Waxing is better because it removes hair from the root. When you shave you just cut the hair, so two hours later, you can see the hair there or the blue shadow (the hair follicle below the skin). Waxing, on the other hand, not only can last up to a month, but it’s also much more permanent—over time it thins the hair so less grows back. Bonus: It exfoliates the skin as well, leaving you feeling silky smooth.
