Fresh lavender cannot directly be put into soap. Most flowers, dried and fresh, turn brown due to the saponification process of cold process soap. I’ve used dried lavender buds before in my soaps, but they will turn brown after a few months. Adding purple dye to the soap helps to hide the discolouration or you can swap the lavender buds for cornflower petals. However, most liquid soaps do not have anything in them as the flowers and other solids can block the dispenser. For liquid soaps, you can utilize your fresh lavender by infusing olive oil with the herbs. Adding a couple of tablespoons of infused olive oil will make your soap nice and moisturizing on the hands while you cleanse.
