Q. How long should your hair be before getting a perm/body wave? I am looking to get tight curls and my hair is about 3-4 inches long. Terri Durdle; St. John’s, NL

A. There are a couple of factors to consider before having a perm service. First, how would you like to style your new curls? If you like springy curls, then any length will do, but know that hair will shrink about three to four inches when perming a tighter curl. For looser waves, hair should be shoulder length or longer in order to support the style. Second, how long would you like your perm to last? Once your strands are transformed, they will be curly until the perm grows out or is cut off. Loose curls gradually lose their wave but tight curls will have a more pronounced regrowth since the new hair will be so much straighter by comparison. (It’s kind of like coloring your hair three shades lighter than your natural shade). Most people can go three to four months between perms. By four months, you’ll have enough new growth to reperm. My advice: Discuss the options with your stylist to get a better idea of the look you wish to achieve. That way you can enjoy your investment for as long as you like.
