We are talking about natural hair today. To straighten or not to straighten is the question. Well, it is definitely up to you what you want to do to your hair. It depends on what you are most comfortable with. Like they say in French, " Pour etre belle il faut soufrir." Meaning "beauty is pain". If you want to keep your hair straight all summer long you have to be ready to suffer the consequences.
If you are not sure what do with your hair I suggest that you wear you hair curly. The number one reason why you should keep your hair curly is because wearing your hair straight will not last. So you would have to use your hot tools over and over again to keep your hair straight throughout the summer. It will be you fighting against nature. It is already hot as it is. If you have 4b/4c hair, you can forget about it. Your hair will only last a few days if you are lucky. Second, constantly using hot tools will damage your hair. You probably heard of heat damage before. It is when a part of your hair is straight, and there is nothing you can do about it, and the other part is curly. A protein treatment does help in some cases, but for the most part the hair stays damage forever.
