Trimming Long Hair Before Sugaring Can Reduce Pain Posted by Sugar Me Smooth on November 25, 2021 *Full disclosure - this hair is a bit longer than we recommend when using Sugar Me Smooth (but it makes for a great before and after). We recommend trimming hair to be 1/4 to 1/2 an inch before beginning. About the length of a grain of rice. This helps reduce tugging and discomfort when Sugaring!
