- 1). Research the facts about hair straightening. Your parents are likely going to have questions about the straightening technique. For instance, they may want to know how it is done, where it is done, what long-term effects the process may have on your hair and how much it will cost. Knowing the answers to these questions will show your parents that you have put careful thought into hair straightening and that it is something you genuinely want to do. Consult with a professional for questions regarding the straightening process.
- 2). Save your money. Some parents may object to you having your hair straightened because they cannot afford to have it done. If you save your money and have at least some of the cost taken care of, they may be more inclined to let you have your hair straightened. Saving money will also show them that you are serious about this hair change. Your parents will probably also appreciate that you don't intend for them to pay for the hair treatment.
- 3). Practice what you are going to say to your parents when you tell them you want to straighten your hair. Practicing beforehand can help you to deliver your pitch in a more confident way and may help you to be less nervous.
- 4). Arrange a meeting with your parents. Hold the meeting in a quiet location, if possible, to avoid distraction. Present the reasons why you want to straighten your hair and tell them you've already done the research. Show them pictures of what straightened hair looks like. The more prepared you are, the higher your chances of approval.
