I would say that Lavender happens to be one of the top fragrances students put in their bath and body creations. I think it is because of the is known for its soothing, calming, and relaxing properties which would make it a great nighttime product.
For those who love lavender and want to create their very own salt scrub recipe, here is a Lavender Salt Scrub recipe from The Soap King. What is really interesting about this recipe is the introduction of liquid glycerin and lavender buds. There is no carrier oil in this recipe so maybe it is not as greasy. As you can see from the picture that there really is not much color to the salt. But according to the recipe, there is a colored mica powder. Sometimes liquid colorant can be overpowering, so if you like a light touch of color then go for the mica powder.
