How many times can you straighten your hair in a week?

There really is no limit to how many times you can straighten your hair in a week. Ultimately the amount of times you straighten your hair in a week can range from zero times to one time to as much as 21 times (3 times a day for 7 days in a row). There is no right or wrong number.
