to either Sally beauty supply, or have a cosmotologist go to a store with you, like five states beauty, or one that only cosmotologists can buy things at. Most of the time, they will be more expensive then what you could buy at Walmart, but the trade off is the quality. The best type is one that has a beveled edge, offset just a little bit. It tends to put a slight bend on the end of your hair so it looks like natural straight hair.
CHI irons are awesome but a bit expensive. Solano Sapphire Mini Iron won best hair straightener in Allure Magazine.
dont be fooled by all those irons claiming to be ceramic. If it is, then it will cost a lot of money. But it will be worth it! yes, Chi's have been know to be quite good, but have a tendacy to die quickly or fry hair more then most irons. Go to the link below and check out the Sedu! yes it is more expensive, but look at the b4 and after pictures and read all the rave reviews! Its amazing and I actually ordered mine today!!
