Glycerin is naturally formed during the cold-process soap-making method. Glycerin is a natural humectant (softener and moisturizer) which helps draw and retain moisture into the skin and scalp. It is believed to penetrate hair and skin, softening and swelling it, making it water retentive.
Daily Hair Tip
There are different types of conditioners including pre-shampoo, rinse-out, leave-in and deep conditioning. Olive oil and other volume enhancing products may help strip hair color. When in doubt, ask your stylist.
