For a lot of people, getting any kind of perm is like getting a tattoo - they need at least half a year to think about it. Well, the good news is that unlike a tattoo, a digital perm is much less permanent, and though it may be emotionally painful for some, there is zero physical discomfort (unless you count how numb your butt is likely to get after being in the salon chair for two hours). Ok, but what about the damage to your hair, you ask yourself. I hear you. No straight, flat, limpy haired girl should be deprived of beautiful spiral curls. Some hair is so fine and fragile that it can't handle a digital perm, or even heat styling products. So this post is for all you girls who dream of beautiful, bouncy waves without the money, condition or courage to get a digital perm. Let me introduce you to the "bun sock". The bun sock hair curling technique is genius. It is comfortable to sleep in, non-damaging to your hair and looks absolutely gorgeous. What you will need are a pair of scissors, an old sock that you will have to roll into a doughnut shape. For short hair you need a small sock, for long hair you will need a longer sock. Watch these videos and marvel at the results (really sorry about any commercials you may have to put up with because of Youtube). Happy curling!
